Magnet Collisions

This is a very "attractive" video. Let's see what happens when a large magnet meets a group of smaller magnets -in slow motion. It's fascinating to see the different reactions depending on the size and configurations of the magnets. And the slow motion is crucial, because in real time it happens in the blink of an eye, which is no fun. We get a glimpse of that at the end. (via Laughing Squid)
