This Thinking Putty has super magnetic properties! It's tougher than the thermochromatic kinds, and has a greenish-black metallic shine to it. This is a great way to explore the properties of magnetism. Kids - and adults! - can spend hours discovering unique characteristics of this putty.
You'll get 1/5 lb (3.2 oz) of putty in a metal tin, plus a strong 1/2" neodymium magnet. This product is non-toxic and is safe for those with latex allergies. Made in the USA.
Some activities to do with your Strange Attractor Thinking Putty and a strong magnet:
- Polar Experiment - Hold the side of the magnet with a repelling charge (hold it to the Thinking Putty to find which side doesn't stick) to a "finger" of the putty. If you have a thin enough section of putty, it will move trying to get to the other side of the magnet - the side it's attracted to. Force it to stay facing the repelling side of the magnet, though. In about 5-20 seconds, the Thinking Putty will suddenly stick to the side that was repelling it! The electrons in the putty have realigned themselves so that they can be attracted to the side of the magnet that is facing them.
- Sinking Magnets - Test a magnet and a non-magnetic object of comparable weight, and see which one sinks the fastest into the Thinking Putty. The putty has so strong an attraction to the magnet that it can actually pull it down farther.
