  1. Whoa! Thanks for the link, but at least spell my name right! And had you already seen Beer Geometry? Not that big a deal? I’ll just have to search harder.

  2. Whoops. First day of school. I’m somewhere else right now.

    I showed my kids beer geometry during show and tell one day last year which totally, collectively freaking blew our minds.
