Don't throw out chips or other snacks because they're stale.
Turn on the oven to about 300 degrees. Put the chips (Bugles in my case today) on a cookie sheet and spread them out. Put the sheet in the oven for a few minutes, then turn off the oven. Leave the cookie sheet in the oven where it's dry and warm til the snack is revived and dry and nice and crunchy!
I do this all the time with tortilla chips from restaurants. Sometimes they're even better when I'm done with them.
