Christo asks:

"My daughter wants to know what egg will get the hottest. One in a closed clear glass box or one in a black box? Both in sun."

Who can help?

A brilliant question! And sadly, it all depends on what you mean by "black"!

[Bored chemist]

It also depends on whether the egg is white, brown or golden.
Does anyone know if an egg shell is strong enough to survive in a vacuum chamber?
