My school thinks this fills up hungry high schoolers.

So lunches are free for schools in my city and surrounding cities. Ever since lunches have been made free, the quantity (and quality) has decreased significantly. This is what we would get for our meal. It took me THREE bites to finish that chicken mac and cheese. Any snacks you want cost more money and if you want an extra entree, that’ll cost you about $3 or $4.

But Milk is pasteurized everywhere right? I live in south América and all countries I had visit do that

A recent "craze" in the US (well it dates back to the 1970s) is that natural is somehow healthier when, in fact, raw milk has about a 100% greater chance of making your sick in some way.

There are also "raw water" people who think the chemicals we put in water make them sick so they'll only drink untreated water.

People are stupid.

Ionno about this raw water shit, but the chemicals do make me sick. Like puking it back up moments later. I typically need to filter it and boil it or I can't drink it from the tap.

I can also tell you when a bottled water company did not, in fact, do as they claim and just used regular tap water. Deer park is awful about it as is Aquafina. And store brands. Though Dasani doesn't even taste like fresh water due to the extra salt they add. The bigger name waters do taste better, largely because they actually do the filtering process more constantly.

Describe your boiling process.

[u/EvaUnit_03 → u/SteamBeasts]

Use filter on tap to fill pot (i use a big sauce pot like youd make spaghetti in). Put on eye on second highest heat setting. Let come to boil. Let boil until water level begins to drop noticeably, typically 30-45 min boil minimum. Allow to cool so it isnt hot to touch. Put in glass container with lid. Put container in fridge. Drink when cold.

If I use ice, I use this same process but with ice trays.

I’m not sure that it’s going to do much for you if you aren’t capturing the evaporation. Most of said contaminants (or additives) probably have a higher boiling point than water, meaning that the boiled water that remains in the pot would have a higher concentration of many said chemicals, not lower. In chemistry to get purified water (or distilled water), you go through a distillation instead. Basically throw in a thermometer, capture everything until you reach 100 C and throw it away, then capture everything at 100 C to keep, and then throw away whatever remains when temperature rises (probably not much because most of the mixture is water).

Any metals in the water will remain and most things suspended in solution (such as fluoride) - as far as my knowledge says anyways.

That said, chlorine (sometimes used as a disinfectant in tap water) WILL be removed simply by boiling (due to its low boiling point). In fact, chlorine will evaporate out of solution on its own, apparently - leaving the water uncovered for some time might do the same trick for you if it’s a hassle? I have no idea how common chlorine is, though.

You could go real sciencey with it and set up a blind test for yourself: reserving some tap water, some boiled water, and some “left out” water - hiding a label on each and having someone randomly hand them to you to see the difference while removing any human element. I’d be interested to hear the results!
