Do a beer hit. Its where you cut a hole in the bottom of a bottle and cover it with your thumb, fill the bottle with beer and use the same bowl from your gravity bong, you then have a friend hold a lighter over the bowl while you chug the beer, pulling the smoke in to the bottle. Once the beer is close to gone your friend removes the bowl and you get a huge hit of weed. Try Sam Adams to, its pretty good. I like the pale ale.
dude can i ask one thing, how do you open up a hole without beer spraying everwhere, do you like tilt to some angle to get the carbon to the bit?
i think i posted it earlier in this very thread, but yea you tilt the can so the air pocket is right where u are poking the hole, then once the hole is poked u can rip it open to a size of your liking
