Hi guys... Can u take up this Challenge If u are confident, check your Power of Concentration Concentrate "ONLY ON THE TENNIS BALL " for 30 Seconds ..... . . . . . . . . . . . . . . . . . . . . . [

I think this is a test for men... Rather than look at the ball on the right you will look at the [b]ball[/b] on the left. Anyway I managed but kinda hurts the eyes.
