Fill a jar with water, add glitter glue or glitter and glue. Shake and watch the glitter swirl and settle.
Watching the cloud of glitter spiral around can be a little like our feelings sometimes they all get a little too much and everything seems cloudy. But if we stop, take notice and breathe, everything will settle down soon. Use your worry jar when your feelings are getting too much and focus on the glitter and your breathing.
