Dating a blue mason jars
If you find that it is settling too fast, you can add more corn syrup/glycerine or more salt.(Note: if you do want to use salt, you might want to try pickling or Kosher salt as it will make a clearer solution than table salt.) We also decided to transfer our mixture into a recycled plastic jar for a couple of reasons.Have your child draw pictures and record any observations in a science journal.You could also have them make a graph of their results. It really didn't seem to make a difference whether we used corn syrup or glycerine (they both had about the same settling rate) and as corn syrup is much cheaper than glycerine, I would recommend using that.In one, we added the big, fat (cheaper) glitter and it, literally, settled in about 10 seconds flat. In the second container, we added Elmer's White Glue, which turned it into an opaque mess. So, a few days later, after looking at the different recipes and thinking about the science behind what makes them work we decided to make an experiment out of creating the glitter jars.(I'm talking about the science of the jars here, not the science of meditation - I'm definitely not qualified to talk about that because I haven't been at all successful with meditation. We kind of went overboard, but once we got on a roll we kept thinking of other ways to tweak the recipes and the girls were having fun, so we went with it.I've seen these jars all over Pinterest the last couple of months or so, sometimes called "mind jars" and sometimes called "calm-down jars", and thought they might be a fun craft to make with the girls.(Okay, okay, so I'm totally dating myself here, but they remind me of the plastic glitter wands from the 80s and I really wanted to make one for myself.) Basically, mind jars are a tool to help kids, or anyone, when they feel overwhelmed.
Then have your child place the jars in a line from the fastest to the slowest settling times.(If you do use more than one color, don't be surprised if they settle out at a slightly different rate.Later, we made a jar with silver and pink and the silver definitely was slower at settling out; I'm not sure if that is due to different size or density of the glitter.) Put the top on and let your child shake the jar.As far as I can tell, the post Meditating with Children on "Still Life with Circles", is the first post I can find about the jars.It refers to the book, Moody Cow Meditates that has a recipe for the jars in the back.
