A pencil, a shoe and a folded map each have one secret spot where they sit still on a single finger. Two fingers sliding together always find it, wherever you start.

What you need

  • Pencil or pen
  • Folded map or magazine
  • Shoe
  • Bottle

How to play

  1. Rest a pencil across two outstretched index fingers held far apart.
  2. Slide your fingers slowly toward each other until they meet.
  3. Notice that they meet under the same spot however far apart you began.
  4. Balance the pencil on one finger there and let your child see it hold.
  5. Repeat with a magazine, a shoe and a bottle, guessing the point in advance each time.
