well later on that night i decided to make a water bong that looked kinda cool.
took a water bottle, got some cold water put in it. then took a knife and cut out a hole big enough for a flexy straw to fit in. then taped it up so that it was air tight. ( with the cap upsidedown) then taped the cap down. and cut a hole in the side above the water lvl and made it air tight. then went out to my shed and had about 10-15 long hits (friend did the same) and i got very little out of that and the hole dam cap was full.. dam Im not doing something right or im just immune.
