Flashing golf balls
The twilight tracer golf balls have all the required functionality of a conventional ball (feel, accuracy, distance, regulation size and weight, etc.) and look exactly like a normal ball. That is until you hit it, where upon it changes from a boring white dimpled ball to an all singing red flashing flying sphere. The flashing effect lasts for 5 minutes, so that you can still find the ball after a leisurely stroll.
