Both children and adults will love this rainbow galaxy sensory bottle. When it swirls it looks like a rainbow galaxy, and when it stops it looks like rainbow colored twinkling stars slowly falling in the night sky. Calm down bottles like this are most often used for no mess sensory play, to help calm an overwhelmed child, as a “time out” timer, or as a meditation technique for children. They are just as effective for adults. Space Discovery Bottle | Space Calm Down Jar | Space Sensory Bottle
