Do your kids finish all the milk in their bowl of cereal? If not, you can put that milk to good use and teach your kids some science.
What you need
- food coloring in different shades
- liquid dish soap
- Q-tip (optional)
What to do
- Pour milk on a dinner plate. (I get my kids to transfer it out with a spoon. Good practice for pouring and coordination).
- Add food coloring – one drop of each. Option #1: right in the center of the plate and keep the drops close together. Option #2: one drop of each color on each side of the plate.
- Touch the tip of a Q-tip in the middle of the color blob in the middle of the milk. If don’t have a Q-tip, use a finger. Don’t stir the mix!!
Did anything happen?
- Now soak a fresh Q-tip in liquid dish soap. (If you don’t have a Q-tip, dig a finger into the soup). Place the soapy end of a Q-tip (or your finger) in the middle of your plate of milk and hold it there 10-15 seconds. Don’t stir!
What is happening?
Is milk started moving around!?
Soak another Q-tip in liquid dish soap and place it in a different place in the milk. Do you see a beautiful burst of color? And how exciting is it that milk continues to move even after Q-tip is removed.
