зрители швыряли гнилыми яйцами в танцоров.
In this sentence, why is "гнилые яйца" in instrumental? I initially thought that the verb takes the instrumental case, but then I checked and found something that confused me more. It said:
швырять деньги/деньгами
Why the choice of cases?
I would be greatful if someone could please elaborate on this. Thanks!
