borax or alum\n\nmaybe salt\n\ntry copper sulfate

You could dissolve the crystal compound in water and measure the temperature change and specify whether there is an endothermic or exothermic change.  \n\nYou will need a thermometer.  Be careful as some crystal compounds are violently exothermic when dissolved in water.\n\nAndy

The process relies on the fact that Borax, like many things, is less soluble at lower temperatures in water.\n\nIf you make a saturated solution of Sodium TetraBorate (AKA "borax") using [near] boiling water and then cool the solution down to room temperature, some of the borax will precipitate out.  If you place a "seed' crystal suspended in the solution, it will act as the place where the solid Borax will form as it cools, producing some rather nice crystals.\n\nA very similar process can be used to make Salt and/or sugar crystals as well.\n\nBy the way, Borax crystals are NOT edible.  Boron (which is contained in Borax) in definatly not something you want to get in your body, it can kill you.

1-. NaCl + H2O Sodium Chloride ( table salt )\n2-. NaSO3 +2 H2O Sodium Sulfate ( or sulfite I always forget which is the 3 and which is the 4 )\n3-. NaC2H3O2 + H2O ( I'm guessing.  You will want to check your periodic table for the charges on this one )\n4-.NH4Cl + H2O.  Ammonium Chloride\n5-.NSO2 + 3H2O\n6-. not sure\n\nI presume you are working salt solutions.  Ammonia was never my strong suit. I'm positive about the first two.

You will need to use sugar in your mixture to grow your stuff.\nHere are 2 links that have recipes.  One uses sugar and beef bullion, the other uses just sugar.  \n\nhttp://www.umsl.edu/~microbes/pdf/homemademedia.pdf\n\nhttp://www.hmhbwa.org/~hmhb/pdfs/BugsInBod_GrossGermsExperiment.pdf

Gemstone quality crystals can be made into jewellery and so are vauable. Others are useful for their ores (hematite Fe2O3 iron ore, malachite copper ore etc.) I also heard somehing about using crystals for resonance but I'm not sure what that means lol hope this helps\n\nP.S. Quartz ie. silicon used for glass

It's not just lightning, nuclear weapons testing in the past has left behind glassy sections of the desert. To duplicate it, make you're own lightning (electricity as you said). Sand doesn't conduct well at all so you're going to need a lot of it.\nThe easier way is to get an oxyacytlene torch and melt the sand. Crystals are formed from liquids when they are cooled down; the slower the cooling the cooler the crystal looks. In this case you'll need a lot of patience as the meting point of silica (sand) is around 1600 degrees C (additives like sodium carbonate will lower this to a more workable value) and it will take a while to slowly bring the temperature down to normal. Make sure you put the sand on something that won't melt ().\nNot really a do it yourself home experiment.

GREAT GREAT way to get your vegetables, but one of the big things is WATCH the salt intake on the bottle. There is a lot of sodium in that V8. Just drink water too, during the day and THAT, my friend, will keep your salt in check.\n\nThanks! \nSee ya!\n\n--Joker

ephedra is back on the market, it's been back for a while now. but places like gnc don't carry it. Look to smaller health and nutrition joints

PBS usually comes sterile and it has a salt balance that can prevent any hyoer/hypotonic situations, but it is not always used to make growth media. Actually, I have used PBS in molecular techniques, but never in making media.

I'm not sure what the black silver salt you're talking about is, but yes, you can produce Ag(s), the metal, from a silver salt. You need something that will oxidize, so that silver will reduce to Ag(s).

SMALL CRYSTALS\nYou need to warm 100cm3 of water and add 39g of potassium aluminium sulphate (alum). Stir until no more crystals will dissolve.Pour this saturated solution into a large evaporating basin and leave for several days to crystallise. \nGROWING LARGE CRYSTALS FROM SMALL ONES\nMake a new saturated solution of potassium aluminium sulphate and allow it to cool down. Place the dish or beaker of new saturated solution in a place where the temperature will vary as little as possible.Using forceps, pick out the best potassium aluminium sulphate crystal from the evaporating basin.Drop this into the cold saturated solution and leave it for a few days.Using forceps, turn the crystal every day so that it can grow equally on all sides.The secret is to keep the solution in a place which is no warmer by day than by night. An alternative method of growing your crystals is to tie a piece of thread around the starting crystal, then suspend it in the cold saturated solution. Leave in a constant temperature environment. (Alum crystals grow well using this method).You can grow crystals around a wire shape which can be suspended in the saturated solution. Crystals form best on rough surfaces, so use cotton-covered electrical wire or plain wire wrapped with thread or light string.

Crystal growth can occur at about any speed, but if you want a regular single crystal, the slower it grows the less likely are defects. Sudden growth leads to snowflake-like dendrition. Certain minerals like e.g. diamond require some time and extreme conditions to crystallize.\n\nWindows for IR purposes can be either defined minerals or glasses. While glasses are formed by undercooling melts, for some mixtures that might take longer.

How about an experiment to see whether talking to a house plant really stimulates its growth. Is it the words or is it the carbon dioxide from his breath?\n\nYou need two sets of plants that are identical. You need one to be exposed (by loudspeaker) to the sound of his words and the other to have him up close and breathing on it while talking.
