Easy Gravity Bong

Save one of those short, fat Gatorade bottles and rip the label off.
Cut the bottom off.
Tape a freezer bag (any size, depends on how big of a hit you want) airtight around the open bottom.
Drill small hole in cap, slightly smaller than the size of a metal bowl. Screw the bowl in the hole you drilled and melt the bottom a bit so it's also airtight.
You can also drill a hole in the side of the bottle if you want a carb.
Pack it up, hold the bottle between your legs and reach under. Light it, and slowly pull down the bag. It may take a few tries to master, but this can deliver huge hits for one person. Save the cap and make a new bottle with a new bag when the old one gets dingy. This is a great way to covertly pull massive hits on road trips and such (down low between legs). We've done the same for giant Hawaiian punch containers and I've sucked down a whole one of those, cashing the whole bowl. :silly:

My friends and I "invented" this back in our first or second year of college, though I'm sure there are similar ones. We coined it "The Alphonso"

Anyone else build their own things like this? I'de be psyched to hear about them. :hippy:

lol its called a lung....
im pretty sure everyone has heard of it..

Great then my stoned feet just joined the forums and the first thread I started was meaningless!

Fantastic!

That doesn't mean I don't want to hear about newer, slicker inventions. Thanks for everyone that posted. I'm thrilled. Oh, and rolling a blunt of G-13. Hey buddy! Where have you been all my life?!
