How A Black Box Works 🤔

Wire a circuit board to record voices.Then add memory chips that can store a couple hours of conversations and sounds.Lock that memory inside a tiny metal safe before connecting it to the power source.Then attach an underwater beacon that will start pinging if it sinks in the ocean.Seal everything inside a thick metal case and paint it bright orange so it can be easily seen if it's lost.

Now you've built a small device that can out outlast a plane crash.It can capture what the pilots said in their final moments, so we can determine what caused the tragedy.
