Cloud in a Bottle

I saw first saw this experiment on TV and decided to replicate it. I'm using a lemonade bottle, a tire valve, and a modified tire inflation compressor with a pressure gauge driven by a corded drill. It works by building up pressure in the bottle with some water (cloud juice) and suddenly releasing it. The fog is caused by the sudden loss in pressure.

                                                           only 5 to 30 psi required

This is the cloud coming out of the bottle.
