“I was working in my crawlspace replacing a hose faucet when I propped my phone in a ventilation well to shine the flashlight on the pipes I was working on not thinking about the fact it’s a cinder block foundation and therefore hollow. Well, sure enough my phone fell in there.”source ↗
“I’ve tried coat hangers, duct tape sticky side out on the end of a rod, a long pair of grilling tongs, all to no avail.”source ↗
“I stupidly did not have iCloud set to higher memory and the phone has the last photos of my Dad before he passed on it. I don’t care about the phone itself so much as retrieving the photos somehow.”source ↗
“I was removing this Ethernet wall plate and accidentally dropped a screw through the large hole at the top. It fell completely inside the wall. Probably a stupid question, but I tend to overthink these things 😭 Is it safe to leave it there, or could it cause an electrical/fire hazard?”source ↗
