Flying playing cards are awesome

Video Description

Today I get to show off the results of my most recent high-speed filming obsession. I wanted to understand the airflow around a flying playing card - when you flick or throw a card across a room like a frisbee. Now in glorious 1500-7500ish fps video, we get wingtip effects, oscillatory vortex shedding, and gyroscopic effects. I hope you enjoy, cause I certainly had fun filming it!
