Rainbow Paper

Learn the science of light with a simple and beautiful experiment in which you can make a rainbow right in your own home. White light, like sunlight, is made up of all the colors of the rainbow combined. When that light enters a raindrop in the sky, or the nail polish in this experiment, the different colors separate out to form the rainbow pattern that you see. Can you find all the colors of the rainbow in your nail polish paper?

Walking Water

Watch as water travels on its own against gravity with the power of capillary action. Capillary action occurs here because the adhesive force between the water and the paper towel is greater than the force of gravity pulling the water down. Now use some food coloring to mix colors through your walking water!

Treasure Grab

With just a straw, a piece of stiff paper, a magnet, and some string, you can make your own sliding treasure grabber! Because of the angled straws, you can control the amount of friction on the string and make the string slide and stop to grab magnetic treasure. Just drop some small metal objects on the floor and use the slider to pick them up!

Streaky Paper

It's art time with a hint of science! Create streaky paper with chalk that sticks to it! How does it happen? The oil mixed into the chalk has molecules that stick to the paper along with the help of water mixed with vinegar.
