you’re right. But I could be sipping on heavy water, or
deuterium oxide, aka D-2-O, just as easily. Well, not just as easily… it’s super expensive,
and you have to, like, buy it from lab supply stores, but you get my point. Deuterium is a form of hydrogen, or isotope,
with a bonus neutron, which makes it twice as heavy as the regular hydrogen we all know
