I was reading Dave Barry today,
"The Ballistic Driver is a ''swing-less'' golf club. You grip it as usual, and you position the head of the club next to the golf ball. But instead of swinging the club, you press an ''Activator Button'' on the grip; this detonates a small explosive charge inside the club head, which causes a metal plate to shoot out the side of the club a distance of 1.5 inches at a speed of 200 miles per hour. The plate hits the golf ball, which then, according to the brochure, goes ''250 yards, every time . . . down the middle, exactly where you aimed it, drive after drive."
He goes on to say, "''it could theoretically propel the ball 500 yards.'' This means that a pathetic schlump like me could propel the ball farther than Tiger Woods Inc. hits it on those rare occasions when he is not filming American Express commercials.
And who knows what lies down the road? I mean, if we can make a club that can hit the ball 500 yards, why not 1,000? Why not 1,500? Why not a mile?"
And I wondered, why not a mile? A lot would depend on what kind of propulsion you used, but I'm guessing the muzzle velocity would be supersonic.
