this is the bubbler/bong i made after reading this thread,, i found a round looking soap dispenser ( the kind you push on the top to make the soap come out) , i took off the pushy top thing and the spring and i had a stem for it which was already part of the bottle, and i drilled a hole on the side, cut a pen in half and put the pen in the side for a mouthpiece and put a bowl type piece of metal on the top for a bowl, it hits pretty good
