I'm going to say no, it should not be reopened, at least not in its current form, though of course I voted to close it in the first place so that's not saying much new :-p
The reason I voted to close it is basically that your question is just asking how some fairly arbitrary thing happened. We get quite a few questions that, like yours, tell us about something that happened in everyday life and ask how it happened. But this site is not a place to get explanations for how random things happened. Here, we focus more on why they happen, specifically in digging down into the underlying physical principles. There didn't seem to be anything about that in your question.
If you had worded your question a little differently, to make it ask more about the physics involved in the situation, it might have been on topic. For example, instead of asking how the soda got out of the can, suppose you speculated that there might have been a tiny hole, and you wanted to know how to figure out what size of hole would allow the liquid to escape in 25 years. That would be a question about physical principles that might be on topic. Or, perhaps you might want to know whether the fizz or the sugar would affect how quickly liquid could escape through the hole. That could also be an on-topic question. Alternatively, you might wonder whether the liquid could diffuse through the side of the can over such a long time. You'd have to do some of the preliminary research yourself, but you could definitely ask an on-topic question about that.
It might actually be possible to edit your question in a way that makes it on topic and eligible to be reopened. Of course, the trick is that you would need to do so without invalidating most or all of the existing answers, since once people have put in the time and effort to answer your question, it's considered discourteous to change the question in a way that makes their answers no longer apply. If you want to do that, you would certainly be welcome to ask for help improving the question in our chat room.
For clarity, let me add that the only thing that determines whether a question is on-topic or off-topic is (perhaps somewhat obviously) the topic of the question. Our site scope is not based on popularity. So things that do not affect the topicality of a question include:
- vote counts
- view count
- asker's reputation
- whether the question is on the Hot Network Questions list
- whether the question is tweeted
