The 5-Second Rule

Do you remember the “5-second rule”? Any food item dropped on the floor is “safe” to eat as long as it doesn’t remain on the floor for longer than five seconds before being picked up.

But is this actually a good rule to live by? A high school senior recently carried out a scientific study to find out whether or not the “5-second rule” was a good measure of food safety. The work was done during a seven-week internship at the University of Illinois at Urbana-Champaign (check out the UIUC press release here).

What a great example of making science fun and accessible to everyone!
