"So exactly how much force is the ice capable of exerting? Well, people have been trying to work this out for a long time. In 1784 and 1785, one Major Edward Williams took advantage of the weather in Quebec and repeatedly tried and failed to find a method of containing ice. Williams at first tried to seal water inside of artillery shells, the cast iron plugs of which were launched 475 feet at an astonishing 20 feet per second when the pressure become too great. Unperturbed, Williams then took to anchoring the plugs in place using hooks, only for the shells to split in two. In another experiment, an attempt was made to fill cannons made of one inch thick cast iron with water only for them too to split when it was frozen. Academics in Florence later tried to fill a ball made of one inch thick brass with water only for that too to crack when it was frozen. They later worked out that the force required to do so clocked in at around 27,720 pounds."

I remember the first time I was introduced do the idea of differing forms of ice was in Vonnegut's Cat's Cradle. While the ice-nine from that book was fictional, it was still a fascinating idea: Depending on temperature, pressure, and make-up; ice would form different crystal structures with unique properties.

ice is stupid. people standing on ice are more stupid

Whenever I think of posting science links, I think, "Would Wraith/ Smath74/mrfrog/0EPII1 think this was cool?

Ooh, I get a mention

Yes this is cool, I always wondered about it myself, but was too lazy to google it.

What if I use a brass/steel sphere with 6 inch walls, and an in internal diameter of just 6 inches. Would that be enough to crack it open? If yes, I would love to do repeated experiments to find the ratio of wall thickness to internal diameter that would stop the ice from cracking open the sphere.

Admittedly I didn't have time to read the article when I originally posted Mr. Cool Ice but yeah that actually is extremely interesting. I bet there are tons of planets out there that have extremely high atmospheric pressures to the point where all these crazy forms of ice occur naturally.
