What u need:

water bottle
lighter
foil
door stopper
sharpie

1st: take the sharpie and pull off the cap slightly so that when u pull down as if u breaking it there is leverage if u do it right the black part of the sharpie should pop off. take out the "guts" so that u just have the gray tube. cut the closed end with a kife as if u are sawing it this should be quite easy if its not try a little futher up not much though.

2nd: take your water bottle and lighter and burn a small hole (tip: when the plastic frist starts to melt try and shove the tube in at an angle if it does not fit light the plastic a little more then repeat the angled shove) about 1/3 of the way up. Be sure to put the cut end of the tube into the bottle.

It should look a little lke this


3rd: take your door stopper and foil. put ur index finger in the middle of the foil and pull the foil up. this should incase your finger u want the foil to reach the frist line on your finger so incaseing you whole finger is not nessasry unless u enjoy cuting. put ur finger in the wide end of the door stopper and pull the foil off. WALA ur bowl. ( you can ajust the size of ur bowl at any time and if u use the bong on a regular basis u might want to change out the foil every so often to) take the fol bowl out and poke holes in the bottom with a needle, safty pin..etc. it should look like this ( with water)



fill with water so that the end of the tube is submerged and load the bowl....... u no what to do now
