One of the projects my BIL had to do for his math was make ice cream. What, you might ask? You heard right, he was doing a lesson on measurements and temperatures and calculating differences. I thought it would be cool to have wingnut have a go at it as well. The only downside to making it like this is it does not get cold enough to stay solid for long

Wingnut still loves his knobbed cylinders and I am going to find a way to make it more challenging.

While wingnut was working on his cylinders, BIL was reading up on his US history.
