Fastest 12,000 RPM Lego Vacuum Engine | World record!!! 

I hope you enjoyed the video!
It was quite hard pushing it to its limit, but it was worth it!
*At 5:08 I meant "break" and at 5:45 "vibrates"... I really don't know how this happened 🥲
A tyre of a car going at 50 kmh or 30 mph spins like 26 times slower than this engine...
The first version: • Testing a 8,100 rpm Le...
The way I measured all the results is quite useful but not totally accurate... So it can sometimes deviate by a few rotations...
If you didn't really understood how I calculated the speed:
It's quite simple...
I know that when the orange thing does one rotation, the propeller has completed 576. Then I stop the time measuring how long it takes the orange thing to do one rotation (the propeller 576). Then I divide 576 by the measured time, so I know how many rotations it does in one second. Finally I multiply it by 60 to get to rpm's (rotations per minute).
