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 plastic wheel to the wire frame, allowing it to twirl along the track seemingly by magic. Tilt the wire frame to make the twirler spin faster. Watch the twirler twist and turn for hours of imaginative fun. Recommended for ages 5 years and up.
