OK Don’t know if anyone would know but how does the astronauts glasses not float off his head?

Impressive video too - Had to download as my connection is not up to playing at 4k…

Friction holds the glasses to his head. It doesn’t take much. If he were to push them off or shake his head violently, then they might pick up enough momentum to drift away, otherwise they will stay put.

Newton’s First Law of Momentum: When Isaac Newton is at rest, he tends to remain at rest unless acted upon by an outside force.
