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.

Bread Bubbles

This experiment is about bread. If you have used my website for long, you know that I like experiments with food, especially when it is tasty food. We regularly bake bread, and there are few smells that are better than the smell of freshly baked bread.

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.
