Like who hasn’t picked up a piece that has dropped on the floor and ate after yelling 3 second rule, I know I have, a number of times.
That is actually a legit thing. So five food items were tested by Manchester Metropolitan University, to see if the rule is true, they dropped, bread with jam, cooked pasta, ham, a plane biscuit and dried fruit. And for three, five and ten second intervals.
Turns out that three second rule was the one that seemed the safest, expect for foods with high sodium, they can last for up to 5 seconds.
It’s actually a pretty cool study, you can check out more!
