Cool Water

This experiment comes from washing the dishes. If you look around this site, you will find that a fair number of my experiments have come from washing dishes, which is probably the result of the state my mind is in when my belly is stuffed with yummy food.

Brain Freeze

This experiment comes from a question that I got from a subscriber. As I researched the question, it was even more interesting than I expected. It also seemed like a good excuse to eat lots of ice cream.

Bad Chocolate?

I mentioned that I had a lot of fun experimenting with carbonated soda (and drinking it) and that I should do an experiment with chocolate. I got quite a few e-mails suggesting experiments with chocolate, but this one was the most common. It has to do with the white discoloration that you sometimes find on old chocolate.

Arm Raising

This experiment is something that we used do for fun when I was a kid. (No jokes about dinosaurs or the Dark Ages, please.) It was back in the days before video games and the internet. Back in the days when there were only 4 TV channels and you had to get up and turn the dial on the TV to change the channel. Even so, we still had lots of fun. This is a science trick that always amazes people.

A Real Tuning Fork

If you have ever played with a tuning fork, you know that they are interesting and fun, but they can also be expensive. For this experiment, we will use a regular fork from your kitchen to produce a beautiful tone.

Pinhole Eyeglasses

This experiment is something that I ran into MANY years ago when I first began wearing glasses. If you wear glasses, then you know how challenging it can be to find your glasses if you have laid them down and can't remember where you put them. You need your glasses to find your glasses. This is a way that you can make a quick, emergency pair of glasses for yourself or someone else that needs them.

A Color You Can't See

Think of all the colors you can see? Think about rainbows, field full of flowers, and holiday decorations. With all of the colors that we can see, there are many more that we can't see, at least with just our eyes. With the help of a cell phone, you can see some of those invisible colors.
