From the outside a raw egg and a hard boiled egg look the same, so how can you tell the difference?
How can you tell if an egg is raw or hard boiled?
The key is in the spin! A hard boiled egg will spin nicely and a raw egg will wobble.
The raw egg is full of fluid which moves around as it spins making the egg wobble!
