Professor Clint Sprott, David Newman, Chris Watts, and Uma Bhatt, from the University of Wisconsin, are all part of a program called "The Wonders of Physics".  The other day I came across a few more cool physics experiments that you can do at home so I figured I would pass them on to you here:

Home Meteorology
Your Reaction Time
The Doppler Effect
A Random Walk
A Vortex Bottle
Smoke Rings
