Choose beyblade as the topic for my physics project, need help.

"Rotating Object Dynamics"

I need to make a PP presentation and an experiment. Problem is I don't know where to start. Physics masters, could you give me an entryway as what is a good topic to start researching? I'd appreciate sources that you find great.

I know I should come up with this part, but can I have some inspiration on what kind of experiments I can showcase?
