How hot is it?

You've heard the saying that it's hot enough to fry an egg on the sidewalk? Well today Reagan and I decided to test that theory. First, we did some research. I was pretty sure that it wasn't ACTUALLY hot enough to fry an egg, as the temperature needed has to be a constant 158 F. It's not QUITE that hot here--although Indiana is suffering a major heat wave. The heat index for today is supposed to be 107 degrees!

We started out with our materials: an egg, a piece of aluminum foil (folded up on the sides so the egg doesn't escape!) and a magnifying glass.

Reagan cracked the egg and I showed her how to focus the sun's rays so that it would "cook" the egg.

She did a great job..but it still wasn't enough to actually begin frying the egg.

We gave up after a few minutes and decided to let the sun do it's job. We left it on a level surface in the direct sunlight.

And after an hour, we checked it. Unfortunately the wind had blown our experiment over and the ants were beginning to attack. But if you look just closely enough, you'll see that the egg was actually beginning to coagulate.

Pretty cool, huh? So technically it's not QUITE hot enough to fry an egg on the sidewalk--but it's pretty darn close!
