Videos of “Lift, Boundary layer separation, and curve balls”

Here are the videos from the “Lift, Boundary layer separation, and curve balls” demonstration. The GIF titles link to the full videos.





This one is a little hard to follow. The balls are orange and appear near the top left corner. The ball only rises a little bit and the camera angle makes it hard to see. If you watch carefully you see that the flight appears a lot flatter than a pure projectile motion (because of the perspective the ball appears to float in mid-air at one point)would lead to, indicating that there is a vertical lift force. This is better watched on the full video.
