Water Vortex

In this video I build a water vortex. The vortex is created by means of a brushless motor. The drive shaft is sealed by a very easy to build waterproof bearing. I have tested different Probeller to see what vortex they produce. The vortex is strong enough to pull a Syropor ball down. I show the physical principle of a vortex. Watching a vortex can be a very exciting thing.
