ten-second rule

Dropped snack grace

The ten-second rule is an informal guideline that food dropped on the floor remains safe to eat if retrieved within ten seconds.

The actual time varies by telling—some say five seconds, some three.

The rule has no scientific basis; contamination begins on contact.

I dropped my chip but invoked the ten-second rule.
