Sneeze Travels 100 mph
Explanation: Armchair medical science maintains that the involuntary respiratory convulsion known as a sneeze launches mucus from the body at 100 miles per hour, landing it 30 feet from the source. In pursuit of the right diagnosis, MythBusters Jamie Hyneman and Adam Savage cranked up their ultra-high-speed camera to witness the phlegmatic physics of sneezing in action.
The duo each sniffed some snuff to muster up strong sneezes, but even those gargantuan gesundheits clocked in at less than 100 mph. Make that way less than 100 mph. Adam's achoo erupted at 35 mph, and Jamie barely beat him at 39 mph.
As for whether a sneeze can go the distance, neither MythBuster could break the 20-foot mark. Instead, Adam's and Jamie's flying phlegm landed 17 and 13 feet away, respectively.
So while sneezes still spew snot fast and far, the busted myth proves their much-advertised speed and distance stats are full of hot air.
