Build once, tinker forever — no tools needed! After constructing the gears and pulleys, kids can continue to play and answer every question they have about how things work. For extra fun, put paper or clay creations on top of gears and watch them move around!
- Each kit includes 8 gears (2 each of 4 sizes), 8 pulleys (2 each of 4 sizes), 4 perpendicular blocks, 2 hole plates, 4 dowels and 10 rubber bands
- A variety of build guides and design challenges are available for free download
- Ages 4+ (adult supervision recommended)
