I was doing a bit of plumbing today and mine is Teflon tape. What a simple, effective invention for sealing shower head threads!
Obviously oil is another!
Ball bearings are a third one for me. I just think of all the things out there that need to roll or move.
Last one for now is springs. All the different types of springs. Running old clocks, closing doors, suspensions on cars, etc.
What impresses you?
