Astronauts cannot burp in space.

In space, astronauts can cry, but their tears don't flow down their faces. Without gravity, tears form a liquid ball that sticks to the eye, gradually growing larger until it spreads across the nose to the other eye or needs to be wiped away with a towel.

If you were to cry in space, the tears would form a bubble in your eye until it's so big it moves to another spot on your face.

Buzz Aldrin’s mother’s maiden name was Moon.
