Looks like you didn't read the PM I sent you the last time you asked about that (and now you're subsequently spamming the forums...
), so I'll reiterate here:
When people play a hack, typically the main thing they're taking away from it is how much fun they had in the hack, or perhaps a few key concepts from it that made it particularly enjoyable to them. Unless it's a hack they've played countless times and memorized by heart, most people aren't going to know exactly what hack you're trying to find based on a brief description of an extremely specific part of a specific level.
I will say though, the fact that you don't remember much about it aside from these minor off-hand details gives me the impression that you weren't that huge of a fan of it either. Instead of trying to find a hack that you saw on Youtube once years ago (as you told me in PM), why not just play any of the other outstanding hacks in the sections here, if you're just looking to have a good time?
Science teachers are too afraid to teach their students about the element of surprise.
