Interesting. Regarding the hygroscopicity. So, potential water in the previously aging fluid might have been contributory. Assuming the corrosion was internal, now that the fluid has been aggressively replaced with fresh fluid, that might slow the corrosion down, correct? What commercial...

I had a rear 3/16" OD steel brake line in my car fail due to rust. I spliced out the area with the hole with copper nickel line, but, I noticed that there's areas closer to the engine where the painted surfaces have bubbled a bit. Unfortunately, access is such that I can't splice fresh line...

I'm seeing somewhat conflicting advice for storing supplements long term (longer than 5 years). First, supplements are supposed to lose their potency with age, but, minerals are supposed to be stable for a very long time- possibly even indefinitely. Looking at this list: magnesium glycinate...

It's a long story, but I'm in the process of taking apart 100s of laptops involving 1000s of laptop screws. I'm trying to come up with ways to take the screw off the drill bit, keep it upright, and then weaken the bond enough so the drill bit will pick up again- to put the screw back. Right...

I'm looking for the least expensive method for making food grade zinc carbonate (for a molecular gastronomy recipe I'm developing). I know it can be done with the soluble forms of zinc (sulfate, chloride and possibly acetate) by combining them with sodium carbonate (which I have), but the...

That's a good question. Yes, gravity would play a role if pulling horizontally, but I'm talking about pulling vertically, like the steel in the video.

After being properly kneaded and proofed, pizza dough, if formed into a column and pulled apart, will fail in the center point at least 99 out of 100 times. It may not be homogenously* structured enough to happen 100% of the time, but it's enough to happen almost all the time- and it's the 99...

The fibers in paper might stretch a tiny bit when pulled apart, but, for the most part, it isn't ductile. Here's a good photo of taffy being stretched: https://littlehousebliss.files.wordpress.com/2014/07/taffy-after-pulling.jpg This is typical for taffy and dough- and chewing gum, and molten...

For materials that have a propensity for necking, assuming they're heterogeneously structured/have equal strength throughout and are without defects- why do these materials have a propensity for necking in the center when forces are applied to both ends? I'm trying to use physics to explain...

I'm using it on the rubber seal under a dishwasher motor/pump (between the motor and the plastic bottom of the dishwasher basin), so I can't cut it off. In my experience, silicon caulk has superior adhesion. The rubber seal is pretty old (and impossible to replace inexpensively). My concern...

It seems that the consensus among DIY forums is that the only safe caulk for dishwasher use is food grade/aquarium caulk. For my specific application, though, I need something less permanent than silicone, but, from what I can tell, a food grade latex caulk doesn't exist. I was looking at the...

I have a plastic slinger (hdpe, I believe) that is attached to a dishwasher motor shaft that I'm trying to disassemble so that I can replace it's bearings. The sling will twist independently of the shaft, but it won't come off. I've been thinking of hitting it with a penetrating catalyst (PB...
