The experiment of Schrodinger’s Cat is where a cat is placed in a box with a minuscule amount of radioactive substance. When that substance decays, it triggers a Geiger counter which releases a poison that will kill the cat. However, whether the substance decays or not is up to quantum mechanics and chance.

Edwin Schrodinger did this experiment to ridicule those who thought quantum particles only collapse to a single state (dead or alive) if seen by a conscious observer. Quantum theory states that quantum systems can be in a multitude of states or conditions at the same time before being measured.

Unfortunately, many people back then and even now take this as a real example to prove their notions when Schrodinger made it for a very different reason.
