Pringles cans have a wide variety of uses, but this one is special: Instructables user Cats Science Club has a guide to making a Pringles can mini-oven, so the fun really never does have to stop.

Once you’ve munched all of the identically-shaped chips, all you need is a wooden skewer and a hot-glue gun. The mini-oven cooks using solar power and the user that posted the guide says it reached temperatures near 75 degrees C on a sunny day. You can even put some plastic over the opening to allow light in while keeping heat in. Don’t let those Pringles cans go to waste this summer — there are hot dogs to cook!
