Can you make butter in a jar?
- heavy cream
- a jar with a lid
- Check with a grown-up before you begin.
- Nicholas of Michigan sent us directions for how to turn cream into two parts, a solid, butter, and a liquid, buttermilk.
- All you do is put some heavy cream into a jar with a lid.
- Screw the lid on tight and begin to shake it.
- The cream has little globs of fat and protein. When you shake the jar, you get the fat and the protein that are moving around in the cream to stick together.
- Keep shaking the cream back and forth until it thickens. In about 10 minutes, it will turn to butter.
- When you shake the jar, the little fat and protein globs in the cream hit each other and stick together, forming a larger and larger glob.
- The glob is butter! The liquid that's leftover is buttermilk.
So, you know that cream can be separated into two parts, but can you put them back together? Experiment with this and send your discoveries to ZOOM!

well, I used other ingredients. I just use a clean glass bottle, 200 grams of heavy whipped cream and a little salt. I shaked the cream and a little bit of salt in the bottle for quite some time and it got thicker... it then seperate into two components-a clearer liquid and a yellowish solid. I pour off the buttermilk and tada! I got butter!!!

Instead of using a jar we used the ice cream ball that you can kick around. We just added the cream to the ball and we rolled it around for about 15 minutes... and it worked!

I tried it and it was some goooooood butter!!! I really didn't think i'd work until I tried it. My mom was amazed to see that I could make milk into butter. Now my mom says that she won't buy the buttermilk Smart Balance anymore but she'll only eat this one. So, I have to make butter everyday now!

well when our class made the butter we all liked it very much because we all got to shake it and make our own and then we were done we got to put the butter on the cracker. I found out when u shake the jar of cream it makes it more thick and it goes faster
