Hello there. I'm in the process of reading a complex text now, and I myself am not really good at Japanese right now (around N5, maybe a bit less skillful even), but I'd like to tackle complex topics, because I believe it'll help me learn the language faster.
Anyway, what I'd like to ask here in regards to this question, is going to follow after my attempt at translation:
Having some weight, it made sounds when I shook it: an unopened cookie jar that, when opened, seemed empty.
I'd like to point out that the context of this sentence is essentially a description of some magical box that can grant wishes. And it also seems unnaturally empty.
I'd like to ask you about the parts in bold. 「振ると」 here is essentially "when you shake it", this is not really difficult. However, the other "~と" part in the sentence, 「開けてみると」, bugs me a bit. It seems I don't understand the nuance in what the 「～てみる」part does here specifically. I'd translate it as "When I opened it, ...[it seemed empty]". However, I've translated this just as I would an ordinary 「~ると」 clause, and I don't think that's right. Also, almost all the examples on Tatoeba list the 「～てみると」 clause as either "When you do X, you find that..." or "If you did X, you'd find that...", and I can't shake a feeling that I'm not seeing some nuance here. Is there more to the last part of the sentence then just "When I opened it, it seemed empty"?
EDIT: Also yes, I should have mentioned that I've researched the fact that 「Vてみる」is "try and see what comes of it", but I'm not really getting how I can use that in my sentence. Also, both 「~ると」 and 「～てみると」are "When I did one thing, another thing followed" or "When you do one thing, another thing follows"? Essentially I may be off here on the point if the main character talks about things he already did (When I opened the box,...), or he describes what could have happened if that was done (When/if the box is opened, ...). No clarity yet on those fronts. Does the と part here include the completeness of the action or stating the fact about what could happen?
Does the last part become
"When I tried to open it, it seemed empty",
"If you try to open it, it seems empty"?
And if second option is true, how does 「だった」(past tense) fit here?
Thanks for all the help.
