Tornado Experiment

I found some directions on how to create a tornado, like we had talked about. The site I found it on was:

Tornado in a Jar

Need: tall plastic jar (pop bottle), 4 to 6 small balls of aluminum foil, clear liquid soap, water, blue food coloring.

Place a teaspoon (5ml) of clear liquid soap in your plastic container. Drop into the jar 3-4 vary small pieces of aluminum foil rolled into balls. The foil should be folded and pressed so that it will sink. Fill the jar to the top with water. Add 1 to 2 drops of blue food coloring.

Rotate the container and a swirling effect should be produced. It may take some practice. Set the container up on the table and watch. The force of the foil at the bottom should keep the water in motion. The action resembles the motion set up as circular rotations of air in the atmosphere form a tornado.
