An EGGSellent Situation
Science brain teasers require understanding of the physical or biological world and the laws that govern it.
A man has two eggs. One is raw and the other is boiled. He would like to eat the boiled egg for lunch and save the raw one to have for breakfast the next morning. How can he find the boiled egg without breaking the wrong egg by mistake?
HintRound and round we go, what's the answer, someone must know!
If the man spins the eggs on a flat surface, the hardboiled egg will spin more smoothly than the raw egg. The raw egg will wobble when spun.

|The question says boiled egg, not hard boiled. A boiled egg will have the same effect as a raw egg.|

|beelezebub, the implication is obvious; i think that it is fine to point out errors or other possible solutions, but nit-picking such minor points enhances neither the puzzle nor the solution.|

|I use the spin system with my eggs all the time. Works great. Another effect that you can see with the raw egg is when you spin it along its short axis, not the long axis like a top, and stop it from spinning by quickly touching the top of the egg and then removing your hand then it will start spinning again while a hard boiled egg will stay stopped. The liquid in the raw egg is still spinning around for a moment even after you stop the eggs spin. That is why is starts spinning again. Hope someone could follow all that.|

|I guessed that the boiled egg would be hot|

|I say you yell at the eggs. The echo from the two eggs will be slightly different, and should be noticable.|

|I'm with elctronjohn on this.|
I have heard this before and the more important point to me, is that if you stop a hardboiled egg from spinning its innards lose momentum, whereas if you do the same with a raw egg only the shell stops, so the innards keep moving.

|my grandma taught me that! |
but i never knew that think about how it starts spinning again, that's cool!

|I knew this! I "egg"ree that it's not fascinating and should indicate hard boiled, but not bad|

|I thought there would be a weight difference... |

|I thought one would float, and one would sink in water, but I didn't know which would be which.|

|The hard boiled egg would also have a shell that if a little pressure is applied it'll peel off. Good teaser and when I read through it it does make sense the egg would wobble. |
