Paying attention?

I think this is a video that has to be seen without comment...

I liked the gorilla sitting in the background. That's a reference to another study on perception. For this one, the idea is to count how many times the ball is passed between the team wearing white.

Of course, having just seen the first video you may not see the full effect of the second. But just in case... if you didn't see anything unusual, then try again without the counting.
