Spin the egg! If the egg is raw it will wobble, because it's still liquid inside, if it's hard boiled it will spin on it's end, because it's solid.
if you spin it and put your finger on the hard boiled egg it would stop
boiled egg
Spin the egg on a flat surface, a raw egg will wobble as the contents are liquid, a soft boiled egg will try to stand up, and a hard boiled egg will stand up and spin without wobbling as it is solid inside.
Put the on a flat surface, then give each egg a quick spin. Hard boiled eggs should keep spinning for a longer time. This happens because the interior of the egg is solid, while in the uncooked eggs the liquid inside sloshes around, slowing the egg.
Spin it on a table. The boiled egg will keep spinning since it is solid. The raw egg will not spin much since the solid shell is spinning while the liquid inside is not.
A hard boiled egg is cooked until solid all the way through, a normal 'soft' boiled egg the centre yolk will still be runny, To test the egg you need to do is spin the egg on a flat surface, if the egg is soft boiled it will wobble because part of the egg is still liquid, if it is hard boiled it will spin on end, because the contents are solid.
The raw egg has fluid inside and it wobbles when you spin it but a boiled egg is solid and it doesn't wobble so much as the raw egg
When you can spin it like a top on one end. An uncooked egg will not continue to spin due to the liquid in it. A hard boiled egg WILL continue to spin due to more of a solid internal mass.
I'm not sure what you mean by this. A hard boiled egg will spin faster and roll farther, if that's what you mean.
the yolk,the heavier part of the egg would have coagulated into a solid core in the centre,lowering the centre of gravity of the egg,and hence decreasing the inertia of its rotational moment..hence it spins better when hard-boiled
For hard-boiled eggs:Eggs are boiled enough if their yolk is firm and bright yellow. They are boiled too much if the yolk develops a greenish-grey membrane.Submerge them in a pot of water and bring it to a boil on the stove. Once the water is boiling, turn off the burner, stick a lid on the pot and let it sit for 15 minutes. Then, drain the water, rinse the eggs in cold water, and refrigerate. They'll be perfectly cooked every time. No need to make guesses.You can tell if an egg is hard-boiled by spinning it long-ways-up on a counter top. If it stays up and spins, it's boiled. If it falls, it's not.Another way to know if it's boiled:Get a cup and put water in it then put the egg in it, the egg will float if boiled and sink if raw.
