The Tamiya 70163 Submarine Motor with Float gives a direct introduction to how motors and buoyancy interact. Built for hands-on learning, the kit helps students and hobbyists put scientific ideas into practice by assembling and testing the unit in water.
Inside the package you will find a compact submarine motor and a polystyrene float. The motor is supplied as a user-assembled item so learners can inspect moving parts, and the float measures 170x100 mm to provide a steady testing platform on water.
This product is useful for guided classroom activities or home experiments. It uses one R6/AA/UM3 battery (not included) for power and works well for demonstrations that show the link between thrust and floatation.
