The most official water costs $120k a gallon
TL;DR · WeSearch summary

The most official water costs $120,000 a gallon We all learned in science class that water freezes at 0 °C or 32 °F at atmospheric pressure. Even after you distill out all the dissolved salts and minerals to get pure H2O, not all H2O is created equal – and for the most precise temperature measurements, the differences really matter. Here’s the problem: hydrogen and oxygen atoms aren’t all identical.

Opening excerpt (first ~120 words) tap to expand

The most official water costs $120,000 a gallon We all learned in science class that water freezes at 0 °C or 32 °F at atmospheric pressure. But what water, exactly? Even after you distill out all the dissolved salts and minerals to get pure H2O, not all H2O is created equal – and for the most precise temperature measurements, the differences really matter. Here’s the problem: hydrogen and oxygen atoms aren’t all identical. All atoms of a single element have the same number of protons by definition, but they can have different numbers of neutrons, forming different isotopes. We need to know how much of each isotope to use for our experiments. Credit: OpenStax First, let’s go over the isotopes of hydrogen and oxygen.
