After seeing glitter jars all over Pinterest for the past few weeks, I decided to make one of our own. (Most of the jars are called "time-out jars" or "calm down jars") I knew I didn't want ours to be a time-out jar because I didn't want any punitive connotations, so when O requested blue food coloring and blue glitter, I decided that we'd call it our "Starry Night Jar" (since we love Van Gogh's Starry Night painting).
To make the jar, we filled it with warm water. We added blue glitter and blue glitter glue. The glue creates a swirling effect when you shake the jar, and I added a little extra clear glue (school glue, but it's clear,not white) to make it swirl a little longer. I didn't measure anything...just eyeballed it.
Once when E(2) was extremely tired and fussy, I sat with her on the kitchen floor and grabbed the jar and shook it. We both stared at it and talked about how the glitter (stars) was slowly drifting to the bottom. I was happily amazed when she immediately calmed down and stared at the jar for a minute or so. I'm planning to put together a peace basket, and this will be an important component of it.
