Water in frozen form is not only below 0 °C or 32 °F or 272 K, as we as postdocs all know, but also slippery and very solid as we experienced! A group of postdocs went out & experienced the feeling of graciously sliding over this frozen substance on thin iron blades – and we had a blast! Missed the fun? You can still go to the Oakland Ice Center to get in shape for the next time and amaze all of us with your newfound skills.
