Stainless Steel Ice Pack

Made from stainless steel rather than plastic, this ice pack not only saves water but it saves users from having to store it in plastic, too. It stays cold for four to six hours and reaches its lowest temperature after two hours in the freezer. It’s non-toxic and filled with distilled water—so there’s no chance of it leaking any unwanted substances.

Superionic Ice, or Water Simultaneously Solid and Liquid, Exists

A theoretical discovery dating back to 1935 by Percy W Bridgman, superionic ice—a state of water that’s both liquid and solid under extremely high pressure and temperatures—couldn’t be proven by scientists. That is, until now. Through a process involving diamond anvils and intense bursts of laser, a super-dense form of ice transforms into superionic ice. Here H2O severs, causing crystalline oxygen to harden with hydrogen …

The Lightest Form Of Water Yet Discovered: Gel-like Ice

It may come as a surprise to most that there’s not just one type of ice. In fact, there are 17—varying substantially in structure and weight—and an 18th “in development.” Only two types appear naturally on Earth, the common hexagonal version and upper-atmosphere cubic ice, but scientists have been able to produce “a type of porous, lightweight ‘aeroice’” according to New Scientist. Pressure causes variations …
