Water Bottle Rocket
Why do rockets propelled by air pressure work better with water inside, and how much water works best?

Polarized Light
Passing light through a polarizing filter gives it intriguing properties that are exploited all around us, particularly in the LCD screens we see on our laptops and other electronic devices.

Storing an Electric Charge
Capacitors are used to store an electric charge for quick release. They are common components of electronic devices, but they need to be treated carefully, because they can release a considerable jolt of electricity!

Make a Comet
It’s simple and fun to make your own dirty snowball and, in the process, learn what comet are composed of and how they move through space!

Measuring the Speed of Light With a Microwave
The electromagnetic waves in a microwave travel at the speed of light. Figuring out their wavelength will give us a tasty approximation of the speed of light!

Making Curds and Whey
Step one in cheesemaking is acidifying the milk to separate curds (which become cheese) and liquid whey (water, proteins, and other stuff).
