Magnetic Spinning Gears
Our amazing building set lets kids create their own spectacular, spinning shows! The interchangeable pieces slide together easily for no-fail designing. Children simply stick the gears onto a magnetic surface, connecting them any way they like...then turn one of the built-in handles to set the whole interlocking creation in motion! Sturdy plastic set consists of 22 magnetic gears in two sizes. Large gears measure 3 3?4".
