were you using any logic when thinking of this? first you would have to think what kind of tube because many types of tubing dont conduct heat quick enough threw them to make any difference at all. This is especially true when you think about the speed at which the smoke goes threw the tube when smoking it. The entire thing is actually the most pointless and un necessary thing i have ever encountered because a regular bong makes it cooler when the smoke goes threw the water and you get the added filter of the water as well. Sry guy but sticking tubes and shit in your bongs or adding handles to your bowl isnt a new way of smoking. learn to roll a joint and you might come up with somthing new.
