What everyday objects become surprisingly challenging to use in zero gravity?

For some other things - the astronauts have to use a seat-buckle - for example, typing on a regular keyboard gradually pushes you backwards until the keyboard is out of reach.

Things like drinking cups really don’t work - neither do hard glass bottles. You have to force the liquid out by squeezing the container and drinking the liquid through a straw..

I’m sure there are plenty of other things.

Why do people have trouble accepting the very true fact that "The Blue Marble" photo of Earth is a composite and therefore (just like every other subsequent "picture" of Earth NASA has ever shown us) not a real photo but computer generated?

Toilets are notoriously difficult - if I recall correctly, there is something like a three day training course for astronauts to learn to use the ISS toilet before they fly there.
