Made with micron-sized, iron-based particles distributed throughout, the astonishing, moldable magnetic putty takes on the properties of a magnet itself when placed in close contact with the included magnet. It’s perfect for science-loving kids, or for any adult that loves intelligent play! Use the magnet to do the “snake charmer” trick or leave the magnet on your ball of putty and watch it completely engulf the magnet in minutes! Comes with a Teacher’s Guide.
