Bunny ate balloon

[Haru the Lionhead]

Hey guys
My cousins rabbit is a one year old four pound angora. She was playing with her balloon when it popped and she ate a part of it and it’s not small.
We gave her digestive tablets, hay, and water
She’s eating a bit but refuses to drink
She ate the balloon two hours ago
She’s pooping a bit
How long does she need to be observed
And when do I know that she’s 100% okay

Well, by now it's several hours later, right? Are you sure she ate pieces? By now, is she eating normal, drinking, comming for treats, and acting normal over all? If no, if she refuses food or just eats a little of certain things, if she's more quiet than usual, lying around and not moving much or any by her own, or sitting loafed up in a quite place - then I would be off to the vet ASAP, there is no point in wasting any time since things can spiral out of hand quickly, if something is wrong chances are better the sooner the issue is adressed.
