TheBackyardScientist | Ping Pong ball filled with liquid nitrogen? Insane Speed! @TheBackyardScientist | Uploaded September 2015 | Updated October 2024, 1 week ago.
Join the science discord! discord.gg/pw5sZ3PTye I was on Reddit yesterday, and I saw a cool GIF on r/woahdude. It looked so cool I had to do it. Also people were debating on how fast the ball was really spinning, and I had to find out for myself so I grabbed my camera that can shoot up to 1000fps. The original poster estimated the speed at 10,000 rpm, but the ball was really spinning 30,000 rpm in my experiments!
