I want to have a 2 liter, cut it in half, put a hole for the bowl on the top half, put a hole for a bread bag on the top half, fill the bottom half with ice water, squeeze the top part into the bottom, Question: When you light it and push down and pull up repeatedly on the bottle so it slides up and down, will that cause suction on the bowl? What are some other complex bong ideas, where can i find them?
