It stretches. It bounces. It tears and it shatters – now put it next to a magnet and it comes alive!

Of course you remember playing with Silly Putty as a kid. Thinking Putty, however, is no longer just Silly; it’s all grown up and developed even more superpowers! Thinking Putty is a silicone polymer-based children’s toy that carries the same unique properties of Silly Putty: it is viscoelastic, meaning it can be stretched and shaped and mashed back together again.

But, what’s this magnetic component of the Thinking Putty we’re talking about you may ask?

The Thinking Putty is loaded with micron-sized iron-based particles distributed throughout. The astonishingly moldable Thinking Putty takes on the properties of a magnet itself when placed in close contact with the included Neodymium Iron Boron magnet. Put it near the magnet and within five seconds, the putty will stretch itself out to reach the magnet almost as if it were alive. Press the magnet into it and the whole piece of putty becomes magnetic, able to lift tacks and paperclips on its own after charging in a magnetic field.

This awesome phenomenon allows you to control the Thinking Putty like a snake charmer. Hours of fun are guaranteed or if you’re at work something to fidget with in front of the monitor. Now be the envy of all your friends at work.

Imbibing all the properties of a magnet, it even repels from another mound of Thinking Putty’s magnetic field. Another new feature of this multi-functional toy is that you now have the ability to smash it into a dozen pieces with a hammer. Don’t try this without safety goggles! Awesome!

Over long time intervals, it acts somewhat like a liquid (spreading slowly). Over medium time intervals, it stretches. Over quick time intervals, you can tear it. And when pounded with a hammer, it acts like a solid and shatters. In a large clean area, you can collect all of the pieces and continue to use the putty as if nothing happened.


Proudly made in Pennsylvania USA, Crazy Aaron’s Magnetic Thinking Putty is the perfect gift 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 engulf that magnet in about an hour! What can you do with it? The possibilities are endless!

For those who prefer to make their own (although be forewarned that this method may leave some dark residue on light surfaces), there is a magnetic Silly Putty project over on Instructables:
