Thinking Putty - Goodnight Cactus - Multi-Color Sensory Putty for Kids and Grown ups in a 4" Tin - Creative and Endless Fun, Stress Relief Therapy Toys, Never Dries Out - Made in USA

The putty has a nice consistency and changes color with heat, although getting it back to the base color is kinda hard (although you can always put it in the fridge to change it back). This is probably one of the best versions of Crazy Aaron's putty.

This putty is genuinely satisfying to use — I picked it up as a stress reliever and it delivers. The color-changing element makes it extra fun to play with; watching it shift as it warms up in your hands is oddly mesmerizing. Great quality, doesn’t dry out or get sticky, and it’s one of those things you just can’t put down. Crazy Aaron’s never misses.

Personally I've been quite a fan of these thinking putties and discolor changing option was one of the better ones that I've purchased. It accurately changes colors given heat in stretching and returns to the deep purple after cooling down. It just makes me want more of these products on Amazon

I've never used a putty before, aside from Silly Putty when I was a kid and remember really enjoying it. The Crazy Aaron's "Goodnight Cactus" putty is so fun. I just got it today and I've been thoroughly enjoying it the past 30 min. The color changes quickly, but I cannot seem to get it to the yellow color. Unsure how hot it needs to be to turn yellow. Maybe I'll play with it over my fireplace to find out. The container, as many have said with this brand, is very difficult to open. I had to use the tip of a steak knife to gently pry it open. Took about 5 minutes of consistent prying to get it open. I bought 2 other versions of Crazy Aaron's putty so I am going to let them sit right side up for a day to see if the putty settling off the top and into the base will help the opening process. You can see 3 different clusters in one of the photos, the purple is untouched, the larger pink was me kneading it for about 10min (I have colder hands than most people and live in MN where it's 10°F right now, so it'll probably take less time for others). And the third, smallest cluster is one I've been aggressively kneading, pulling, stretching, rolling, and blowing with hot hair for 20 minutes to see if I can get it to turn yellow. As with anything tacky that's for play (to prolong the life of the putty) I recommend washing your hands or using hand sanitizer first so you don't add dust or oils to the putty, and don't let it get into your hair or fabrics (i.e. couch, carpet, bedding, etc). The consistency is good, not too tacky or sticky, and does not seem to be the type of putty that would dry out with use or dry out quickly. Overall, this is a great fidget tool and I'll probably order some for my practice! 4 stars instead of 5 due to the opening difficulties and the color not being able to change to yellow with normal/heavy use.

My favorite putty for the classroom! It is not sticky and does not leave a film or greasy feel on your hands. Perfect for therapy for all ages.

Good stress reliever and helps strengthen my fingers and hands.

I just love this stuff. I am a senior citizen and this gives my hands something to do as I watch TV. Great quality. I wish the tin would open easier, but that's a minor issue.

I love this putty so much it changes colour so fast (pink to yellow) and becomes purple if you put it in the fridge. It’s a bit hard when it’s brand new but once you start playing with it a bit it becomes perfect. Definitely recommended!

this putty is so nice and fun to play with, the 3 colors that it switches through are so pretty.

Solo cambia entre el color morado y el rosa. Nunca se vuelve amarilla como aparece en la publicidad.

Love it, great

Arrived on time and as described

Good quality, but couldn’t make it to yellow:-)
