“A small cover on the sidewalk with a metal pattern, foot for scale” Answer: "It’s a rain and frost/ice detector. A small current is on the 2 metallic circles, they are not touching and are isolated against each other. When raindrops connect the 2 metals, the small current is amplified or switched, so it can trigger a pump or close windows that are fully open at that time and rain or snow won’t damage things."23
“A sliding tray with holes on both sides of this sofa” Answer: "It’s a tray table. It has another piece to it. It’s a tray with matching pegs. The tray goes on top and the pegs slide in. They fit together, so the tray sits tightly. Then you take the tray back to the kitchen and put the sliding part back, so it’s not in the way."27
“A fork with tines of varying width — what is this used for?” Answer: "It looks like a failure of quality control. When the punch came down to cut the slots, the fork blank wasn’t all the way in and was a bit cockeyed. If quality control wasn’t having an off day, it would have ended up in the bin."
