One of these 6,420 dots is not like the others. Find it, then tell us how long it took.
That red dot is deuterium, hydrogen's heavy isotope. It carries a neutron that ordinary hydrogen doesn't have, which makes it twice as heavy. In Earth's water, about 1 in every 6,420 hydrogen atoms is deuterium, and the grid in this video is drawn to that exact ratio.
It's in every glass, every ocean and every raindrop. Freeze pure heavy water and the ice sinks instead of floating. That's how much one extra neutron changes.
Your filter can't take it out. Deuterium isn't a contaminant floating in your water. It's part of the water molecule itself, bonded in as HDO, so carbon filters, mesh and reverse osmosis let it straight through. Removing it takes specialized isotope separation.
Researchers propose that this heavier hydrogen jams the ATP synthase motor inside your mitochondria, the machine that makes most of your energy. It's a model still being studied, and it's why scientists look at deuterium depletion.
Litewater is up to 97% deuterium depleted. Now you know where to look.
