Revolution

Item # 758553

Magic? Anti-gravity? No. Strong repelling magnets. Place the metal tip against the glass, then spin the axle. The friction point between the tip and glass helps the floating axle rotate for several minutes. Stimulate conversations about forces, perpetual motion, magnetism, or mechanics. For a light and optics demo, use a stroboscope to make the axle’s rotational direction appear to go in reverse. Assembled size (with glass), 5-1/2 x 3-1/5 x 2-7/10” H. No batteries needed. Includes instructions.

Demonstrate physics principles in any science classroom. Stimulate critical-thinking skills as students try to figure out why the axle spins. Then challenge students to see how long they can keep the axle spinning. Extend the demo to discuss real-world applications of repelling magnets (magnetic trains) or the concept of perpetual motion machines.

Note: Contains strong magnets. Keep away from computers and other items that may be sensitive to magnetic fields.

Assembled size (with glass), 5-1/2 x 3-1/5 x 2-7/10” H. No batteries needed. Includes instructions.
