This toy boat is based on the principles of buoyancy and basic fluid mechanics, teaching a child the basicsĀ of how a boat works. The toy is made of all plastic and contains a gearbox. The child will interact with the toy by turning the small crank on the outside of the boat, which will activate the gearbox and turn the propellors, moving the boat over the water. The toy is designed for ages 3 and up, as it is fairly simple and there are no small parts.
