A ridiculous thing

I'm facing a technology problem of sorts this morning.

I'm trying to find something round to use in a demonstration for class. Sounds simple, doesn't it? Apparently, this is also covered by some sort of technology effect.

For starters I don't have any of the playground balls around the house, or a basketball for that matter. (Yes, I grew up in Indiana. I never really caught the basketball bug.)

However, I discovered that the jars and cans in my cabinet were not uniformly round. They rolled funny. A container of caulk that I found was a nice tube (with the pointy tip) but the caulk itself was not uniform inside the container. I know this because it rolled like it was drunk.

So, I think I needed to decide on a roll of blue painter's masking tape. What a silly thing. Today might not be the day to work on a server.

Either way, I hope the lesson works. Today is "Newton's first law" and "Newton's second law." Good stuff, really.
