Don't Try This at Home

Garage chemistry used to be a rite of passage for geeky kids. But in their search for terrorist cells and meth labs, authorities are making a federal case out of DIY science.
By Steve Silberman

The first startling thing Joy White saw out of her bedroom window was a man running toward her door with an M16. White’s husband, a physicist named Bob Lazar, was already outside, awakened by their barking dogs. Suddenly police officers and men in camouflage swarmed up the path, hoisting a battering ram. “Come out with your hands up immediately, Miss White!” one of them yelled through a megaphone, while another handcuffed the physicist in his underwear. Recalling that June morning in 2003, Lazar says, “If they were expecting to find Osama bin Laden, they brought along enough guys.”

The target of this operation, which involved more than two dozen police officers and federal agents, was not an international terrorist ring but the couple’s home business, United Nuclear Scientific Supplies, a mail-order outfit that serves amateur scientists, students, teachers, and law enforcement professionals. From the outside, company headquarters – at the end of a dirt road high in the Sandia Mountains east of Albuquerque – looks like any other ranch house in New Mexico, with three dogs, a barbecue, and an SUV in the driveway. But not every suburban household boasts its own particle accelerator. A stroll through the backyard reveals what looks like a giant Van de Graaff generator with a pipe spiraling out of it, marked with CAUTION: RADIATION signs. A sticker on the SUV reads POWERED BY HYDROGEN, while another sign by the front gate warns, TRESPASSERS WILL BE USED FOR SCIENCE EXPERIMENTS.

Science experiments are United Nuclear’s business. The chemicals available on the company’s Web site range from ammonium dichromate (the main ingredient in the classic science-fair volcano) to zinc oxide powder (which absorbs UV light). Lazar and White also sell elements like sodium and mercury, radioactive minerals, and geeky curiosities like aerogel, an ultralightweight foam developed by NASA to capture comet dust. The Department of Homeland Security buys the company’s powerful infrared flashlights by the case; the Mythbusters guys on the Discovery Channel recently picked up 10 superstrong neodymium magnets. (These come with the sobering caveat: “Beware – you must think ahead when moving these magnets … Loose metallic objects and other magnets may become airborne and fly considerable distances.”) Fire departments in Nevada and California send for United Nuclear’s Geiger counters and uranium ore to train hazmat crews.

A former employee of the Los Alamos National Laboratory, the 47-year-old Lazar radiates a boyish enthusiasm for science and gadgets. White, 50, is a trim licensed aesthetician who does herbal facials for local housewives while helping her husband run the company. When the officers determined that Lazar and White posed no physical threat, they freed the couple from their handcuffs and produced a search warrant. United Nuclear’s computers and business records were carted off in a van.

The search was initiated by the Consumer Product Safety Commission, a federal agency best known for instigating recalls of faulty cribs and fire-prone space heaters. The CPSC’s concern with United Nuclear was not the uranium, the magnets, or the backyard accelerator. It was the chemicals – specifically sulfur, potassium perchlorate, and powdered aluminum, all of which can be used to make illegal fireworks. The agency suspected that Lazar and White were selling what amounted to kits for making M-80s, cherry bombs, and other prohibited items; such kits are banned by the CPSC under the Federal Hazardous Substances Act.

“We are not just a recall agency,” explains CPSC spokesperson Scott Wolfson. “We have turned our attention to the chemical components used in the manu-facture of illegal fireworks, which can cause amputations and death.” A 2004 study by the agency found that 2 percent of fireworks-related injuries that year were caused by homemade or altered fireworks; the majority involved the mishandling of commercial firecrackers, bottle rockets, and sparklers. Nonetheless, Wolfson says, “we’ve fostered a very close relationship with the Justice Department and we’re out there on the Internet looking to see who is promoting these core chemicals. Fireworks is one area where we’re putting people in prison.”

In the past several years, the CPSC has gone after a variety of online vendors, demanding the companies require customers to prove they have a license to manufacture explosives before they can purchase any chemical associated with making them. Many of these compounds, however, are also highly useful for conducting science experiments. Sulfur, for example, is an ingredient in hydrogen sulfide, an important tool for chemical analysis. Potassium perchlorate and potassium nitrate are widely used in labs as oxidizers.

The CPSC’s war on illegal fireworks is one of several forces producing a chilling effect on amateur research in chemistry. National security issues and laws aimed at thwarting the production of crystal meth are threatening to put an end to home laboratories. In schools, rising liability concerns are making teachers wary of allowing students to perform their own experiments. Some educators even speculate that a lack of chem lab experience is contributing to the declining interest in science careers among young people.

United Nuclear got its computers back a few days after they were hauled away, and three years passed before Lazar and White heard from the authorities again. This spring, the couple was charged with violating the Federal Hazardous Substances Act and shipping restricted chemicals across state lines. If convicted, Lazar and White each face a maximum penalty of 270 days in prison and a $15,000 fine.

The lure of do-it-yourself chemistry has always been the most potent recruiting tool science has to offer. Many kids attracted by the promise of filling the garage with clouds of ammonium sulfide – the proverbial stink bomb – went on to brilliant careers in mathematics, biology, programming, and medicine.

Intel cofounder Gordon Moore set off his first boom in Silicon Valley two decades before pioneering the design of the integrated circuit. One afternoon in 1940, near the spot where Interstate 280 intersects Sand Hill Road today, the future father of the semiconductor industry knelt beside a cache of homemade dynamite and lit the fuse. He was 11 years old.

Moore’s pyrotechnic adventures grew out of his experiments with a neighbor’s chemistry set. He turned a shed beside the family house into a lab, stocking it with chemicals mail-ordered from San Francisco and filling an old dresser with beakers and funnels. Now retired, the 77-year-old Moore looks back on his days and nights in the shed as a time when he learned to think and work like a scientist. “The things I made, like nitroglycerin, took a fair amount of lab technique,” he recalls. “I specialized in explosives because they were fun, and I liked doing things that got results in a hurry.”

Many of Moore’s illustrious peers also first got interested in science by performing experiments at home. After reading a book called The Boy Scientist at age 10, Vint Cerf – who became one of the architects of the Internet – spent months blowing up thermite volcanoes and launching backyard rockets. Growing up in Colorado, David Packard – the late cofounder of Hewlett-Packard – concocted new recipes for gunpowder. The neurologist Oliver Sacks writes about his adolescent love affair with “stinks and bangs” in Uncle Tungsten: Memories of a Chemical Boyhood. “There’s no question that stinks and bangs and crystals and colors are what drew kids – particularly boys – to science,” says Roald Hoffmann of Cornell University, who won the Nobel Prize for chemistry in 1981. “Now the potential for stinks and bangs has been legislated out.”

Popular Science columnist Theodore Gray, who is one of United Nuclear’s regular customers, uses potassium perchlorate to demonstrate the abundance of energy stored in sugar and fat. He chops up Snickers bars, sprinkles in the snowy crystals, and ignites the mixture, which bursts into a tower of flame – the same rapid exothermic reaction that propels model rockets skyward. “Why is it that I can walk into Wal-Mart and buy boxes of bullets and black powder, but I can’t buy potassium perchlorate to do science because it can also be used to make explosives?” he asks. “How many people are injured each year doing extreme sports or playing high school football? But mention mixing up chemicals in your home lab, and people have a much lower index of acceptable risk.”

The push to restrict access to chemicals by those who have no academic or scientific credentials gained momentum in the mid-’90s following the bombing of the federal building in Oklahoma City. In the years since 9/11, the Defense Department, FBI, and other government agencies have strategized ways of tracking even small purchases of potentially dangerous chemicals. “The fact that there are amateurs and retired professors out there who need access to these chemicals is a valid problem,” acknowledges Rice University chemistry professor James Tour, who consulted with the Pentagon and the Justice Department, “but there aren’t many of those guys weighed against the possible dangers.”

A provision in the 2002 Homeland Security Act mandated background checks and licensing requirements for model-rocket enthusiasts on the grounds that ammonium perchlorate fuel is an explosive; the Justice Department argued that terrorists could deploy model rockets to shoot down commercial airliners. A bill pending in both houses of Congress would empower the Department of Homeland Security to regulate sales of ammonium nitrate, a common fertilizer that Timothy McVeigh used to make the Oklahoma City bomb. “We finally have bipartisan support and encouragement from the chemical industry on this, which is important, because we’ve seen what can happen when these materials fall into the wrong hands,” says US representative Curt Weldon (R-Pennsylvania), who is sponsoring the House bill. “As we move forward, we’re going to be taking a very close look at other chemicals that should be regulated.”

In the meantime, more than 30 states have passed laws to restrict sales of chemicals and lab equipment associated with meth production, which has resulted in a decline in domestic meth labs, but makes things daunting for an amateur chemist shopping for supplies. It is illegal in Texas, for example, to buy such basic labware as Erlenmeyer flasks or three-necked beakers without first registering with the state’s Department of Public Safety to declare that they will not be used to make drugs. Among the chemicals the Portland, Oregon, police department lists online as “commonly associated with meth labs” are such scientifically useful compounds as liquid iodine, isopropyl alcohol, sulfuric acid, and hydrogen peroxide, along with chemistry glassware and pH strips. Similar lists appear on hundreds of Web sites.

“To criminalize the necessary materials of discovery is one of the worst things you can do in a free society,” says Shawn Carlson, a 1999 MacArthur fellow and founder of the Society for Amateur Scientists. “The Mr. Coffee machine that every Texas legislator has near his desk has three violations of the law built into it: a filter funnel, a Pyrex beaker, and a heating element. The laws against meth should be the deterrent to making it – not criminalizing activities that train young people to appreciate science.”

The increasingly strict regulatory climate has driven a wedge of paranoia between young chemists and their potential mentors. “I don’t tell anyone about what I do at home,” writes one anonymous high schooler on Sciencemadness.org, an online forum for amateur scientists. “A lot of ignorant people at my school will just spread rumors about me … The teacher will hear about them and I will get into legal trouble … I have so much glassware at my house, any excuse will not cut it. So I keep my mouth shut.”

Ironically, a shadow of suspicion is being cast over home chemistry at a time when the contributions of amateurs to the progress of science are highly regarded. In recent years, citizen scientists have discovered comets and supernovas and invented tools for gauging Earth’s magnetic field. Peer-reviewed journals like Nature now welcome papers coauthored by auto-didacts like Forrest Mims III, who studies solar storms and atmospheric conditions at his home observatory in Texas. Personal computers, digital cameras, and other consumer electronic devices are putting more accurate means of recording and measuring phenomena into the hands of home tinkerers than were available in high-end labs just a few years ago. The Internet is the ultimate enabling technology, allowing amateurs to collaborate with their counterparts at NASA and other organizations.

Porting the hacker ethic to the nonvirtual world, magazines like Make and blogs like Boing Boing are making it cool for geeks to get their hands dirty again, offering how-tos on everything from building your own telescope to assembling an electronic insect army. DIY robotics-fests like Dorkbot (“people doing strange things with electricity,” according to the Web site) are taking off from Boston to Bangalore.

But the hands-on revival is leaving home chemists behind. While surplus lab equipment is available on eBay, chemicals are subject to the site’s filtering software, which tracks or blocks the sale of items tagged as hazardous by the US Postal Service, the Drug Enforcement Administration, and the Environmental Protection Agency. “There are very few commercial supply houses willing to sell chemicals to amateurs anymore because of this fear that we’re all criminals and terrorists,” Carlson says. “Ordinary folks no longer have access to the things they need to make real discoveries in chemistry.”

The heyday of home experimentation in the US coincided with the rise of the Porter Chemical Company, makers of the legendary Chemcraft labs-in-a-box, which contained enough bottles and beakers to perform more than 800 experiments. At the height of its popularity in the 1950s, Porter awarded college scholarships, mined its own chemicals, and was the biggest user of test tubes in the US. The company produced more than a million chemistry sets before going out of business in the 1980s amid increasing liability concerns.

One kid whose interest in science was sparked by the gift of a chemistry set was Don Herbert, who grew up to host a popular TV show in the 1950s called Watch Mr. Wizard. With his eye-popping demonstrations and low-key midwestern manner, Mr. Wizard gave generations of future scientists and teachers the confidence to perform experiments at home. In 1999, Restoration Hardware founder Stephen Gordon teamed up with Renee Whitney, general manager of a toy company called Wild Goose, to try to re-create the chemistry set Herbert marketed almost 50 years ago. “Don was so sweet,” Whitney recalls. “He invited us to his home to have dinner with him and his wife. Then he pulled his old chemistry set out of the garage. It was amazing – a real metal cabinet, like a little closet, filled with dozens of light-resistant bottles.”

Gordon and Whitney soon learned that few of the items in Mr. Wizard’s cabinet could be included in the product. “Unfortunately, we found that more than half the chemicals were illegal to sell to children because they’re considered dangerous,” Whitney explains. By the time the Mr. Wizard Science Set appeared in stores, it came with balloons, clay, Super Balls, and just five chemicals, including laundry starch, which was tagged with an ominous warning: HANDLE CAREFULLY. NOT EXPECTED TO BE A HEALTH HAZARD.

“It wasn’t really something you could use to teach kids about chemistry,” acknowledges Thomas Nikosey, head of Mr. Wizard Studios, which handles licensing for the 88-year-old Herbert.

Kits that train kids how to do real chemistry have yielded to innocuous science-flavored toys. At the Web site Discover This, one typical product promises lessons in making “rock candy, superbubbles, and molding clay … without blowing up the house.”

One of the few companies still selling chemistry sets worthy of the name is a German-American venture called Thames & Kosmos, run by former Adobe software engineer Ted McGuire. The company’s top-of-the-line kit, the C3000, is equipped with a full complement of test tubes, beakers, pipettes, litmus paper, and more than two dozen useful compounds. But even the C3000, which retails for $200, comes with a shopping list of chemicals that must be purchased elsewhere to perform certain experiments. “A lot of retailers are scared to carry a real chemistry set now because of liability concerns,” McGuire explains. “The stuff under your kitchen sink is far more dangerous than the things in our kits, but put the word chemistry on something and people become terrified.”

The chemophobia that’s put a damper on home science has also invaded America’s classrooms, where hands-on labs are being replaced by liability-proof teacher demonstrations with the explicit message Don’t try this at home. A guide for teachers of grades 7 through 12 issued by the American Chemical Society in 2001 makes the prospect of an hour in the lab seem fraught with peril: “Every chemical, without exception, is hazardous. Did you know that oxygen is poisonous if inhaled at a concentration a bit greater than its natural concentration in the air?” More than half of the suggested experiments in a multimedia package for schools called “You Be the Chemist,” created in 2004 by the Chemical Educational Foundation, are to be performed by the teacher alone, leaving students to blow up balloons (with safety goggles in place) or answer questions like “How many pretzels can you eat in a minute?”

“A lot of schools don’t have chemistry labs anymore,” explains CEF educational coordinator Laurel Brent. “We want to give kids lessons that tie in to their real-world experiences without having them deal with a lot of strange chemicals in bottles that have big long names.”

Many students are ill at ease when faced with actual compounds and lab equipment for the first time at school. A study of “chemistry anxiety” in the Journal of Chemical Education concluded in 2000 that “the presence of this anxiety in our students could be a contributing factor in the overall poor performance of high school students in science.” (Commonly reported fears included “lighting the Bunsen burner,” “fire,” and “getting chemicals on skin.”) Restrictions on hands-on chemical experience is “a problem that has been building for 10 or 15 years, driven by liability and safety concerns,” says John Moore, editor in chief of the JCE.

“The liability issues are a cop-out,” says Bassam Shakhashiri, the author of a four-volume guide to classroom chemistry who has taught for 36 years at the University of Wisconsin-Madison. “Kids are being robbed of the joy of discovering things for themselves.” Compared with students in previous generations, he says, undergraduates raised on hands-off science seem passive: “They want someone to do things for them. Even those who become chem majors and grad students are not as versatile in the lab, because their experiences in middle school and high school were so limited. This is a terrible shame. By working with real substances, you learn how to ask the right questions about the physical world, which is half the battle in science.”

Paradoxically, at a time when young people are particularly excited about technology, their enthusiasm for learning about the science behind it is waning. Thirty years ago, the US ranked third in the world in the number of science and engineering degrees awarded in the 18-to-24 age group. Now the country ranks 17th, according to the National Science Board. A 2004 report called Trends in International Mathematics and Science Education Study found that while fourth graders in the US rank sixth in basic science scores when measured against their peers worldwide, by the time they’re in eighth grade, they’ve slipped to ninth place. Prompted by concern that America is falling behind, President Bush proposed a $380 million “competitiveness initiative” this year that promises to train 70,000 new teachers of Advanced Placement science and math. By the time students have the opportunity to enroll in an AP course, however, many have already absorbed the message that science is best left to trained professionals.

“You have to capture kids’ imaginations very young or you lose them forever,” says Steve Spangler, a former protégé of Mr. Wizard who is now a science correspondent for the NBC affiliate in Denver. “But that’s hard when you have teachers required to check out vinegar and baking soda from the front office because something bad might happen in class. Slowly but surely the teaching tools are being taken away, so schools end up saying, ‘Let’s get a college professor to do this demonstration, and kids can watch the streaming video.’”

To Bill Nye, the “Science Guy” who hosted an Emmy award-winning series on PBS in the 1990s, unreasonable fears about chemicals and home experimentation reflect a distrust of scientific expertise taking hold in society at large. “People who want to make meth will find ways to do it that don’t require an Erlenmeyer flask. But raising a generation of people who are technically incompetent is a recipe for disaster.”

To ensure that the tradition of home chemistry survives, self-proclaimed “mad scientists” are creating a research underground on Web sites like Sciencemadness, Readily Available Chemicals, and the International Order of Nitrogen. There, in comfortable anonymity, seasoned experimenters, novices, and connoisseurs of banned molecules share tips on finding alternative sources for chemicals and labware.

One key to working as a DIY chemist, says Matthew Ernst, the 25-year-old host of Sciencemadness, is realizing how many useful chemicals are still available as household products or items designed for specialized niches. Silver nitrate, for example, can be found at potters’ supply stores, where it lends raku glazes an uncanny luster. “Amateur chemists become compulsive label readers,” Ernst says. “Many compounds are available if the chemist is willing to split his shopping between the paint store, hardware store, ceramics supplier, gardening center, welding supplier, feed store, and metal recycler.”

Out-of-print texts like Julius B. Cohen’s 1910 Practical Organic Chemistry are being made available again in PDF form on file-sharing networks and the Internet Archive. To route around stigmatized chemical pathways, home experimenters are reviving 19th-century methods of synthesizing reagents from scratch. Shawn Carlson of the Society for Amateur Scientists calls this “embracing Grandpa’s chemistry.”

Carlson’s group acts as a virtual co-op for its nearly 2,000 members by facilitating small purchases of legal chemicals and equipment. The group is also launching an ambitious national program called Labrats to provide mentoring to the next generation of researchers by teaming students with working scientists.

The father of three young children, Carlson understands parental concerns about safety. But he believes that the exhilaration of risk has always been a powerful factor in engaging kids’ interest in science, and should be actively encouraged – while minimizing the physical hazards. “We can get rid of most of the actual dangers, but it’s important that we preserve the perception of danger in science,” he says. “When I do experiments with my own kids, I’m more than happy to let them believe that if they’re not careful, something could happen to them. It adds that extra element of ‘my fate is in my hands – but if I do this right, everything will be fine.’”

In March, Bob Lazar and Joy White were building a new two-story home for United Nuclear in a clearing behind their house, hiring three assistants, and weathering a nerve-wracking shortage of aerogel after Boing Boing posted a link. Then news of the Justice Department’s charges against them arrived, and they called their lawyer to begin planning their defense.

“Kids read about the great scientists and their discoveries throughout history, and marvel that people once did these things,” Lazar says. “But they marvel a little too much. Taking chemicals and lab equipment away from kids who love science is like taking crayons and paints away from a kid who may grow up to be an artist.”

Its a little bit scary, thankfully its not like that over here, and I guess that was probably an isoalted case or at least I hope so. Seems a bit like banning cars because a few people might use them for hit and runs.

That is total paranoid nonsense. Anybody that has ever flow model rockets would know that hitting a moving target with one is almost impossible. How many years did it take engineers in the defense industry to develope guidence systems for missles? Decades. To think that is even close to realistic is absurd.

guy · Jun 1, 2006

if you want to persue an education in science it may be looking out from america to gain it. they did all this in the uk many moons ago along with the rest of the education system.

shooting down aircraft with hard to manufacture, temperamental amateur rockets????? aren't high powered rifles and other lethal weapons more adequately provisioned to do such a better job and much more easily obtained???? if the terrorists wanted to bring more aircraft down could they not just shoot them down??? i doubt attacking the education system will do much good. any way by looks of things the american government wants everyone to start at year zero in the name of freedom.
