Crazy Aaron'sThinking 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

First, this is SO fun.I love the color changes. This does not leave a residue and starts off fairly firm but not hard. It soften ups as it is worked and warms up. It is a great therapeutic exercise for my arthritis.

I love that this one changes colors when it warms up or cools down! So much fun for my daughter!

The best! I am obsessed with aarons thinking putty. The color shift in this one is fun.Reminds me of Arizona 🌞🧡💓

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 students love this putty. It's not slimy and keeps it consistency. I really like it.

This putty is fun to play with. It changes colors when it gets warmed by hands or cools off in the room. Make a couple pieces and warm one in your hand and cool the other piece off then twist them together. Nice big tin storage container with enough putty for 2.

worked great, affordable, matched description, and delivered on time. would recommend

Ordered for my daughter for present. She is so disappointed right now because the product leaked , and we can’t open the container. It’s stuck. Can’t manage to open to even see if the product inside is ok. We cleaned some off the side trying to get it open but there’s more stuck in lid.
