A Long Lens


This week we will see that you can do science experiments anytime, even while cleaning out the refrigerator. Well, to be honest, it distracted me from cleaning out the refrigerator, but eventually the job will get done. I
promise. I really do promise. To avoid cleaning your refrig.... I mean to try this experiment, you will need:

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.

Dancing Raisins

This experiment is another old classic which is still a lot of fun. Now that I think of it, it seems that most of the science tricks I did as a kid have become OLD classics, but this was already an old classic even way back then.

Creeping Carpets

This experiment is one that has been "cooking" in my mind for a while now. Today I had carpets on my mind, since I was cleaning them with our new carpet cleaner. We live at the beach, and our carpets tend to get dirty and sandy, so we place small rugs along the pathway that gets the most use. One problem is that the rugs don't stay there. They slowly migrate across the room. How can this happen? Is the cat doing it to drive us crazy? (She would if she thought it would work!) No, the cat is not involved. The movement is due to the interaction between the carpet and the rugs.

Cooling Fans

This experiment came from Diane in South-central Pennsylvania. She and her son were discussing ceiling fans, and how they make you feel cooler. They wanted to know if the fan actually cools the room, or does it just feel that way?
