The Man in Blue is the alter ego of Cameron Adams, a Web Technologist in Melbourne, Australia. (That means he does graphic design, HTML/CSS, JavaScript, writing, server-side jiggery pokery, and anything else that takes his fancy that day.)

Okay, the baking soda volcano is the kitchen equivalent of a volcano, not a real one. It's cool all the same! The baking soda volcano is also more or less non-toxic, which adds to its appeal.

You know how some demonstrations have the disclaimer "do not try this at home"? Online High Tech Magazine has a video of one of these demonstrations that I'm sure I'll do anyway (though I expect to need a new microwave). Apparently if you set a wooden toothpick on fire in a microwave (I'm guessing a lighted match works) and turn the microwave oven on, you'll see a periodic discharge of plasma or ball lightning. Plasma is a state of matter, similar in some ways to a gas, except involving ionized particles that are pretty far apart from each other. If you try it, be advised you shouldn't... it can't be good for your microwave oven and possibly presents a health hazard... but feel free to take pictures and send them to me.

Do you have money to burn? Here's a neat trick for setting a dollar bill on fire, without actually burning it. This demonstration illustrates the concept of combustion and also shows some properties of alcohol, water, and money.

Here's another classic chemistry demonstration for you. Pour a glass of 'water' into an apparently empty glass, and watch it change from clear to wine or blood red. Blow air into the red liquid to clear it.
