Classic Chemistry: Colorize Colorless Liquids with "Black" Magic, AKA the Iodine Clock Reaction

Want to make boring old colorless water brighten up on command? Well, you can control the color of water with this little magic trick. Actually, it's not really magic, but a classic science experiment known commonly as the iodine clock reaction, which uses the reactions between water and chemicals to instantly colorize water, seemingly by command. You can use different colorless chemicals to produce different colors, and you can even make the color vanish to make the water clear again.

How To: Experiment with circular motion

This video shows various experiments with circular motion. In Dr. Carlson's Science theater he uses water, a lit candle, and a piece of paper to show the ways that circular motion causes gravitational pull. The water in a glass doesn't spill as it is spun around 360 degrees in a circle, even upside down. The flame on the candle was pulled toward the center when spun around. The piece of paper becomes a paper saw and was able to cut wood when spun. He not only demonstrates centrifugal force wi...
