Bag of chips
There aren't a lot of reasons to shrink a bag of chips unless you're looking for something cool to do, want a small bag for your Barbie to play with, or want an accessory for your doll house. The small words, like the Ingredients list, are still legible on the bag after shrinking. It could be dangerous to shrink a bag of chips, so if you're not an adult, make sure you get parental permission and have adult supervision before doing this.
Get a plastic-type chip bag of any size. A smaller-sized bag will shrink to the smallest size possible.
Eat the chips or empty them into a baggy or storage container. Make sure all crumbs are removed.
Wipe the inside of the bag with a paper towel to remove the oil and salt. Oil left in the bag can cause bumps in the bag after shrinking.
Turn on an exhaust fan to remove gases that may be emitted from the bag when it's heated. Keep infants or small children away from the area.
Put the bag on a baking sheet and place it on the middle rack of your oven. Remove any racks above it to get better heat exposure. Set the oven to broil.
Watch the bag while it's heating with the oven door partially open to make sure it doesn't catch on fire. If it does, close the oven door and turn the oven off. Keep the oven door closed so the fire can extinguish itself from lack of oxygen.
Use tongs to turn the bag over and remove it after it is done shrinking. Don't touch it while it's still hot.
Keep a fire extinguisher close by in case things get out of hand and know how to use it. Kids shouldn't do this without parental or adult supervision.
