Ping Pong ball filled with liquid nitrogen? Insane Speed!

The video tutorial demonstrates an experiment where a ping pong ball is spun using liquid propane. Initially, the baseline spin rate is measured by hand using a high-speed camera. Then, a hole is poked into the ball, and propane is used to spin it much faster. The results show a significant increase in spin rate, reaching up to 30,000 RPM. The video concludes with a summary of the findings and a closing message.

What was the frame rate of the high-speed camera used in the experiment?

• 1200 frames per second

• 720 frames per second
