The metal that pulses like a beating heart
HERE’S THE INTERESTING PART
Drop a blob of gallium into sulfuric acid with a rusty nail, and it doesn't just sit there—it violently throbs like Edgar Allan Poe's tell-tale heart. The acid strips the metal's oxide layer, dropping its surface tension so it flattens out, touches the iron nail, regains its tension, and balls back up, repeating until the chemical fuel runs dry.
One discovery leads to another.
