Everything screws in and out, except rotating that rotating arm which slides freely in out. A: Bicycle chain tool

What is this steel wire, with a smaller gauge of wire wrapped around it, used for? Magnets are attracted to the metal, and it’s harder than aluminum (both core and wrap) so I’m guessing it’s stainless steel. A: This looks like what you have Lead sealing wire. Used with security/tamper seals.

WITT: clear, shiny film. Disintegrates when I touch it. Has no smell. Almost looks like tinsel. A: It’s either a slug or snail trail

A resin cube that contains a liquid that says “Mesa Petroleum Transaction” & “100,000,000 October 1979”. I assume it’s oil but Why, what, and, who lmao A: Commemorative oil drop from a business deal or milestone

Removable stair shelves in older home on second staircase (seen on Zillow). What’s the purpose?

This rubber button in my 2007 Ford Focus mk2 1.6 petrol. Seems to be important as there is a blank on the opposite side. A: It’s a fuel shut off reset button/solenoid. Should you be in a crash it activates and won’t let the car restart until it’s returned to the position it was before.

They are small and plastic with a piece of plastic inside with no hole in it, almost like a plug or a stopper or some kind. A: You can keep the cig in your mouth without smoke going in to your nose and eyes, so hands free. I used one at home when I smoked in my 20s. I wouldn’t want to be seen at the bar with one though.
