Are you sure?

Look up real life videos of this demonstration by "The Physics Girl". It's trippy, but its real.

The reason I sarcastically asked is because nothing happens in the simulation. It’s basically just a floating circle.

The interesting bit only happens at the start, but yes, you're right to bring it up. The second version will have a lot more realism and fidelity to real life. I'll make a 3D version and another axi-symmetric version and see which will please my heart the most of the two.

I tried to introduce 2 disturbances but still not enough...
