You may find it weird, but it's not actually.
Just an old simple trick will do. As easy as you may think.
So what shall we do?
Believe it or not, just spin the egg. You heard it right, "SPIN THE EGG!"
But which is which, upon spinning?
The hardboiled egg will spin fast, and can rise up for a few seconds on one end as it spins.
The raw one, spin slow, or can't even spin, at same force applied.
As simple as that.
Won't believe? See for yourself, and be amazed!
Practical information, there is one about floating also but I dont remember now what is it used for.
