Product Description
Set of four Reuleaux triangles that can be used as free wheels or rollers for math classroom demonstrations.  Each wheel is hollow and about 1 cm thick and 3 cm in diameter. They are looped on a thin ring that can be cut away and discarded.

Reuleaux triangles are curves of constant width.  Set the four rollers on a flat surface and line them up like the wheels of a car.  Then place a large flat book on top of them.  Roll the book over the rollers and notice that the book stays at a constant height, just as if it were rolling on a set of four cylindrical wheels.
