The tech department at my former high school was at the complete end of the school in its own hallway where no one went ever and the teachers down there just fixed all the other teachers broken shit made everything, and did whatever in the world they wanted. They had three 3-D printers and just printed the stupidest but also the coolest shit. There were two of them and they been best friends for who knows how long, they went to high school and college together and I think they knew each other even before then so one would be teaching and the other would be wondering around doing something. Class was often interrupted.
In my middle school we had a very old tech teacher who could build just about fucking anything, and, he must have been 70 years old and 100 pounds but he still rode his motor cycle and parked it outside the tech room everyday. And every class my eight grade year (when he was not my teacher) he’d wander around in the back and bring out whatever we were learning about that day. He took no shits and was the wittiest man I’d ever met.
