It's also possible that the sides of the bearing are tapered. These would fit very tightly indeed. I remember years ago, undoing a tapered steering joint using severe hammering, getting it free, then accidentally letting the two parts join again without any pressure. Yet more hammering!

Proteins are toxic because of their structure and conformation. Exceptions could be the metallo proteins where a toxic metal is bound to the protein, but that is the metal being toxic, not the protein. A denatured protein could be toxic if the shape is correct/incorrect, they still have a conformation, albeit a different one to normal.

They will stay in the water as chloride salts. However as Endy states, this is going to be pretty slow to get significant amounts or a very large still.

Make it a solar still - even better.

Check out what they are doing in Iceland, geothermal is quite well established there. Yellowstone would be an ideal location but I suspect your National Parks would object to a power station sucking away all their heat.

Hydrofluoric acid will dissolve quartz, ( and glass - I used to work in a lab with windows etched by HF ). You do not want to play with HF.

Magnesium don't react violently with water at room temperature, you will get slow bubbling over an hour or so.

You have cracked it! Really hard to control the exact pH.

It has been postulated that prions enter the blood stream in this way. Don't have any references though.

I'm afraid you will just have to try it and see. It all depends on what is in the tank making the pH high. Just do a test with a small volume and see what happens.

I would use BBQ charcoal, much cleaner. A fan to blow air through and you are away.

It's a test for chloride. Check out the solubility of silver nitrate and silver chloride.

You could explore molecular sieves or silica gel. The correct pore size would remove water, leaving the glycerol. The water could be reclaimed by heating. I've also seen a reference to crystallising the glycerol out by freezing.

Not sure but just try it and see. Strongly suspect that as long as you have Mg ions present it's OK.

Not 100% sure about the chlorine being produced, it's most likely oxygen. I'm afraid I'm a bit hazy now about electrolysis. Try and work out a method for testing these.

Raider5678, I don't think you missed anything. That 'someone' doesn't know the difference between types of radiation and in general doesn't know much about cooking food, they are talking rubbish. As an aside:- do the people who are worried about it use mobile phones? You can always fight back by saying they use radiation.

Check out Wikipedia. Habitat loss and persecution seem the biggest threats.

Just had a look at the Brita web site. They say that their filters will remove some of the salts that cause hard water, i.e. they have some ion exchange capacity. Taking out calcium carbonate would certainly drop the pH. Looks as though they are doing what they are supposed to do.

If you are using a single D cell, I don't think you can generate enough of any thing to be seriously worried. The hydrogen will disperse pretty rapidly in an ordinary room. There is no chance that you could breath chlorine gas and not know anything about it

The activated charcoal could be removing some of the proteins from the water. These could be buffering the water to some extent and dropping the pH. 'Pure' water tends to have a slightly low pH because of dissolved CO2. You have given me an idea, I want to remove proteins from my koi pond, they are causing foam on the surface. Brita water filters may be the answer.

A soft spring and a heavy weight. I think it would be best to try and scale up as far as practical. Maybe use a lot of elastic bands to get something a couple of meters long, then put a 100g weight on the end. That should move a reasonable distance at speeds you can measure. Either measure it optically or with a coil.

If you were an electron wanting to get from A to B in the shortest possible time, which way would you go?

Just that 10% SDS need not be made up volumetrically. You are not going to get much difference in action between 9% and 11%, I used to make it up 10g +-0.2g in 100ml water.

Forget graphite. Apart from being a very dirty material to work with, ( think lead pencils ) it is also combustible. So not only would you get filthy, your furnace could catch fire Ceramics would be a very good choice and also readily available - wall or floor tiles. They are also pretty good insulators, so will keep the heat in. You can use ceramic tile adhesive as the cement.
