Teach children about the invisible power of magnetism with the Toysmith® retro magic rail twirler. The magic rail twirler is a reproduction of a classic retro toy using magnets to allow a spinning wheel to perform gravity-defying stunts. Magnets adhere the wheel to the frame, allowing it to twirl along the track seemingly by magic. Tilt the frame to make the twirler spin faster. Watch the twirler twist and turn for hours of imaginative fun. Details: Multicolor 13" x 1.25" x 4.25" package size Plastic, magnets and wire For ages 5 and up
