I came across an interesting observation experiment the other day, which I want to share with you.

There’s a video on this page, embedded in a 7MB Java applet – so it takes a while to load. The idea is to watch the video, and count how many times a basketball is passed between two players who are both wearing white t-shirts. You may have to concentrate quite hard. Then, watch the video again and count how many times a basketball is passed between two players who are both wearing black t-shirts.

Email me with your counts, and any other comments you have on the video. Please don’t post counts or other information in the comments, so everyone can have a go.
