Can your marble
make all
three turns?

Start small. Count the successful finishes. Let each builder choose one thing to change, then test the run again.

Bonus twist: Can you make the same run work with a lower starting point?

STARTER CHALLENGE20 MINUTES

The three-turn
trick shot

Can you get a marble into a cup after three changes of direction?

  1. Build a track with three turns. Start with a low, stable base.
  2. Place a cup at the finish. Roll the same marble five times.
  3. Change one thing. Can you beat your first score?
Use an age-appropriate kit and adult supervision. Small marbles are a choking hazard; keep them away from children under 3.

Keep the good times rolling.
