Should read whatever contract you sign. There's almost certainly a provision for how your blood is handled. It's mostly to keep people from thinking that the place might give your blood to someone and put it in a database or whatnot, -but- it also serves as them letting you know you aren't getting it back.

Edit: Just remembered some places do infact keep your bits after testing, but that's for like when you provide your blood to a research project, not like STD tests or whatnot.

No, you gave it to them to be tested.

Non toxic is more or less a much lesser version of food grade, but really, its not the same. It means that there are no known toxins in it, but it hasn't been treated, packaged, or intended as food at all. As such things like resistance to growing bacteria/mold on it aren't taken into account. There's also not really any regulation around what constitutes non-toxic.

Basically while you probably don't have to call poison control for your kid munching on play-doh, you also probably don't have to call them if they eat a spoonful of dirt.

It's not a good idea at all to let them do it, and can lead to digestive problems, but it also isn't like they ate like... Windex or something which would need immediate medical care.

You would be surprised.

Back as a kid I tried to make an FM transmitter and it turned out to be a cable TV jammer instead. Worked at a range of at least 100ft on a 9V battery.

Enough power and that signal will work it's way past the shielding in wired connections. Not nearly as much range though.

Try and propose a different metric. Guarantee it's basically impossible to standardize.

We use mileage cause it's all we got.

Gas not glass.

Actually yeah, it's that simple. Like say you take some aluminum cans and melt them in your backyard. Some of the inks and plastics burns off from the heat. The oxides float up to the top and you can scoop them out. What you pour out after is basically clean aluminum. Big industrial process are bigger, but functionally the same. They just pay a bit more attention to not letting oxygen contact the molten aluminum to prevent unnecessary oxidation. There are still some non aluminum impurities that get in there so you can't make a lot of alloys out of it, but it's plenty fine for lots of purposes like aluminum foil and cans and stuff that aren't like making up the wing of an airplane.

The dross you skim out is mostly it's aluminum oxide, but also contains a large amount of metallic aluminum that followed along for the ride. Depending on the initial melt composition and handling it can contain anywhere from 15%-85% recoverable aluminum. That can be recovered by mixing it with molten salt fluxes. This allows the metallic aluminum to separate out while the oxides mix in with the salt in a separate layer. You get an even worse grade of aluminum out due to the large amount of flux used, but again it's still useful for lots of stuff and the whole melting process takes something like 90% less energy vs processing raw aluminum oxides. The extra contamination from the salt flux is why you don't just toss in a bunch of salt in the first place.

Afterward once the salt is loaded up so much that it isn't useful as flux anymore is allowed to cool and is pitched as trash. It's called salt cake, and is actually a decent bit hazardous. Disposing of it safely is kindof becoming a problem actually.

Spring water is usually naturally filtered by passing through porous rocks on it's way out. In general it's gonna be cleaner than water from a river or a well, but of course not all springs are equal. Often you get delicious minerals dissolved in it which can be touted as "healthier" but mostly just taste different. Sometimes you get harmful compounds leeched into it. And the actual collection point usually isn't a rock, the water generally pools somewhere, it collects in a groundwater reservoir where bacteria can get into it.

So basically you still want to test a spring regularly to see if it's safe, and filter/boil it if you don't have the ability to test it.

But you know. If you are in a less developed place, and more or less already adapted to ordinary bacteria there, a spring in an elevated area that doesn't catch runoff is gonna be about the best source of water you are gonna get.

Your Garmin probably tends to run a decent bit cooler than a cell phone. Or like at least a modern smartphone running a game. I've had my phone gets pretty dang hot before.

Though I'm also pretty sure if a phone MFG wanted to they could figure out how to make an ambient sensor work with reasonable accuracy. Probably just not worth it though

So that makes monopoly money different than regular money? It's that monopoly money is really easy to reproduce, no one will stop you.

With government backed money the thing stopping you is the government. They arrest you if you try.

With gold the thing stopping you is the ability to dig out more.

With cryptocurrency the rules are enforced cryptographically through any number of different algorithms. That basically means that more or less anyone can create a bunch of rules for how their new currency can be used, traded, etc without needing to be a government.

The trick then is convincing other people that your idea is worth it as a currency.

Spacecraft need to eject mass to move forward. Essentially they are pushing off parts of themselves, and leaving it behind.

That mass is often burnt exhaust gasses from rockets. For small adjustments they tend to use compressed gas directly since it's easier to control. No need to constantly start and stop a rocket motor.

Being rigidly attached to the 6.6 sextillion tons of planet earth does tend to diminish the magnitude of the change in motion though.

Well the thing about balance on a competitive videogame is that, even if something is unbalanced that doesn't make it unfair. As long as people have access to the same options, or like in asymmetric maps you alternate sides and play multiple rounds it's fair for competitive use.

What balance is about is making competitive play -interesting-. If competitors see that some character or weapon or strategy leads to an advantage some will gravitate to that strategy. And when too many people do it things get tweaked to make that less advantageous.

The developers do their best of course with play testing before a release, but after they get a ton of data to look at from people actually playing the game. Though generally they try not to make sweeping changes as that can lead to even more things going out of whack. A higher playerbase tends to find things the developers missed/couldn't predict just from the sheer quantity of people trying stuff out.

Also bylaws for many companies specify at least a 2/3 or more majority to approve things like buyouts, or changes to bylaws (which could then reduce the votes needed for a buyout), but leave routine stuff to an ordinary majority. But they'll always leave some room so that a couple percent can't halt an overwhelming majority.

Bruh, you just got the image of the mosquito burger to flash into my head. I would rather have forgotten that forever.

So yeah, now you know that's a thing too.

Dunno man, sounds like a Mac and Cheeseable microwave.

Like you -could- heat the Mac and Cheese on a stovetop, but what else would you use a microwave for really :D
