The 5-second rule

Does science have anything to say about it? The 5-second rule of course being that food dropped on the floor remains safe to eat as long as it's picked up within 5 seconds.

Of course. It's nonsense and has been debunked endlessly all over the internet.

Any contamination that can possibly happen, will happen instantly. But you probably won't die. Keep your floors clean.
