If you haven't seen the perception film, read these instructions first...
(If you have seen it, scroll down to the bottom of the page)
When you click on the basketball image below, you'll be taken to a page which loads a short film. In the film there are three people wearing white t-shirts, passing a basketball around.
Your task is to count the number of passes.
It's not that easy, of course. There are three other people, wearing black t-shirts, and they're passing their own basketball.
IGNORE the passes of the people in the black t-shirts: count only the passes of the people in the white t-shirts.
Once you've finished, come back to this page, and then click on the link lower down, to find out if the number of passes you counted was correct. (Don't go to the page before watching the film, obviously...)
