A Great Science Project for a Rainy Day
Rainy days are perfect for learning new things. For example, try this science project that shows how water and color can travel when given the right tools. You only need 3 different types of items. The kitchen is the best place to work. Be sure and clean up your mess when you are finished.
You will need:
5 Clear Drinking Glasses
4 Paper Towels
3 Different Colors Food Dye
Set the drinking glasses side by side. Fill the 1st, 3rd and 5th glass 3/4 full with water. Leave the 2nd and 4th empty.
Place 3-4 drops of dye in the 1st glass filled with water. Repeat for the 3rd and 5th, using a different color dye for each.
Take one paper towel and fold longway. Fold it again until it is about one inch thick, then crease it in the middle so that it stands up like an upside down V. Repeat with the other 3 paper towels.
Place one upside down paper towel V in the first and second glass. One end will be in the first glass and the other end will be in the second glass. Take another upside down V and place one end in the second and third glass. Repeat until all glasses are sharing a V.
Watch as the paper towels share the water and the color with the 2 empty glasses and change color along the way.
Can you explain how this happens?
