Magnetic Thinking Putty Wants Your Loose Change

Illustration for article titled Magnetic Thinking Putty Wants Your Loose Change

Shall we open with an ironic reference to Terminator 2? Best not. That's the easy option, especially when dealing with lumps of metallic ooze that seem able to alter their shape in response to their surroundings.


Magnetic Thinking Putty is your standard play putty, only stuffed with "millions of tiny micron-sized magnets" to ensure it responds to any other large magnet. Including the one that comes in the box. Here's a video of Magnetic Silly Putty absorbing its cubed magnet. It doesn't move quite as fast as Robert Patrick sprinting after your car.

OK. It sounded cool when I read "millions of tiny micron-sized magnets", but watching the video it's clear it's no magnet but instead just ferromagnetic material suspended in a malleable putty, i.e. it isn't magnetized on its own:

- it won't attract other ferromagnetic materials by itself, and

- it can't show repulsion towards other magnets, whatever the polarity.

It isn't a magnet after all, and even then, there's no way you could align the particles to form poles, unless maybe if you submit it to a (very) strong magnetic field.
