Observers Disturb What They Measure | Understanding the Quantum World
What if you could exist in two places at once and give a random answer as to which of the two locations you are? Particles can, and "both" isn't an acceptable answer, making quantum mechanics a difficult field of study. Prepare to take "please only check one" to a whole new level.
