My daughter and I had an absolutely wonderful trip visiting my best friend from college and her family in Colorado. My best friend always finds the most wonderful toys. This trip was no exception. She introduced us to “Crazy Aaron’s Thinking Putty”. My daughter absolutely loved it. Needless to say we left Colorado with several tins. It is sold in large and small tins. Amazon even has a small tin sampler. I watched as our two girls, ages ten and eleven played non stop with their thinking putty and never seemed to tire of it. It comes in many different varieties. Some of her favorites were oil slick, tidal wave (which is magnetic), scarab (which reminds me of an oily sticker), and amethyst blush (which is heat sensitive). Besides being really fun to play with I love that kids use those hand muscles to manipulate the putty which is great for this time of year when we are not writing quite as much as during the school year and need to keep those hand muscles in shape.
