Today we've been shrinking.... snack bags, that is. You eat a tasty snack, i.e. chips, ramen noodles, candy, cookies, and then turn the bag into a kitchy nerdy keychain or backpack charm ! Ok, they're not nearly as cool as all that but they were fun to make for a minute or two. Kids especially think they're fun. Here's how we did it: Heat your oven to 325 degrees. Line a cookie sheet with crumpled tin foil, dull side up. Spray the tin foil with non-stick spray, like Pam. Wash and dry the bag you want to shrink. Place bag onto tin foil lined cookie sheet and place into preheated oven. Watch as the bag shrinks ! Remove from oven and let cool. We rinsed ours in cool water. Punch a hole in the shrunken bag (we used the cropadile) and add a lanyard, ball chain, keyring, etc. **Not all bags shrink. Ones made of foil won't shrink. Watch carefully and remove promptly after shrinking stops.***
