6. Paper Pinwheels

Pinwheels combine art with a bit of science — they’re colorful, interactive, and fun to watch spin in the breeze.

How to Make:

  • Cut a square piece of colorful paper.
  • Fold diagonally both ways and cut halfway along each line.
  • Bring every other corner to the center and secure with a pushpin and straw.

Design Tips:

  • Use double-sided paper for a vibrant look.
  • Decorate with glitter, stickers, or shapes before assembling.
