When you play golf, it can become tiresome to bend over 18 times a game to retrieve your golf ball from the cup. Here is my idea: The cup could have a small air cartridge inside that is activated by a small hand held device the players have and could only be triggered from a five foot radius. The air cartridge would only have sufficient air to launch the golf ball three feet into the air and then the golfer then can retrieve his/her golf ball from midair instead of bending over 18 times a game.
