how's it made? if you dont mind be asking

You are joking aren't you?

simply brew from sugar + nutrients. There are packs available that contain all the nutrients and high yield yeast to get up to 20% - 24% vol in 24 to 48 hours, if you require 100% vol the distill up to the azeotrope point at 96% vol and then throw in your zeolite molecular sieves (4 angstrom I believe) to mop up the remaining water.

Ethanol also comes by catalysis from LPG in the vapour phase.as does Methanol.

Not exactly something you can do at home though! Well not without some serious investment in design time.

You might want to electrolyse a concentrated solution of strontium chloride to obtain either the chlorate or perchlorate of strontium. Bear in mind however, that strontium chlorate is less stable than potassium chlorate. This will have some safety implications.
You could add an excess of sodium or potassium carbonate solution to strontium chloride, then filter, wash and dry the sparingly soluble precipitate of strontium carbonate. Ensure that all traces of sodium are removed if you use sodium carbonate. Then, add a slight excess of the solid strontium carbonate to dilute nitric acid and filter the solution to remove unreacted carbonate. When the reaction is complete, no more carbon dioxide gas will be given off. Evaporate to dryness. What you have left are crystals of strontium nitrate- a useful oxidiser which does have its uses in pyrotechnics.
