How to tell if an egg is boiled or not
Have you ever tried to peel an egg only to find out that it is raw inside?
Well, there is an easy trick to find out if the egg is boiled or not.
As shown in the below video, place the egg on a flat surface and try to spin it.
Because the interior of a raw egg is liquid, it abstracts the kinetic energy and resists to the movement, so it revolves slowly and stops after a while.
On the contrary, when spinning a boiled egg, because the interior is solid and the shape is aerodynamic and has minimum contact with the surface, it spins fast, almost like a fidget spinner.
Try it, and you will be amazed!
