Kids' Activity-Making Butter

I have all of these things that I have wanted to do with my boys this summer and to be honest, I haven't seen them a whole lot! They play outside all day long and I just see them as they come in for lunch, drinks and snacks. I have loved it that they have been so active, but I wanted to hang out with them a little bit more! The other day they got all of their "stuff" done early and I hurried to throw in an activity before they left for the day. I saw this fun idea for making butter here, and had all of the stuff for it.
I turned on a movie as it takes about 20 minutes to make and gave each of the boys a jam jar filled 3/4 of the way full of heavy cream with a lid on it. They watched the movie (Harry Potter and the Prisoner of Azkaban, I have seen it A LOT lately. Palmer is obsessed with it) and shook their jars of cream. Every once in a while I took over the shaking for them, but for the most part the did it all. As you can see from this picture, Palmer was pretty intense with the "shaking" part. He did a great job!
McKay sat and laughed at the boys shaking the jars.
We stopped the shaking every so often to check our progress and I took a few pictures. It was fun for the boys to see the process.
Almost done!
A little longer...
Done! I poured off the liquid into another jar (buttermilk for our buttermilk pancakes, yum!), and then pour a little cold water working the butter around in it and then poured it in the sink and added water, working it around and pouring it off until the water ran clear.
The buttermilk.
I made some fresh homemade banana bread and we ate our yummy butter on it warm out of the oven. It was so much fun and really cool to watch the process.
Delicious!
