The following I did as a student.
Our economics teacher reserved the VCR for our class that day but didn’t bother showing up (or letting the school know that he wasn’t coming in).
So, we had the VCR in the room with no teacher or videos to watch and the school had snipped the antenna at the base so it couldn’t be used as a TV.
Some guys tried to attach wire hangers and other stuff but nothing worked practically and we couldn’t get good reception.
Then I had an idea. I got a washing machine timer from my locker, unwound all the copper wire from the motor, and strung the wire back and forth a couple of times from the screw hole for the antenna to a lightning rod right outside the window.
We watched Tom and Jerry for the remainder of the class.
