Very cool! When you increase the speed the ball breaks to the right, when slowed down it breaks to the left. Increase the spin and it flies straight, slow it down and it breaks more.

I remember reading years ago in LIFE magazine that a curve ball was just an illusion. I've faced my share of good pitchers (my Brother included) and I swear it ain't no illusion! Dat shyt drops off a table!

It is one of things that makes you wonder how much you see is real.



This is one of my favorites. The square A just looks darker than B yet they are 100% the same. You can take it into PhotoShop and measure the squares, and they are the same. I printed that image on a high quality printer. Then I cut the square out and put them side by side. Yep the same.

If you don't have PhotoShop is is had to find a eyedropper tool. I printed it for a guy that would not believe it any other way.
