A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
A more stable polymorph of water than common ice (Ice I h), which instead of melting when above 0°C (32°F), only melts at 45.8°C (114.4°F). When ice-nine comes in contact with liquid water below 45.8°C, it acts as a seed crystal , and causes the solidification of the entire body of water, which quickly crystallizes as more ice-nine.
Ice from a theorized superionic water may possess two crystalline structures. At pressures in excess of 50 GPa (7,300,000 psi) such superionic ice would take on a body-centered cubic structure. However, at pressures in excess of 100 GPa (15,000,000 psi) the structure may shift to a more stable face-centered cubic lattice.
It can mix metal shards with your ice. David J. Neal. October 16, 2023 at 5:12 AM. About 8,800 countertop ice makers have been recalled because nobody wants broken pieces of metal in their ice.

The shooting happened around 3 p.m. on Christmas Eve. The child, 4-year-old Jah’el E. Walker, was later pronounced dead.
Ice crystals create optical phenomena like diamond dust and halos in the sky due to light reflecting off of the crystals in a process called scattering. [1] [2] [15] Cirrus clouds and ice fog are made of ice crystals. [1] [16] Cirrus clouds are often the sign of an approaching warm front, where warm and moist air rises and freezes into ice ...
There were 30 such accidents recorded in 2023, the most recent year for which full-year accident data are available, amounting to a risk of one accident every 1.26 million flights, says IATA.
