Power Bong

Two-Way pump Bong

The idea is pretty simple, if you had a two-way piston style pump ( that blows air on the up and down stroke) put a bowl on the air intake and pump away, each stroke should fill the cylinder with quite a bit of smoke. But do it slowly because the air pressure can be a lot.

I haven't figured out what type of lubricants to use, the ones that come with the pump seem to get gummed up quickly. The only solution I've found so far is to use someone elses pump.

       I have a cd rack which has little bubble columns either side. You can stick a joint in the intake for the air pump and hey presto an automated bong.

       Look into using hemp oil as a lubricant. If it mixes with your payload, no big deal.
