Can you burp in space?

Burping is how the body clears excess gas from the upper digestive tract.

In space, gravity helps separate the gassy ingredients of a burp from the liquid and solid remnants of food in the stomach.

Without gravity to sort out the contents of your stomach, it's all just one big chunky, gassy mess.

Gas that makes it past the stomach and into the intestinal tract can come out the other end as a fart, which is an entirely different challenge.

But timing is everything, because you need to make yourself burp while you're still accelerating away from the wall — otherwise you'll get chunky bubbles.
