Here's the most insane golf shot you'll EVER see ... Jordan Spieth skipped a ball SEVEN times over the water in a pond -- and landed it within 10 feet from the hole!
It all went down Wednesday at The Par 3 Contest -- the prelude to this weekend's Masters tournament -- where pros are known to take it easy before they tee it up for real on Thursday at Augusta.
Jordan decided to put on a little show for fans ... heading down to the water for one of his tee shots -- and hitting a shot that required the ball to skip across the pond's water.
