Time-out bottles. Fill a bottle with 3/4 water, one bottle of glitter glue, & ultra fine glitter. Then send this bottle with your child to timeout and they can watch it settle to calm them. Once the glitter is settled their time is up! i was looking for this pin, thanks for pinning!
Printmaking with Bubble Wrap from @Modern Parents Messy Kids. Cheap and easy and fun. For the older group, they can also make extras for the younger guys. Great demo for pre made paper for younger group, who can use it for background paper for a project.
