The Nose Knows
MYTH: IS IT POSSIBLE TO TRICK A BLOODHOUND'S SENSE OF SMELL?
Explanation: MythBusters Jamie Hyneman and Adam Savage sniffed out whether throwing a bloodhound off a scent is as easy as it's portrayed in movies. According to Hollywood, all it takes is some simple zig-zagging around or dashing through a river to confuse a pooch.
But when Jamie Hyneman tried to escape a bloodhound hot on his trail, it proved nearly impossible to ditch the dog.
A bloodhound's olfactory sense is said to be about 1,000 times better than a human's, which is why the canine is so good at sniffing out our odor-emitting skin cells. In fact, that personal perfume is strong enough that none of Jamie's bloodhound-busting tactics worked. He zigzagged and doubled back on his trail, ran through a river, washed and changed clothes, doused himself in coffee and cologne, and even covered his tracks in ground pepper — all to no avail. Each time, the bloodhound sniffed right through the ruse and found the hiding Hyneman.
Up against centuries of top-notch breeding, the busted myth was no match for the bloodhound's superior schnoz.
