Just a quick vid of the vacuum engine or "flame licker" engine. We'll have a better one up soon.

The Vacuum engine works by 'licking' flame and heat into the chamber. You can see it in action during the close-ups of the video.

A 91% rubbing alcohol solution was used as fuel. A more pure alcohol can result in a more consistent engine run.
