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.

Earthquakes and Tsunamis

I frequently get questions about earthquakes that causes devastation, so I thought we would experiment a bit to help you understand more about them. This is a topic that many people, and the news media especially, frequently misunderstand.

Muscles Don't Push

It has been a while since I did a biology related experiment, so this week we are going to take a look at how your muscles work. In particular, we are going to examine the muscles that move your arm, to see what is really involved in moving your body.

Dirty Words of Science

This experiment is a result of quite a few e-mails that I have received over the years that I have been writing the Experiment of the Week. I hope that it will show some of the communication problems that can occur when scientists and "normal people" talk to each other.

Cat Lapping

This experiment comes from a recent event in the science news. Researches have discovered that cats drink in a very different way from dogs and other mammals. Now you might think that things like this had been completely explored decades or even centuries ago, but high speed photography has shown us things that we did not suspect before.

Breathing Hot and Cold

One of the most common questions that I get is where do I get the ideas for these experiments. Some are old classics that I try to give a new angle. Others are the result of questions sent to me by subscribers. Some of the ones that I like the best are the ones that just pop up, seemingly out of nowhere. This is one of those. It also comes with its own story, which makes it even better.

The story is one of Aesop's fables. If you have never read any of these, go read some. It is well worth the time.
