Clumsy Catching

Enrichment Activity for 5-11 11-14

What you need

  • A cone shaped party hat
  • Scissors
  • A soft ball
  • A friend


  1. Cut the tip off the party hat to make a hole about 2cm in diameter
  2. Wear the hat over your face
  3. Try to play catch with your friend using a soft ball

Results and Explanation

When you’re wearing the hat you can only see with one eye at a time. Without your normal, two-eyed, binocular vision you can’t judge distances as well and it’s much harder to catch the ball.
