make a bong, i think thoses work best. just take milk carton or anything else along that size, cut a hole about half way down, make it so a pen can fit in it(hollow out the pen by taking off the back and tip and the ink catridge thing in it) then make a bowl out of alluminum foil, or tin foil w/e lol, slap that on the end of the pen tahts out side the bottle, tape the outside of the bottle and pen so air cant get through that ez and so the pen stays still then put water inside(has to b at least enough to cover the end of the pen inside) then fill the bowl, light it and toke ..if u dont want to make a bong...then find some1 on here that will sell a pipe or u can make one out of clay
