Crazy Aarons Thinking Putty 3.2oz - Super Magnetic Strange Attractor (Toy)

I bought this because I am a hard-core science geek and I have a lot of very powerful magnets to play with. The product works exactly as described except for the long-span reaction, which is supposed to be a fluid-type reaction where it smoothes out and looks like a little droplet. It never really smoothes out, even after a week the quarter-sized glob I was testing held ridges and my fingerprint, although it did spread out pretty well. (That whole issue may be due to the added magnetic properties, which can reduce the liquid reaction state.)I just want to warn everyone who is thinking about this product for a small child: it s very cool, great way to learn about magnetism and hexotropic substances (latter for older students, obviously) the way that it is made magnetic is by suspending ferrous particles in the putty. These stay in the putty fairly well. (no detectible magnetic reaction reduction after 3 weeks of 3-4 hours/day being magnetized and demagnetized repeatedly)...Read more

This review is in two parts, first Thinking Putty, second the individual color review.Thinking Putty - This is basically silly putty. Same feel, texture, material (silicone, which doesn't dry out), etc. What is different though is that you get a lot more then those small and even big egg shells. You get 1/5 a pound, or 3.2 ounces. Basically the tin covers your entire palm area easily. Although the tin is half full so it isn't too hard to put it back in.The other difference is that these come in much better colors, well unless you like the coral pink of silly putty. These colors make Thinking putty special. You can get all the primary colors, red, white, black, blue, green, etc. OK, those aren't hard to imagine. Then there are metallic and electrics. These I believe have mica in them. They are shiny and have swirls slightly darker and lighter colors. I say slightly. Think of a pearl or dull metal. Then there are the color changers. The use heat to...Read more
