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!
plastic bottle + vegetable oil (half fill the bottle) + water (fill the rest of the bottle + 10 drops food coloring + alka-seltzer (broken into pieces, placed 1 at a time into the bottle) = lava bottle
