I just remembered something.
I think I saw something really interesting a while back.
I had a field trip to the Ho Chi Minh trail museum a few months ago.
So I was supposed to go with everyone but decided to wander off on my own.
I got to the second highest floor of the museum and the whole room there was pitch dark.
The door wasn't locked so I decided to go in and see what's inside.
There were a bunch of exhibits there in glass containers, just regular stuffs, nothing special.
But then I saw it. It was a very old looking table phone and I kidd you not, it had cherry MX switches. Some of the keycaps of the phone was missing so I could clearly saw it. Too bad it was in a glass container so I can't try it out. There wasn't any sign or any descriptions for any of the exhibits there either.
