Any questions about this video?

As part of preparing for our impending move from Indy to Grand Rapids, my family and I have made a couple of visits to the area. These by necessity combine business with pleasure, since our three kids (ages 2, 5, and 7) don’t handle extended amounts of business well. On the last visit, we spent some time at the Grand Rapids Childrens Museum, the second floor of which is full of stuff that could occupy children — and mathematicians — for hours. This “exhibit” was, for me, one of the most evocative. Have a look:

I asked this on Twitter a few days ago, but I’ll repost it here: In the spirit of Dan Meyer’s Any Questions? meme, what questions come to mind as you watch this? Particularly math, physics, etc. questions.

One other thing — just after I wrapped up the video on this, someone put one of the little discs rolling on the turntable and it did about a dozen graceful, perfect three-point hypocycloids before falling off the table.

  1. Thanks for the heads up. I’ve never been to this museum. Maybe I can get my parents to take my son there while we’re visiting in August. (I’ll be at a technology workshop in Muskegon.)

    Your kids might be too young, but my son loves Craig’s Cruisers.

  2. Just one suggestion: don’t call it “Spinning Table.” Reduces the range of questions.

  3. (The video isn’t working now.)
