A refreshing glass of cold water. If you think I'm talking about H2O , then you're right. But our thinking is if we could be sipping on heavy water or Deuterium Oxide (D2O) then what happened? First of all, it's super expensive, and we have to buy it from the lab. Deuterium is a form of hydrogen or isotope, with an extra neutron, which makes it twice as heavy as regular hydrogen. That's why when there's Deuterium in water molecules. it's about 10% heavier and we call it " Heavy Water ". In small amounts, heavy water is fine. In fact, in combination with an oxygen isotope, it's used in lots of nutrition experiments in humans because it's a useful way to track how much energy we're spending. But, too much will almost kill us. If we push Deuterium oxide in rats, they will die. In fact, plants will stop growing. The toxicity is related to what's called the KINETIC ISOTOPE effect. In the incident of heavy water...
