EGG TEST
How can a myth buster tell if an egg is fully cooked without actually breaking its shell?

To try this experiment you will need:
-one uncooked egg
-one hard-boiled egg
-an even, hard surface to spin the eggs on

All you need to do is spin the egg. If it is cooked, the egg will spin in an even, circular motion for a while.

If the egg is raw, it will tumble around in an erratic manner and will soon stop moving.

There is a scientific explanation for this. The mass of a cooked egg is evenly distributed inside and that remains unchanged when it’s spun. If the egg is raw, the yolk inside is displaced, causing an uneven distribution of its mass, thus making it spin uncontrollably.

You could also try cooking eggs for varying amounts of time. What happens to an egg that has only been cooked for one minute or three minutes? Try out your own fun myths at home, or swap myths with friends!
