Learn the mysteries of Infrared Light and build a useful kit while you're at it. If you've ever walked into a convenience store and heard the door bell as you walked thru, you likely passed through an infrared beam that when broken, sounded a chime. You can use this on your pet door, refrigerator or somewhere where you'd want to know when someone or something passed by.
