Egg Experiment to Demonstrate Inertia
Veritasium - Season 2011
DESCRIPTION
If you spin a raw egg and then stop it, it will start spinning again without you having to touch it. A boiled egg, on the other hand, stops and stays stopped. Why is this? Well, a raw egg contains a yolk that moves inside the egg independently of the shell. If you stop the shell, the yolk inside continues to move due to its inertia and it, therefore, gets the egg spinning again.
