Color-mixing bags

From the house

• A zip-lock bag
• Two paint colors, like yellow and blue (or food coloring in hair gel)
• Tape

How to play

1. Squeeze a blob of each color into opposite corners of the bag.
2. Seal it, tape it shut, and tape it flat to a table or window.
3. They squish the colors together. What new color appears?
4. Try another bag with red and yellow.

Fit it to your child

• Easier: Tape the bag to the floor or high-chair tray and let them pat and press it with flat hands.
• Harder: Before squishing, they guess the new color, then try red and blue to make purple.

Words to use

• squish
• mix
• yellow
• blue
• green

Why it helps

Squishing two colors together and seeing a brand-new one appear is cause and effect they make happen themselves, with zero mess.
