What do ping pong balls have to do with nuclear energy? A lot more than you'd think. In this brilliant physics experiment, one falling ball kicks off a chain reaction, triggering dozens more in seconds — a powerful visual of how nuclear fission works at the atomic level. This is the science behind atomic bombs, nuclear reactors, and how energy multiplies exponentially. Simple. Satisfying. Mind-blowing. ➡️ Follow @civilext_ for more incredible science and engineering demos! #ScienceExplained #Cha
