How it works
Heavy cream has a lot of fat in it, By shaking the cream, the fat molecules begin to separate from the liquid.
The more the cream is shaken, the more these fat molecules clump together, forming a solid which is the butter.
The leftover liquid, after the solid butter has formed, is called buttermilk.
