Turn on JS or check what's causing it to fail to load. It's a little JS physics toy of this XKCD comic. https://www.explainxkcd.com/wiki/index.php/2347:_Dependency

The whole "Disabling JavaScript and then pretending to not know why websites don't work and then acting holier-than-thou about it" shtick gets old.

You know sites will break. Could you just cut the bullshit with pretending to not understand broken websites?

Truly baffling, you're voluntarily disabling a critical piece of how websites expect to function and then act shocked when web sites don't cater to the >>0.0001% of users who decline to allow their site to work.
