one at my local head shop... i'll see if i can find one on the net...

i made mine tho... out of a full faced gasmask a painter used to use (inverted the inlet valves where the filters used to be (think ww2 gas masks) so they let air out, instead of in, and there was a gasket place on the bottom where something else attatched (not sure what lol) which i rigged to fit my acrylic bong (it clipped on and off) works perfectly :stoned: anyone who's smoked with me has begged to try it, but it's not a regualr thing... not only does your eyes burn like damn hell, but they burn weed bad... it's not like a regular bong where you take a hit and w/e... you're constantly breathing smoke when used right... which is also why you get so high...

instead of being able to breath fresh air, you're constantly breathing smoke for however long you stay in it... (usually only lasts a couple breaths <.<;;; lmfao... i never had anyone even cash the whole bowl in one.... i mean you get high, but you also feel lightheaded as hell... the longer yous tay in, the closer you get to passing out.
