Gav and Dan, the Slow Mo Guys, have played with dangerous things before, but they are serious when they warn us about playing with large Neodymium magnets. "They will crush you." But that's exactly what they are doing in their latest video. These magnets are so attractive that you can't work with them before removing all the metal on your body, or you'll be sorry. Getting two of them together is another level- they will rush together so quickly and forcefully that they break! It happens in a blink of an eye, but these are the Slow Mo Guys. They recorded magnets coming together at 187,000 frames per second, so we can see how it happens. The collision throw parts if the magnets off, but they are quickly sucked back together. That all occurs in the first four minutes; then they try some other experiments and show us how very weird these magnets act when they're trying to handle them. (via Born in Space)
