The five second rule
We've all claimed it, or at least been there and been repulsed by somebody else who's claimed it. You know, you drop a delicious Twix bar on the ground (why do Twix come in those fragile little packages? there are TWO bars in there, mind you, hence the name Twix) and quickly pick it up and eat it and cite the Five Second Rule. Like Finder's Keepers and Shotgun, this is one of those unstated but universally accepted truisms.
But how "true" is it, you may wonder? Well, according to this study, not only is it true, but you could actually extend it to a thirty second rule with no consequences.
OK, pick up that Twix and enjoy it, right? Not so fast, according to these guys. Of course, I don't think anybody in their right mind would pick up a piece of food that had just fallen in a Petri dish full of salmonella, so I'm not sure of the validity of this study.
I guess we'll just have to rely on our good old common sense. You gonna eat that Twix?
