It might be tempting to finish off a bag of chips after you open them. After all, if you don't, then they're more likely than not to go stale and taste worse the next time you open the bag. However, finishing an entire bag of chips in one sitting probably isn't the best thing for our health, and there's actually an easy way to keep those chips fresher for longer.
Just fold the two corners of your bag and roll the top backward. This should allow you to fold the flaps and create a seal. And don't forget to squeeze the bag to release as much air as possible.
