Tell if an egg is raw or boiled with Krampf

How to tell if an egg is raw or boiled with Krampf You can easily tell if an egg is raw or hard boiled without breaking the shell, as long as you know a little science. This experiment uses physics to show how if you spin an egg you can tell if it's insides are viscous or solid! Thanks Happy Scientist Robert Krampf for this great tutorial on the science of eggs and physics of rotation.
