Fake. It's obviously a bagel.
Lots of heat here too I suspect. The deformation is going to be way easier with all that heat from the friction.
Honestly a mesmerizing gif...
I hate when that happens
Wonder if the result would be different if you could somehow get the force applied evenly across the surface.
Yup, looks like it breaks because the string essentially cuts it in half

But... You can see a divot in the center of the wheel where the string is making contact. It looks like it breaks apart because of that new weak point. It's not like I'm being an armchair physics professor, I'm making an inference.
What string? It's a water jet.
You know, I wasn't sure whether it was a water jet or not, since that's used to cut through STONE. So, it's likely that the wheel was being cut in half prior to it tearing apart.
The ones used to cut through stone and steel typically have diamond "sand" muddying the water. At least the one at my local machine shop does. I'm guessing the one in the gif is straight water.
