They're called resonators. A friend of mine has one, but I've never seen it....

I agree with Herbal, it sounds like it would make it taste terrible, and load it with teh carcinogens...
altoids Reviewed by altoids on . Pipe that collects resin in the weed? Have any of you heard of a pipe that collects the resin in the weed? Apparantely, it has a special compartment that you place some bud in. Smoke up a few times, and the weed collects all the resin. Remove the weed, and enjoy. Although Im not a big fan of Resin, this sounds like a cool idea. Anyone ever seen one before? Rating: 5
