Perpetual Motion Machine Kit – Explore Magnet Power & Real Science

Discover the science behind “perpetual motion” with this hands-on kit that lets kids build a motion machine powered by an invisible magnetic field! While true perpetual motion isn’t possible without an external energy source, this engaging STEM set helps young scientists understand why—and guides them through creating motion machines that demonstrate the real principles behind the idea.

Explore how magnets, energy, and the Laws of Thermodynamics work together, and uncover why scientists and engineers have never been able to create a machine that runs forever on its own.

Inside the Kit, Kids Will Learn:

  • How batteries generate the magnetic force that keeps the machine moving

  • The basics of the First and Second Laws of Thermodynamics

  • Why real perpetual motion devices don’t work—and what makes this one go

Perfect for curious builders and budding inventors, this kit delivers hands-on experimentation and big “aha!” moments.

Requires: 4 AA (1.5V) batteries (not included)
Ages: 8+
