I was just thinking... You could put another tube over the top of the shaft on your bong to make even a really small bong into a pretty big one! You could also make insanely and uselessly large bongs from like 10 ft of pipe! The warning label on a bong as such would read : Caution! Do not try to clear the chamber in one hit!
hahahhaha. i saw a huge bong in a pic once. the fuckin bowl was like an oz and u had to stand on a ladder to hit from it. they used this huge tourch thing to light it. it looked pretty. awesome.
I made a 4 foot tall bong before, I don't remember what happend to it. I think my friends grandama threw it out along with our home snoopy bong, god I loved that thing.
My friend once made a 7ft bong with a plexiglass (or whatever plastic like transparent material) ... It was cool. You needed two people, one to smoke and the other to light. You were pretty good when you could clear the whole tube of cream smoke. We called those, ''Milk tea hits"
