Here’s an idea from one of our Minnesota Hands-on Science Ambassadors, Lisa Schoneman, using Pearl Swirl Solution:

I use pearl swirl to make behavior bottles. I shake the bottle up and put it on the table near the “Take a Break” chair (time out). I tell them they need to sit there until the bottle has stopped moving and then they can either come back to the group and join us, if they are or they can shake the bottle one more time. When they are done with the bottle they are ready to join us back in the group.
