This video refers to "How fast is a Fidget Spinner?" by Matt Parker (https://youtu.be/OWCAlJ1vsqc) adds two things:
1. A method to measure the rotation rate of the spinner when it is too slow for audio analysis
2. A way to demonstrate gyroscopic precession and why it did not work for Matt.

Veritasium explanation of gyroscopic precession:
