This is an important advancement in mermaid science.
There's a new compound that will let us breathe under water and in space! Well, really we already had a chemical compound that lets us breathe in those places. That would be O2, diatomic oxygen or oxygen gas, which we shove into pressurized canisters and lug into space or anywhere else that we need breathable air. But now, scientists have found another chemical compound that filters, stores, and releases high volumes of oxygen and is much less dangerous than potentially explosive tanks—probably.
