Celestia’s horn is way too long for her to actually be able to do this.
Also her hooves are so atrophied after 1000’s of years of non-use she wouldn’t be able to handle the bottle.
(Fun fact: Celestia has never picked up anything with her hooves in the show, except in a picture of her eating cake published by Gabby Gums, which was clearly photoshoped.)
Who can spot the hidden joke? Pony makes me learn about the weirdest things.
You can’t put caps back on glass bottles. Also, plastic hasn’t yet been invented by horses.
Thank goodness our horns still serve as bottle openers.
