The Mind Jar is a meditation tool to use when you are stressed. When you shake the jar the glitter (your thoughts) are all over the place. Watch them slowly settle while you calm down. From blog, "Here We Are Together".
Calming Jar for Kids: when a child is overwhelmed, shake it up and have the child sit and watch it until all the glitter settles back to the bottom. The jar is a great time-out alternative when kids are simply overexcited, upset, or overstimulated rather than in need of correction (and would be great for teachers as well). Fill jar with 1T clear glue per cup of hot water, 1 inch glitter, and food coloring.
Time out/calm down bottles- original source. If child is too excited or angry or agitated, give them their bottle. They shake it up really well & sit somewhere quiet. Once the glitter is all settled (~5 mins) their time is up. If they try to mess with the bottle, it will only make their time out longer.
