like you know how you can buy ash catchers/diffusers/ percs/etc. for bongs. What accessories exist for bubblers?
If you get a scientific glass bubbler with a glass on glass joint then you can use most of the same accessories: ach catchers, carbon filters, domes/domeless concentrate attatchment
you'd need a gong style bub, then you've got all the same attatchments as you do for bongs. And I really haven't seen to many gong bubblers, just one in fact, and it had an even smaller joint size than a 14.4
any GonG bubble you should be able to buy accessories for, but it will make even more drag because its a much smaller piece than a bong. diffused downstems and bowls, carbon filters, etc.
