leapold Reviewed by leapold on . 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 Rating: 5
