Materials Required:
l Raw egg
l Hard-boiled egg
Procedure:
Can you tell the difference between a raw egg and a hard-boiled egg? They look and feel the same, but here is an easy trick.
- Spin a raw egg on a hard surface, such as a counter or tabletop. (Don’t let it fall off the table or you’ll have quite a mess to clean up!) The egg will slow down very soon and move in a floppy, random fashion.
- Now spin a hard-boiled egg. The egg acts quite differently this time. It will spin easily and may stand up on end. You will also notice that it spins for a much longer period of time.
This Is What Happens:
The hard-boiled egg is of nearly uniform density throughout its interior. The raw egg, on the other hand, has a loose, runny composition, and the shifting contents slow down the motion of the egg.
