Learn how to create a water vortex by drilling a hole at the bottom of plastic aquarium  to act as a drain.

If don't have an aquarium just fill up your sink and then release drain plug.  Stir in a circular motion and watch vortex form from above.

I highly recommend using a perfectly square tank.  Any tank that has more of a rectangular shape will make it much more difficult to produce vortex.  

Tank I recommend is the the Tetra 29095 Cube Aquarium Kit, 3-Gallon.  Some of these shots were even captured with a cube tank that was only 1/2 gallon.
