If you’re tired of standing over the grill, or just want a cool project to impress your friends, here’s one for your next cookout. Try making a solar oven out of a Pringles can, and use it to cook your hot dogs.

We can’t answer why you’d want to use a contraption like this, but we can definitely show you how. Take a cylindrical container, cut out a rectangle from the sides, drill a hole through the bottom of the can, then poke a skewer through the can. Skewer your dogs, set the can up on an unheated grill (or table, lawn, or flat surface) and get cooking.

The creators (Cats Science Club) of the “solar oven” claim that the device can reach up to 170 F on a hot sunny day. We’re not so sure, but then again, we’ll leave that to you guys. Please let us know any success (or horror) stories, and tell us whether this really works, or just results in lukewarm hot dogs.
