The samething as the first video, but this time I tried to show the donut pattern of water movement better. The Egg propeller is attached to a 7.2 volt electric motor which I'm running at 6 volts from 4 double A batteries. The vortex is unstable due to the fact that my egg propeller only has one fin spiraling around it. It should have 2 fins to make it stable, which is seen in nature, for example, a galaxy always has 2 spiral arms or more. Never just one as far as I know.
