Episode 442 - Just what is a metal anyway

August 2, 2021

Just what is a metal anyway? It can be hard to classify things, no matter what you do there's always exceptions to the rules. Chemists, Physicists and Astrophysicists have wildly differing opinions on what a metal is. Although there is disagreement about what makes a metal, can you find new exceptions? What needs to happen to turn water into a metal? Can pure water be made to conduct electricity without needing a Jupiter sized planet? How do you turn water into a golden, shimmering, conducting metal?
