These experiments are from Robert Krampf - The Happy Scientist
301 - Scratch Science - We have all gotten a scratch now and then, but most people never
learn the science involved. If you think about the science, you might not
notice that it hurts so much.
302 - Fiber Optic Water - Why does light travel so well inside water, even when the stream is bent?
303 - Obedient Coin - A magic trick with coins.
304 - Observation of a Candle - I am once again rereading Michael Faraday's Chemical History of a Candle. You can find the entire book online at http://www.bartleby.com/30/7.html. This week we will take a few minutes to look at some of the marvels involved in the burning of a candle.
305 - Floating Finger - This is a really simple experiment that shows some of how our eyes work.
306 - Magnifying Glass - A glass of water acts as a lens to magnify objects inside.
307 - Bernoulli in the Shower? - This week's experiment came as an accidental discovery while working on a different experiment idea. I was playing with ideas for showing how inertia helps remove water from your clothes in the spin cycle of the washing machine. In the process, I saw something interesting and made a wrong guess, which led to even more interesting discoveries.
308 - Static Glow - How can a balloon produce enough electricity to light a fluorescent bulb?
309 - Magnetic Money - This week's experiment is the result of a teacher asking for experiments with magnets. If you have ever played with magnets, you know that they attract iron, steel and some other metals. But what about money?
310 - The Shuttle Tragedy - The most common question I have received is about the debris from the shuttle. On reentry, a shuttle experiences tremendous heat. That is the reason for the special tiles. Some of the pieces of debris that have been found were materials that would be quickly destroyed if exposed to that much heat. How did those materials make it to the ground without burning up?
