Ferromagnetic particles in the putty are strongly attracted to the magnet and very slowly engulf the surface of the magnet. The magnet is a strong neodymium iron boron magnet. It's a very powerful magnet for its size and could erase magnetic stripes found in credit cards and damage electronics.via

Slo-Mo Photography at 1 trillion frames per second
Ramesh Raskar presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look “around” corners or see inside the body without X-rays.via
