Ever since I can remember, I have been terrified of alarms and I have no idea why. It's not a fear of what they signal, it's a fear of them. When I used to hear any kind of alarm, including the high-pitched low battery sound of our old laptop, I would break down and cry for close to an hour, sometimes more. It's not as bad now, but I still have small breakdowns every time I hear an alarm. I tried buying a nest, the kind that talk instead of beeping, but that's even worse. Every time I hear it speak, I go into the same automatic panic. Why do I have this fear? My parents tell me I have been afraid of fire alarms since I was a baby, but the dog was always there to comfort me in the past, and now he's gone I don't know what I can do. Please help.

I have a fan that says "to prevent serious injury and electrical shock, do not use in window". Why is that? Thanks!

I am looking for a light or anything else that has something in it that will detect and track motion, and point a light, camera or whatever at the moving object. It needs to be relatively small (enough to be supported comfortably by a small cat, don't ask why) and preferably in the $50-$100 range. I have tried searching online but have come up empty. Also, I need it to be able to be powered by standard batteries (AA, D, C etc) thanks!

Trying to remember. It was an old man having a heart attack and falling in a pool. I think coldplay was in the background.

I have a chunk of sodium metal that is not covered by anything. It is already starting to sizzle. Will it explode in vegetable oil or will it be okay to store it?

I'm sick of these updates. How do I change my picture? I know they said in early 2015 that you would "soon" be able to change it, but that was over a year ago. Are they really that lazy?

I built an EMP jammer using about a quarter inch spark gap on one side of the coil, about 20 turns magnet wire, and the power supply for it is 3 AAA batteries fueling a 600KV generator. My question is this: at a distance of approximately half an inch from the target, how much voltage is the coil pushing into the circuit? I already fried my oven, mouse, and power bank with it.

What could I put in the pool that would not harm anyone, but completely green up the pool temporarily? I'm pulling a prank. SERIOUS ANSWERS ONLY, PLEASE.

I spilled some ammonium diuranate, so I put a few grains in the trash. I know the radioactivity isn't a problem, but will there be a hazard of inhalation if I stand near the bin? Thanks for the answers :)
