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.
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.
Is 1500 calories enough for a 5’3 15-year-old who is non-active?
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.
