It seems multipe chamber bubblers add additional filtration. Why don't we get the same filtration from a bong that holds more water? It seems if you had a bong that held as much water as a 3 chamber bubbler you should be able to get the same filtration. Is there something that happens when the smoke goes in the water, comes out and goes in again? You get better hits from bongs when you don't fill them to the brim, why is this? Also, what gets you higher, a bubbler with a bunch of chambers or a decently sized bong?
if you over fill a bong you get drag = shitty hits also bubbles wont stack properly giving you a shitty hit
bongs can have multiple chambers too, there call percs as the smoke passes thru more water chambers the smoke cools down and the hit become smoother, but with more water chambers you loose the taste of the bud. & NEVER fill your bong or bubbler to the Brim, fill it about an inch above the hole/slits
