quick question

I've never used a bubbler before but I'm thinking about getting one. Can you smoke one without water? Just curious. Also how big are they usually? Small enough to fit in your pocket?

yes, and it depends

with no water they smoke exactly like a pipe and for size, they can range from one that fits in your pocket to one like friends that was over a foot tall.

You COULD smoke it without water, but its soo much better with.
