Product Description

Color: Krypton

Product Description

Thinking Putty comes in 30 colors, including glow-in-the-dark, heat-sensitive, and electric-colored putty. It can stretch like rubber and bounce like a ball, and because it's silicone-based, it won't dry out or crumble over time. It's part toy, part stress reliever, part physical therapy and entirely addictive. Once you start playing, it's hard to stop! Glow in the Dark Thinking Putty is hypnotic and irresistible. Milky white in daylight, their glow magically appears when the lights dim. It's translucent -- so the glow appears to come from deep within! Made in the USA. Krypton DEFINES eerie, outer-space, alien, radioactive green! Charge with sunlight. Wakeup before sunrise to see it glowing hours later!. Perfect for anywhere you like to play. After exposure to light (the brighter, the better) these colors will glow for hours.

From the Manufacturer

Krypton Thinking Putty DEFINES eerie, outer-space, alien, radioactive green. Charge with sunlight or our Backlight Keychain for fantastic brightness. Wakeup before sunrise to see it glowing hours later.

Color: Super Magnetic Strange Attractor Verified Purchase
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) HOWEVER... They can, and DO, come out. Even if you play with it for a few seconds, I recommend passing the included magnet over your fingers and hands and washing well because they HURT BAD when you get one in your eye. I learned this lesson the hard way and just wanted to let parents, teachers, nerds, geeks, and all the other people who might touch this stuff so that they can avoid it.

Color: Super Magnetic Strange Attractor Verified Purchase
Length: 2:56 Mins
I bought this item just as a fun toy to squeeze and play with.

However I was disappointed. The putty is not very magnetic and will really only work with really strong magnets. I was disappointed to find out that it will not pick up metal objects unless it is magnetized.
On the plus side it was very fun to squish and play with.
Overall, it was an okay product, probably too much money though.

This is my first video I've made for amazon. I had a sore throat, so I did not put up audio, just text. In my video I tried to mostly show the abilities of the product instead of my opinion of it. I would appreciate constructive feedback on how to make future videos better.

Color: Liquid Glass Verified Purchase
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 change color to a lighter version of the color. Cool to return to the original shade. And the glow in the darks. One color during daylight, another at night. And these do no use the glow material they used 10-20 years ago. This is more expensive but glows some 10X longer. And then there are two special colors. Magnetic, which is slightly or slowly if you prefer magnetic. And glass, which is clear.

For more on these, please see other reviews.

Is thinking color kids? No. Give them silly putty. It is cheaper. If they love that, then give them this. Also this is called thinking putty because it is for adults to mush around while they are thinking. Or think of it like a stress ball.

Color: Liquid Glass
I saw people had bad things to say about this putty and wanted to give my 2 cents. I have been loving this thinking putty since I bought some for my son. I think the magnetic one is the coolest one. We have a few of the color changing ones which I find a bit boring after a while. My 2nd favorite is the liquid glass one. It is quite a bit more softer droopier (dont want to say drippier because its not like slime)....it doesnt really hold a shape but you can squeeze it (feels very nice)...and the coolest thing is how it gets cloudy when you handle it but then within seconds that you stop touching it it starts to turn clear again and it does look like liquid glass. I like to just twist it and watch it go back to being clear. So this glass one you cant really mold into shapes or anything like that but with the magnetic you can a little bit before it deforms back into blob shape...the color changing ones are about a silly putty consistancy. These are fun. Yeah you can save money by going to the dollar store and getting boring plain pink silly putty but thats pretty boring. If you are thinking about buying this for a kid and dont know which one to start with definitely get the magnetic(provided you are not afraid of them swallowing magnets because it comes with a super strong magnet)...but if you just want to fool around with something cool for a few minutes every once in a while try this clear one.
