The Science Behind Dogs' Incredible Sense Of Smell

In this lab, they use different flow visualization techniques to help detect contraband, residues, and develop trace particle detection methods. Part of this video was sponsored by Caseta by Lutron. Find out more at https://casetawireless.com/veritasium
