Particle Image Velocimetry (PIV) Explained - How do we see airflow in wind tunnels?

How do we tell what is going on in air, when we can't actually see it? How does PIV work in wind tunnels? Today, I explain PIV (Particle image velocimetry), a great way for determining the velocities and structures of airflows in wind tunnels.
