Prepare Your Station
Fill each bottle about 3/4 full with room-temperature water. Lay down a towel or place bottles in a baking sheet for easy cleanup.

Add Primary Colors
Let your child drop 5-8 drops of one color into each bottle. Use one color per bottle initially (Red, Blue, Yellow).

Mix & Watch
Screw the cap on tightly. Have your child shake each bottle gently. Talk about how the color spreads through the water like magic!

Combine Colors
Pour half of the red water into the blue bottle. Pour half of the yellow into the red. Discuss what new colors appear (Purple & Orange!).

Seal & Decorate
Apply clear tape over the caps for safety. Let your child decorate the outside with stickers, markers, or washi tape to create their rainbow collection.
