Tamiya 70154 Submarine Motor with Boat STEM Learning Kit  [70154]

Tamiya 70154 Submarine Motor with Boat - Practical STEM Build

The Tamiya 70154 Submarine Motor with Boat is a straightforward kit aimed at introducing basic mechanical and electrical ideas. It gives a hands-on route to explore propulsion, buoyancy and simple machine concepts by building and testing a small motorised hull.

Essential Features and Learning Points

The kit includes a compact submarine motor that fastens to the supplied polystyrene boat hull via a suction cup. The hull is easy to paint and modify, letting builders personalise the craft while learning assembly skills. Running the motor shows real-world examples of thrust and energy conversion.

How It Helps With STEM Learning

Tamiya 70154 works from a single R6/AA/UM3 battery (not included), demonstrating basic electrical power and propulsion in water. It is suitable for hobbyists, classroom demonstrations, or parents guiding a practical science activity.
