Curious kids can explore the fascinating world of physics by building their own "perpetual motion machine" powered by an invisible magnetic field. This hands-on perpetual motion toy demonstrates the principles of electromagnetism and kinetic energy, sparking curiosity about the forces that keep objects in motion.

The kit includes all necessary components, along with a color poster and full instructions. A fun and educational STEM activity, Smithsonian's "Perpetual" Motion Machine Kit is perfect for young scientists eager to experiment and learn.
