Some college students will do anything for extra cash, even if it means sniffing livestock excrement.
Students at Purdue University in Indiana can earn $30 per
session to inhale and then rate whiffs of air collected from barns
filled with hogs, cows and chickens.
It's a science experiment conducted by a professor of
agricultural and biological engineering. He's searching for ways to
improve methods for estimating a given livestock farm's odor
The students' sniffing will help with his research to determine
how far odors can travel and how far residences can be to a
livestock farm and not be affected by its smells.
