Lock your keys in the car? Apparently you can retrieve them with a tennis ball. The trick involves drilling or burning a hole in the tennis ball and then using muscle to force enough air pressure into the door to pop the lock. This sure beats messing around with a coat hanger and it gives you a second reason to keep that old tennis ball on your antenna! Thanks, Joe!
