Calming Jar :: Time Out idea. Fill w/ hot water, add 1 tbs glitter glue, 3 tsp fine glitter, & a drop of blue food coloring. Have the child shake the jar & watch the glitter fall. When all the glitter has settled (and when the child has calmed down)
Considering having the teens make a giant batch of blue glitter slime in our water table and then letting them take some home in baby food jars. Might have them put the plastic sea creatures in the slime too, instead of making the shark jars.
