Bubblers

Bubblers

The best of both worlds: hand-pipe portability with water filtration. 169 bubblers from DankStop, Valiant Distribution, GRAV, starting at $14.7 — hammers, sidecars and double-chamber pieces that actually diffuse instead of just gurgling.

Look for a fixed downstem with slits (that's where the smoothness comes from) and a flat base that survives the coffee table. Most here clear those bars easily.
