Color Changing Frudge Putty Heat Sensitive - 4 Pack Frudge Putty - Ideal for Sensory and Tactile Stimulation, Event Prizes, Easter Bag Stuffer, Slime Party, Educational Game, Fidget Toy

But I cheated and used a blow dryer (in the tin and for a short amount of time) to activate the color changing! It really does take a lot of doing to make it start changing colors if you're doing it by hand, but it works (and changes more quickly afterwards), and if you're using it as intended, worth it. The purple and red very noticeably change colors, but the green is a lot more subtle! As you're working on the green, it goes from the darker slime green to an almost neon green and doesn't show the temperature change as much when it reaches the neon green color. Aside from that, the texture of it is kind of off putting at first. It has an almost oily feel to it, but as you handle it, it kinda sorta goes away? I can only assume you're either kneading it back into the putty, or you're kneading it into your own hands. Or a little bit of both. Either way, I'd probably avoid getting it onto clothes or furniture. It also kind of have a sweetish chemical smell to it. It's not a strong scent; you'd have to hold it to your nose to really smell it, but it's there. In case you are sensitive to that sort of thing. It's all in all not a bad buy at all. I was kind of hesitant because of some of the reviews (because I scan the reviews like nobody's business), but my personal experience was not bad at all. It definitely helps if you fidget with things with your hands, and it has definitely worked out the muscles in my hands, wrists and forearms!

I love the feel of this putty! It's the perfect consistency - a little bit hard at first but as you use it it softens up. Two of them don't change colors when I use them at room temp (the red/yellow and purple/pink), but I put them in the fridge for 15 minutes and they got to the "cold" color. This adds an extra sensory input (cold to warm) which is great! The metal tins don't feel airtight, so I put them in other resealable containers.

Definitely takes a while to turn color , you really have to work with it a while.

It was given as a gift for a 3 year old. She is having the best time with it.

Missed the opportunity to send this back but would have. Bought as Easter stuffer so didn't open until a month+ after purchase. We've had many different putties and compared to those, this putty is hard. Too hard for small hands to manipulate. It color changes and is stretchy but too hard to play with otherwise. *I contacted the company and they were very helpful and accommodating.

These are super cool! The colors took a long time to change, but we worked on each one, and the change is very clear and obvious when it happens. It was much easier to warm the whole thing up and then use cold things to change a part back than it was to change it to the warm color. There was a lot of putty in each tin. Lots of fun!

Unfortunately, this product does not change colors with the head of your had as advertised. It might be fun to stretch and roll it around, but the lack of color change is disappointing.

Great texture, no stick or slimy feel, no film or smell left on hands. Kids love it!!
