What Happened?

The original idea of creating fog filled bubbles came from a demonstration presented by Bob Becker in 1995 called a Leaky Faucet. Fog filled bubbles dropped from a “faucet” made out of PVC pipe. We’ve updated this idea by being able to control the flow of the carbon dioxide gas with the flask and tubing.
