hey guys these are the three "tube bubblers" i've found so far. the water tool of the pinnacle, the cloud hydro tube and the vivape aqua vape. maybe we could collect all of these here since I'm interested in getting one of these small and portable water tools or whip adapters. I'm sure a lot of you guys wat one, too. most of them seem pretty expensive but with the right equipment you can use them with more or less all devices! the aqua vape is the cheapest one, i think. can someone tell me how big the standart sized one is? which one is the best? which ones I've forgot?
