This one is about glitter jars! We made a couple of them using these wonderful instructions: http://recycledawblog.blogspot.com/2012/09/how-to-make-calming-jar.html
For this one, I used blue food coloring with silver glitter:
then I made a more durable plastic one with purple coloring and gold glitter. I didn't take pictures of it, but I did learn a valuable lesson-- mix the hot water with everything in a glass jar, let it cool a bit, and THEN pour it into your plastic container. Else your plastic container can melt and end up looking like Quasimo-tainer.
Lots of fun and my daughter loves it :) It'll be fabulous for when she's a bit older and needs to have a few quiet moments to calm down after a tantrum before we talk things out.
