Wind tunnel visual California Academy of Sciences San Francisco's Golden Gate Park 20170519-150946 C4

This is a photo I made of a six minute video explaining the early flying dinosaurs, Pterosaurs the was playing in the special exhibit of our California Academy of Sciences in San Francisco's Golden Gate Park. The writing on each of the two video screen shots are self explanatory. The interesting exhibit room was filled with information about these ancient bird and the principles of flight even for some creatures that were 16 feet - nearly 5 meters - tall. The wind tunnel screen caught my attention before I could capture the image. I after shooting the flying dinosaur screen I waited for the video to recycle to get the wind tunnel image. I shot this using my Canon Powershot SX50 at speed preferred setting.
