Hot enough to fry an egg

This is how hot it is in Australia's capital city right now. But, is it hot enough to fry an egg on the sidewalk?

In cooking terms, an egg needs a temperature of 158F to cook, and most sidewalks do not get up to that temperature. The egg, when cracked open on the cement, cools it down. Black macadam sidewalks are hotter than gray ones, and using metal as well, can raise the temperature. So you could try using aluminium foil on top of the sidewalk surface.

And lastly, you can place a pane of glass under a frypan, on top of the sidewalk or cement. For good measure, you can place another pane of glass on top of egg in the frypan.

Now, another way to try to cook an egg, is on the bonnet of a car that has been outside on a very hot day. Don't use a teacher's car, you're likely to get detention.
