Maybe not projectile vomit but they absolutely could reverse peristalsis just like any vertebrate. Giraffes chew their cud while upright after all. Peristalsis is agnostic to how high it’s pumping, since there is no functional loss in strength.
Comment on They did the math.

Are we sure they could vomit?

AFAIK Horses cannot vomit, and I also was told that mice and rats cannot vomit.

What I’m describing isn’t actual vomiting either, but more like regurgitating. Rodents can do that, though horses can’t (because they can’t even belch, they’ve got a one way valve).
Ruminants like sheep and giraffes also don’t externally vomit but they do internally vomit which makes stuff change chambers in their stomach.

Somehow the last part seems worse than vomiting. I know it isn’t, but eeww.

A question I never thought I’d want to have the answer to.
Do birds vomit?

They feed their young through regurgitation so they do have the ability!

not sure, but 2 seconds is thinking about living animals tells us that that would probably bend over first.

And 2 more seconds and you start wondering how many pints it would take.
