Your missions
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?
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?
Mission 3 of 4
Ears only
- 2 players
One player closes their eyes and calls out where the marble is from the sound alone.
Mission 4 of 4
Kitchen extension
- Kitchen-roll tubes
- Books + a bowl
Build a short extra run from kitchen-roll tubes (or rolled-up newspaper) 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.
