Flying Circus of Physics: Eggs & Angular Momentum (Episode 1.4)

Next time you want to determine if an egg is hard-boiled or fresh, give it a spin! A hard-boiled egg spins stably because it’s solid and its angular momentum is conserved. A fresh egg spins erratically because it’s filled with fluids that slosh randomly. Professor Jearl Walker of Cleveland State University will attempt to demonstrate -- but we can’t promise he won’t end up with egg all over his face. STAY CONNECTED: TO APPLY:
