Jennifer Day, a biologist at the University of Washington in Seattle, set out to build a machine that could stuck massive volumes of air out of shipping containers and run it through a filter that a dog could sniff.
The reason?

A sniffing machine makes it quicker and safer for the dog while subjecting them to less stress. Read the story at Popular Science.
