Video: Watch this demo

Description: The diameter of the circular wheel is equal to the radii of the three arcs that make up the awkwardly-shaped wheel,
thus the distance from the ground to the board is always a constant on both wheels, and it rolls along just fine.

Equipment:

  • Long board
  • Circular wheel
  • Awkwardly-shaped wheel

Setup Procedure:

  1. Make sure the wheels are firmly attached to the axles and the awkwardly-shaped wheel has both wheels aligned to the same orientation (points going in same directions).

Demonstration Procedure:

  1. Place board on top of one circular wheel and one awkwardly-shaped wheel, and roll it over the top of them!
