Does it feel hot enough to fry an egg? Use this solar cooling kit to find out if it really is. Hard to imagine a few pieces of shiny cardboard creating enough heat to cook food – especially when you aren’t lighting them on fire. But assembled, they make a parabolic cooker. Just add a little mid-day sun and you'll generate enough heat to cook with. Our testers had fun melting chocolate and using it to dip their fruit. But unless perhpas you have perfect conditions, this parabolic cooker didn't get hot enough to actually boil water, or even cook an egg. The small black cookpot did get hot enough to be a brun concern, though, so adult supervision is recommended. Parents noted also that it's shape and small size make it a nuissance to clean. A fun demonstration of the power of green energy, with enough background information to get kids thinking.  Works best on a cloudless, wind-free day.
