Description
Build your own so-called "perpetual motion" machine and explore why true perpetual motion remains impossible—at least according to the laws of physics. Once assembled, this cool desktop gadget seems to spin endlessly, powered by an invisible magnetic field. It's a great way to spark curiosity about motion, energy, and why some inventions are more thought experiment than possibility.
Now in updated packaging—same hands-on STEM activities inside!
