Your missions

  1. Mission 1 of 4

    Left or right?

    • Paper + pencil

    At the marble divider, guess which way each marble will go. Tally 20 marbles. Is it close to half and half?

  2. Mission 2 of 4

    Slow motion

    • Phone camera

    Film one run in slow motion on a phone. Where is the marble fastest? Where does it slow down?

  3. Mission 3 of 4

    Ears only

    • 2 players

    One player closes their eyes and calls out where the marble is from the sound alone.

  4. Mission 4 of 4

    Kitchen extension

    • Tubes + books
    • A bowl

    Build a short extra run from paper towel tubes and books that ends in a bowl. Can a marble go from your run into the city?

Safety first: Keep the marbles away from little ones under 3.
