Watch a single bubble of water form, atom by atom 🫧 For the first time ever, scientists captured the process of two atoms of hydrogen and one of oxygen combining to form water – observed directly at the molecular scale. Using a tiny piece of palladium as a catalyst, researchers watched hydrogen atoms embed into the metal’s lattice structure. When oxygen was introduced, the hydrogen re-emerged and bonded with the oxygen atoms, forming a bubble of water – the smallest ever seen – recorded in real
