I heard a proffessor talking about making whiskey pure at home by, if I recall, putting a potato or corn cob in a bag with sugar and submerging it for a week or two, then removing the vegetable and submerging again the rot and sugar mixture for a couple weeks. If done incorrectly or not properly mixed afterwards, it could be fatal, which is why I'd like to know for sure what the steps are if anyone could point me in the right direction. I'm not looking to make a distillery, I just want to know if it can be done so simply. I have heard prisoners do the aformentioned and put the bag deep inside the toilet bowl, but the next family reunion is some time away and I would like to hear from someone else who has done this before.
Much obliged.

Its a two stage process. Ferment potatoes, grain or whatever to make an alcohol. You then ferment the alcohol. The process is pretty much the same whether its vodka, gin, whisky or brandy that you're trying to make.

Keep in mind that home fermentation is illegal in the United States for two main reasons. First, the government taxes spirits. Second, fermentation is a skilled process and many people have gone blind or have been killed by drinking home fermented spirits. Only the middle part of the fermented liquid is safe. The first part (the foreshots and heads) and the last past (the tails) are dangerous. The skill is knowing when the flow of distillate has passed the heads and not reached the tails.

www.aquasana.com.au Aquasana Counter top home water filtration systems deliver the most economical and convenient solution to the problem of ...

I have a natural spring at home (UK) producing a substantial amount of pure water. This water has been tested and is shown to be a very high quality and meets and exceeds all minimum standards as set by the government. I could therfore sell it immediately without any further treatment. I do not know where to start because I have the room and perhaps the money for a bottling plant, but wonder if I can sell to a third party who could collect the water and bottle it off site?? Please help... Thanks

I would think it would need to be bottled at a site near the source, otherwise getting it elsewhere would be a big hindrance with the added need for transportation of the water.

I doubt that you can take this task on yourself though.

Perhaps get in contact with some bottling companies and see if any of them are interested.

This is for a science (specifically Chemistry) lab we were doing. Our teacher brought out a beaker with a muddy mix of water and dirt, telling us to try and seperate the dirt from water and produce as much pure water as possible. We have access to all the equipment at school, like the bunsen burners, beakers and such. He instructed us to create an original way to filter out the dirt. We are allowed to bring materials or supplies from home, although he suggested not to bring coffee filters as that isn't very original... and I have been brainstorming with no conclusions. Any suggestions or cool ideas?

Make a water still. Separate the pure water from the dirt through distillation, either by evaporation (slow) or by heating it to boiling (fast). Have the pure water vapor condense and drip into a clean unsealed flask.

Seal your flask of muddy water with a stopper with a hole in it. Attach tubing to the flask through the stopper. Arrange the tubing so that it goes to a much higher level (try at least 1 foot), then loosely coil it downward and have the open end inside a clean empty flask that is not sealed (you don't want to build up pressure that might explode the flasks, so make sure the tubing is not kinked and the flask is open to air.) Heat the muddy water over a bunsen burner to boiling. The water vapor that escapes will travel up through your tubing and when cooled by the lower temperature of the air around the coiled tubing, it will condense back into water and drip into your clean flask, giving you fairly pure water.

It takes pure water for electrolysis. Bottled or purified.
Should be done only when there is surplus energy, at off-peak hours.

No, because it requires a lot of energy to extract hydrogen via electrolysis. Off peak hours are at night, when there's no Sun to provide power to a solar cell. Additionally, solar power technology is currently not very efficient, so you couldn't get much hydrogen from the process.

On top of that, you'd need a way to get the hydrogen from your house to your car, and a car that can burn hydrogen as fuel.

It's an interesting idea, but simply not feasible.

For example: At 70 PSI (like in your home water pipes), what temperature will it freeze?

PS: I know "pure" water at sea level (or 29.92 barametric pressure) will freeze at 32 degrees F, or 0 degrees C.

the properties of water do change with increasing pressure, however the freezing point of water changes very little unless enormous pressures are exerted; a calculation was done (see
http://www.newton.dep.anl.gov/askasci/ch em00/chem00298.htm )

that shows the freezing temp of water would change by less than a degree if you increase the pressure by a factor of 100, so for home water pipes, the effect of increasing pressure by a factor of 4 or 5 will have no real effect on the freezing temp of water
