Magnetic putty eats rare earth neodynium

This time-lapse video shows 3.2 ounces of putty encompassing a magnet in 10 minutes. The special putty is infused with more than a million iron-based particles. How this works is that this wonderful silicone substance takes on the properties of a magnet itself when placed in close contact with the strong Neodymium magnet. This causes the appearance of the magnet being engulfed by the silver goo. This is a great way to introduce kids to science and the study of magnetism.

For those who like details: the 10-minute segment is compressed to less than 2 minutes of High Definition (HD) film. The putty brand used is Crazy Aaron’s Thinking Putty — Quick Silver edition purchased through Shot with a Canon 60d and Sigma lens at 30 fps then edited with Final Cut Pro X. The staging was done with a simple theater flood light directed through glazed white glass plate.
