Take two pieces of string with wooden knobs at the ends and hang them up together.
Put your arm between them and pull down quickly.
Repeat, and notice how a fraction of the time those wooden knobs may wrap around each other and become tied by a knot held by the downward force of your arm until you pull up which you can’t do if you’re hanging.
I mean, why would you want to punch any wall.
But yeah, whoever went through this wall got lucky it wasn’t as solid as its facade.
