You can make this terrific tornado using a fish-tank pump.
The outlet of the pump goes through a plastic pipe to the top of a cut bottle.
The water from the bottle goes to the inlet of the pump.
Here is the full assembly.
Fill the cut bottle with water up to the level of the pipe.
Then start the fish tank pump.
Water will swirl around the periphery of the bottle creating a vortex.
Soon you will see a beautiful CONE.
Place a Styrofoam ball in the vortex and it will be sucked in.
You can see water spinning and swirling like a real Tornado.
A Styrofoam ball placed in it will be sucked in this Black Hole.
