Glow in the Dark Putty
Thinking putty is a great way for children to regulate and manage anxiety in a non disruptive manner. Due to the number of muscles in the hands, fidgeting can be a very efficient way of of regulating the entire body, leading to better focus, calming, attention and active listening.
This is a polymer putty(non-organic), which means that, unlike home-made slime, it will not create a mess on your carpets and couches. It can be removed quite easily and last longer as well.
