this is my version of an incredibowl, made from some fittings, springs, and a bottle/tube. i got the urge when i saw my first actual incredibowl, and it works exactly the same. For those who dont know; an incredibowl is a spring loaded bowl, attached to a chamber. to clear it you simply pull on the spring loaded cap and the smoke is replaced by fresh air. Im interested in as much criticism as possible, dont be shy.
Those are actually pretty legit! I'm a fan... Is that pipe on top hard to hit? Looks like I'd have trouble making that an air tight seal.
it's not to bad, usually, if you cant get a good seal you just turn it until you do. however i haven't had many problems with that, since the edges of the bottle are curled. ive been thinking of making another adapter to go over the nose from a 2-liter as well.
