Magnetic paint
Magnetic Paint turns any paintable surface into a magnetic playland. Infused with iron dust, this magnetic paint is a gray latex paint that works as a primer that attracts magnets (the paint is not itself a magnet, it attracts magnets). It is child safe and non toxic, and is completely safe to use near computers, since the paint attracts magnets but is not itself a magnet.
