Find a magnet and some steel screws. For 1 minute, see how long a chain of magnetically attached screws you can make without the other end returning to the magnet.
Safety tip: The people in B&Q don't like you taking the screws out of the boxes, and neither do other customers.
#Linguistics question! I have an older relative - who would have grown up in Nova Scotia in the late 1940s and through the 1950s. I don't know if it's a generational thing, or a #regionalism, or what, but he uses a term I've never heard anyone else use. Might be only one tiny area; little towns were pretty isolated back then.
"[A] new study, published in The International Journal for the History of Engineering & Technology [revealed] that the Crystal Palace is the earliest known building to use Whitworth screw threads, later known as British Standard Whitworth (BSW), the world’s first national screw thread standard."
Dear screw geeks, can you help me identify this type of screw? I am screwed! I really had some fun losing one and — seriously, I need a replacement now. The magical world of Newton... I prefer having fun with electrons and bits instead. This is the one single use case where AI might come in handy.. besides identifying flowers, identification of screws...
Screw My Heart (2); Another high speed shot, like the one I posted yesterday, using flash duration, triggered by a motion sensor. This one though is more disturbed. I like the movement of the screws here, but unlike yesterday's, the shape of the heart is fuzzy and hardly discerned. I think if you look from far enough, you would notice the overall heart shape.
Screw My Heart. Cutting out my archival posts for today to post something recent. Inspired by my social failures on the emotional plane, I've worked with this project for the past 2-3 weeks whenever I had the time to (and actually still planning to work on it). It is high speed photography but based on flash duration and not on the HSS option provided in the speedlites. It was a challenge since I was limited to only 1 flash head, and had to work in darkness. I had to trigger the speedlite using a sensor; first I used the sound sensor but apparently sound was faster than the motion of the screws (as I hit the desk to scatter the screws), so then I decided to use the motion sensor, which was so-so, but really hard to work with. I made 2 shots so far, and maybe this is the best I could do for now. We'll see later!
Some discernment needed here to see the bounce of some of these screws, kinda!
Edit: IT'S OUT! Screw that screw! :D Thanks for all the advice and support. In the end, a huge amount of WD-40 did the trick, so I didn't have to do more drastic measures. Still good to know for next time. ^^
Original Toot: DIY elephants, can you help me out? How do I get a screw out that sits really REALLY tight? I want to remove some sort of cup holder thing in the bathroom that was screwed in by previous tenants. It looks like it hasn't been moved in a century and doesn't want to start with that now.
It's also very close to the wall, so it's hard to get a grip to begin with. And it doesn't help it's a slotted-head screw either. And yes, direction is correct, should be the same as the other two I managed to remove eventually. ;)
I have an electric drill but would need to buy the right screwdriver bit first, (and I am not sure it can get close enough to the wall for this.)
Would WD-40 work or just make this screw even more slippery?

threaded #fastener which can be 
tightened or released by applying twisting force to the head. They are used to connect two or more materials, products or workpieces. 
They're the backbone of assembly, providing stability and reliability.
