The discussion centers around a video showcasing a fidget spinner, which the poster believes demonstrates the Magnus Effect. Initially, the video was private, but it later became accessible for viewing. Observers noted that while the Magnus Effect typically causes sideways motion, it was not prominently visible in this clip. Some participants pointed out that the timing of the spinner's center release may have affected its motion. Overall, the video serves as an interesting example for those curious about the Magnus Effect in action.

Hello all, I came across a video I shot with my kids from when fidget spinners were popular (dating the clip). I thought it was an interesting shot likely showing the Magnus Effect that some of you may find interesting.

We spun the fidget up with compressed air to a fairly ridiculous RPM and let her drop, here is the clip:

The Magnus effect would make things move to the side, I don't see much of that. It looks like the center is released a bit later, that's why it is behind in the motion.
 
Thread 'General principle of turbomachinery: true also for rocket turbopumps?'
A rule of thumb of aircraft engineers is every 10% increase in the power level engines are run at corresponds to a 50% decrease in engine lifetime. This is a general phenomenon of turbomachinery. Then it is likely it also holds for rocket turbopumps. Then quite key is the rule also holds in reverse, every decrease in power level by 10% can result in doubling the lifetime of the engine. Then by running the engine at 0.9^5 = 0.60 power level can result in 2^5 = 32 times longer lifetime. For...
