Egg in a Bottle

This experiment is a classic. If I had to pick the one science experiment that I have seen in the most science books, this now would be it. But it is also a very misunderstood demonstration. You will find that even many books of science experiments get the explanation for this one wrong.

The Science of Campfires

This experiment comes from my neighbors at the Malibu Creek State Park campground. While taking my morning walk, I heard a lady bragging to her husband that she started the campfire with only one match. That made me think of the fellow that I watched the night before as he poured two bottles of charcoal lighter fluid onto a pile of wood and still failed to get the fire going. He would pour on the liquid and get a huge blaze, which quickly died. How could the heat of one match work better than a gallon of blazing lighter fluid?

Black and White Smoke

Sorry this week's experiment is late.  I got caught up in answering a question from MSNBC's Countdown program.  It turned out to be interesting enough for me to put the planned experiment for this week back in the file and write a new one.
