The team at SD State University dropped baby carrots and "sippy cups" onto various surfaces (including countertops, highchair trays, tile floors and carpet), picked them up within five seconds, and tested them for germs--which they found plenty of.

"We wanted to know if there was any truth to the theory that bacteria need time to attach to surfaces of fallen food or commonly dropped items like sippy cups," said co-author Scott Kelley, associate professor of biology at San Diego State University, in a press release. "Unfortunately, for those of us who lived by that rule, it looks like a total myth. Five seconds is all it takes."
