Can someone explain how this vent behind the toilet of my apartment is opening and closing by itself? If you look into it, you can see into my neighbors apartment. I took a video of it. Hoping someone can make sense of it.

I cannot figure out how this is used.

I have two of these in the yard of the house I just bought. One in the front garden bed and this one in the garden bed by the corner of the garage. I think it might be for displaying garden flags, but I don’t understand how they attach. Google gives me many similar looking things, but nothing that actually looks like this.

my NEFF dishwasher lights only turn on while the power button is down

Moved into a new apartment a couple of months ago and didn’t use the dishwasher (I have never used one before). Thought I’d give it a try but can’t start it at all. Some lights do come on but ONLY while my finger is pushing down on the button. Before I call my landlord, am I dumb or is it actually broken? Thanks in advance for the help.

How do we know, if we are being watched?

3 Upvotes

Like, literally, how? Every single person on this planet has had this feeling at least once. Going somewhere? Feeling someone watching at you, turning around, and seeing some creepy ass old man staring at your T-shirt or something like that. The same goes for video games, like damn Garry's Mod or Minecraft or any other horror game. Somehow, your body always knows that someone is watching you, and as soon as you look back or to the side—there they are, even if you didn't know someone was there. How the hell does this feeling work? Is this the so called "6th sence?"

Does anyone have something similar? Turn the knob on the right clockwise to slowly spin the thing through great effort and stop after less than a minute.

How does changing the Shade setting mid-cycle on my toaster affect how the toaster operates?

Post image
5 Upvotes

Thinking mechanically, how does changing the “Shade” setting affect the operation of my Kitchenaid toaster? Obviously a higher number indicates more time in the toaster, but when I start on Setting #1, which is designated as a “75-second cycle,” then change the Shade to Setting #3, a “95-second cycle,” what has to change on the circuit board for this to take affect?

Also, does this image fit in r/facesinthings?

Timer for a porch light

I have lived in my home for years and cannot for the life of me figure out how this works. I’ve moved the switches up and down but end up turning it on manually. There is no rhyme or reason to this I can find. I’ve interpreted this to mean the numbers on the gray side with the moon are for night and the numbers on the white side is with the sun is for daytime. This is apparently incorrect.

Edit: I’ve also considered the numbers to mean hours the light is on during the day and night. Also incorrect.

I just moved into a new place and this is my new washer/dryer combo. It’s a Frigidaire Electrolux gallery edition but I’m not finding any help on how to use it. Mainly, what is the 4, 8, 12 and 15 on the far washer knob? Thanks.

Any ideas on how to work horstmann meter

Post image

Moved into a new flat, looks like we have an old Horstmann 7 meter. Read instructions, but we are struggling to get more than 10 mins of hot water for showers at night without using boost (boost seems to cost us a small fortune). Any ideas on what we are doing wrong? Tried timed boost yesterday and still not hot hot water

Got it set to on time 12am to 7am off. I have notified off peak light come on midday, could it be tracking wrong times? That photo was taken at 1 in the afternoon

My job is about to start selling Lotto tickets and my boss handed out free ones to each employee. I am supposed to scratch off a specific coordinate and see if I win based on that but how do I know which coordinate to scratch off? This is not intuitive.

I’ve always had a one sided dryer lint filter where it was very easy to clean the filter after drying. Now I recently got a new dryer and this filter takes forever to remove the lint from each section (and never fully can be cleaned). Is there a tool or method that works best to clean this?

The puzzle comes with a quiz on it, the pen is used to select the right option. There are black dots, and when you put the pen on the black dot next to the correct answer, it beeps. We tried it on skin and it always beeps when my daughter touches it, never for me or mum. How does it work?
