- Toy is based on rotation, buoyancy, and propulsion.
- Designed for ages 4-12.
- The top is placed in the “launcher” and the ejection handle is depressed. This spins the top rapidly and releases it from the launcher. It is held over bathwater or a sink and spins on top of the water until it loses its speed and sinks.
- Toy is safe because no small parts and nothing pointy.
- Cost is pretty low because of all cheap plastic parts. No electronics.
