How much does it cost to breathe? Turns out, it's not too expensive. Oxygen can be made entirely artificially by electrolyzing water. So most of the cost is the electricity to do so. Factoring in additional costs of water and maintenance, it costs approximately 45-50 cents per day to breathe.

In this video we turn copper pennies into silver and finally to gold. Obviously it's a chemistry trick but still impressive. First we get 30g of zinc sulfate and dissolve it into 100mL of water. Zinc sulfate was made back in our video on making a copper sulfate and zinc battery: http://www.youtube.com/watch?v=Id3tL2iI0Vw If you don't have zinc sulfate or can't make it, you can also use zinc chloride. This can be made by simply mixing hydrochloric acid with zinc metal and waiting until the fizzing stops. ... https://www.youtube.com/watch?v=_g_ml8tAnWE

In this video we show how to make potassium chlorate from potassium chloride by electrolysis. For the anode, carbon, platinum or mixed metal oxide works best. For the cathode, almost any metal can be used but titanium is preferred. The electrodes are simply inserted into a solution of potassium chloride salt and a current is passed through. The anode is the positive connection while the cathode is the negative connection. The current should be adjusted to match the surface of the electrode. For carbon that's around 40ma/cm^2, for platinum 300ma/cm^2, for mixed metal oxide 200ma/cm^2. You can use less current for lower heating and wear but the production will take longer. The electrolysis must be kept in a well ventilated area since it produces hydrogen gas as well as small amounts of chlorine gas. As the reaction progresses the potassium chlorate will precipitate our and the potassium chloride will be depleted. This has the overall effect of lowering the solution concentration. Every so often the salts must be topped up. Saturated potassium chloride solution has a density of 1.16g/mL. I recommend adding more potassium chloride salt when the density drifts below 1.1g/mL ... https://www.youtube.com/watch?v=itAnVJ2vpHQ
