Why do you put eggs in a basin full of water to know if it is fresh or old?

Because - the boiled egg will be solid inside - and will stop if you touch (and release) it while it's spinning. The raw egg will carry on spinning after you take your finger off it - as the fluid inside keeps moving.

∙ 12y agoThis is called the float test. Old eggs will develop an air pocket within the shell. This is because eggs are porous and moisture escapes from inside. The moisture is replaced by air. The older the egg the larger the air pocket and the more it will float. Eggs that stay on the bottom of the bowl are still fresh. Eggs that stay mostly on the bottom but "stand up" at either end are still useable but should be used within a few days. Eggs that float to the surface of the bowel of water should be carefully thrown away. It would not be a good idea to break them, they will smell very bad.
