Giant Sidewalk Chalk Spirograph

Invented in the 1960s by British engineer Denys Fisher, the spirograph was a creative marriage of geometry and art that let people of all ages produce mind-bending patterns* with simple plastic gears. The classic drawing toy has been reimagined and super-sized for outdoor use with sidewalk chalk, so kids can create colorful, geometric wheels, spirals, flowers, and more on any even, smooth surface. Simply snap together the giant ring, place the drawing gear inside, insert chalk into the desired slot, and let the creativity flow.

• Set includes giant ring (eight pieces), a drawing gear, and three pieces of sidewalk chalk.
• For best results, kids should kneel on the outside edge of the ring to keep it in place and use on a smooth outdoor surface like a sidewalk.
• Helps kids practice fine motor skills, learn patterns and geometry, and promotes creativity outside.
• Measures 2.5"L x 12"W x 12"H.
• Ages 6+.
• Made in China.

*Uncommon Knowledge: The geometric patterns created by spriographs are known as hypotrochoids (drawing using the inside of the ring) and epitrochoids (drawing using the outside of the ring).
