Third vortex experiment of 2010 (2010-08-07). A vortex machine like this is made by many (4 poles with holes), but I wondered what would happen if we'd crank up the power!
This machine is constructed by artist Roy Jongeling

Second vortex experiments of 2010 (2010-06-01). The little tornado got up to 2.8 meter high this time! The stability of the surrounding & drive air, is much better than last time, but it can still be improved a lot. A huge tornado can be dangerous, but a small one like this is very fragile. If the conditions aren't just right, it disappears in less than a second.

First vortex experiments of 2010 (2010-04-18). The little tornado got up to 1.5 meter high this time. The improved smoke table made the vortex more clear to see. The previous experiments showed that everything heavier than air gets thrown out of a vortex, and this fire vortex shows that fire -being lighter than air, wants to go to the center of a vortex. The fans on the sides proved to be essential for a vortex this tall. The stability of our vortices, we're going to improve that next time.
