I'm guessing it makes worse business sense to just sell lighter mono hydrate!

still waiting on the magnet ;)

Hey Nile, can you please show how to make diamonds out of carbon in one of your next videos?

Paul Anguiano

Yes, I was going to comment that I thought the chemistry here was analogous to plaster of paris, so the monohydrate characteristics seemed to be what I would have expected.

You thought this was going to be easy didn't you

Russ Lewis

So this may sound a little odd and really belonged after you burnt up all your beakers but when you place a beaker in front of the camera you always have it turned around so the lettering and marking is in the rear. It makes sense since when in the foreground it just wouldn't shoot well on camera. My suggestion is that the next time you get beakers see if you could get them printed in reverse. That way your logo and all the markings appear correct on camera. Plus it would be a unique feature to you glassware. Which btw you should be marketing if your'e not already. Beakers and flasks make for neat merch . Just sayin

Watching you break all those appliances was pretty funny, but you should check out a ball mill. It's for this kind of thing exactly.

Learned watching Tysy that food-grade oil is used to protect food-grade metal cookware from moisture. Restoration channels use a process of heating steel to ~300C and dipping it in oil to get a nice anti rust coating, and it works as well with canola oil as mineral oil. And that's a lot like what you're doing when you season a cast-iron pan too.

Man, I kinda wish you distilled some of the water after you collected it to get an idea of how much stuff was dissolved into it. I doubt there was a lot in there, since the whole collection process was basically distilling it, but clearly enough of Something could make it through during the third run, and I wonder what else was in there.

Joseph Goins

what? Yet another you-tuber selling bathwater? (HA!)

Mono Keras

By the way, what a nice brand new heating mantle. You've gone a long way from the beginning, haven't you? :p

Nile Red

I made sure to clean them well. However, I still won't use the powder in any reactions or to dry solvents.

Nile Red

As it picks up water, it eventually will turn back to the heptahydrate. It would turn into a huge chunk because the heptahydrate would crystallize together.

Al Myracle-Martin

That was a really interesting video. At the end, when you were showing how hard it got when water was added, if you continued to add water would it eventually turn back into the heptahydrate? And, if it did, would it then just be a huge chunk of magnesium sulfate or would it still be a powder?

Mono Keras

Magnesium sulfate monohydrate is used as a desiccant. You can pull water off ether or other organic liquids using it. It’s fairly efficient, precisely because it can capture so much water, though not as much as sieves. It was a bit silly to try and extract the water in a single batch. As for tasting it… No aftermath? No collywobbles? :)

If you didn't know already, galvanized and black iron pipe tend to have oil on/in them to protect them from moisture, might be a problem with contamination in the future.

Nile Red

yup!

Nile Red

Interesting, I never found anything like that. It could be true tho

Daniel Blake Shoemaker

Hmm interesting getting water from that chemical. When i do chrome plating I use Magnesium Sulfate with Sodium dichromate to plate steel.

Ancient water!

Kevin Martin

Your flask probably survived the second cooking because the contents remained in powder form and so could shift to accommodate the contracting flask.

Hubert Hoefsloot

Now I understand what may be the difficulty with using a salt as heat storage medium. Would be a nice experiment to see how much energie you could get out of the dried salt when you add water to it.

Kevin Martin

That effect of hardening after adding water, right at the end, is very much like what happens with plaster of Paris (calcium sulfate).

I always get weird looks irl and blocked online when I ask strangers to sell me their used bathwater. I should have known to ask you first!

Paul Fisher

What do you plan on using the magnesium sulphate for?

Hey, Great video as always. NB @20.18 your two larger volume labels are the wrong way round ;-)

Monsyne Dragon

This reminds me of one of my earliest chemistry demos in school, showing that Sodium Thiosulphate incorporated enough water in it's hydrated crystal structure to actually dissolve the salt. Was very fun, because the resulting solution readily supercooled, and would suddenly recrystallize rapidly.

Michael Aichlmayr

Some long time ago, I read somewhere, that MgSO4 starts decomposing very slowly at 400°C and the decomposition speeds up as the temperature is increased until 1124°C where decomposition essentially becomes a runaway reaction. Wish I knew where I read that.

Marta

Fascinating! I honestly wonder if the water has a laxative effect, like the salt it was taken from.

Alexander Kirk

Ah, if I may correct you, Nigel himself termed it "Chemist Boy Bath Water".

Do patrons get a different drawing for the water?

Nile Red

Unexpected, but still good I hope!

This was not what I was expecting when I got the notification

Nile Red

Yeah, that's probably true. I wanted it done fast though and I didn't want to wait for the ball mill. I also didn't want it to be too powderized because I was worried it would fuse again in the flask.

Nile Red

That's true, I just didn't expect it to be such a pain.

Jacob Osgood

And you could make a DIY ball mill out of stuff you could get at the hardware store for less than you paid for the food processor.

Jacob Osgood

@12:15 Oh NR, you should know better to send a chemist to do an engineer's job. Drill in a few relief holes, and sink in an expanding bit, a heavy taper screw, heck even a punch would direct tons (literally) more force on a much smaller area than your whack-a-mol stick.
