This is a very simple do it yourself project and kids will think it's cool also. This is intended for an audience of tweens, whether it be for a unique key chain of some of your favorite snacks or a quick science project, which is where I first heard of this as a child.

With very little prep work and time you can do this in 10 minutes. So the next time you are eating a bag of crunchy deliciousness don't just throw the bag in the trash, instead shrink it and make people wonder how you did it

Step 1: Things Needed

Bags of chips (empty)
Oven Safe Pan and mitts
Hole Puncher
Keyring

Step 2: Baking and Shrinking

Preheat oven to 325 and place chip bags on the pan, and place in oven.

Let bake/shrink for 4 minutes, or until desired size, being sure to keep checking it

Step 3: Straightening Out

Take pan out of oven ( Caution: Pan and chip bags will be hot, please be careful! )

Let chip bags cool for a minute. Don't let bags cool completely because you need the bags to be warm for shaping purposes. Once straightened out as much as possible, continue to let cool.
