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