Create an endless array of colorful, swirling shapes with this fun kit that combines math and art.

Yes, you heard right, math and art. A hypotrochoid is the mathematical term for a line traced by a fixed point in a circle (your pen) rolling around a bigger circle. Fascinating and beautiful, these precise patterns are easy to make and can vary wildly by just moving your pen to a different point in the circle.

Includes: 2 hypotrochoid templates, each with three gears, plus red, green and blue pens. Made in China.

WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.
