Answer 2

X-ray them.

Shake them?

Answer 3

Roll it up on flat surface if it was rolling fast it would be hard boiled egg ...If it was rolling slowly that would be a fresh egg

Answer 4

spin it. they spin differently. boiled spin on the ends and fresh egg spins on its side.

Answer 5

You don't need to build anything.  If you spin the eggs, the hard-boiled egg spins really fast while the fresh egg will spin much slower...liquid versus solid.

Or

You can hold both eggs up to a strong light.  The fresh egg will let some light through whilst the hard boiled will not

Answer 6

You can spin a hard boiled egg but you cannot spin a fresh egg.

Answer 7

I believe if you shine a strong light into a raw or fresh egg, you will have an image of the inside, and it will show as somewhat yellow.  With a hard boiled egg, you shouldn't have any light passing through it.

Aside from that, I don't know if there are any other ways of telling.  Shaking them, maybe?

HTH

Answer 8

Lie it on it's side and spin it.

A fresh egg is hard to spin.

A boiled egg spins freely.
