 So if you drop some food coloring, if you don't use the paint, then all you're doing is gluing that bottle lid on or taping it on, and then you get to shake it. And then as the shimmers fade down from your glitter or your buttons fade down, that's your sense of calming that you get to experience. When all of those sink to the bottom is when you get to do your next activity maybe, or maybe it's a time that you can get up and go play. But it's a great activity for young children to do during the summertime.
