Blow GIANT smoke rings!

Many apologies for the total lack of good, hard, bad science on this site lately. I have a few items to bring to your attention but sadly no time to properly write about them, being as I am working no less than three jobs (one full time, two fun-time), moving house, being ill and a host of other annoyances.

Console yourselves, then, with this video demonstrating a homebrew air cannon capable of blowing giant smoke rings!
