how do you dissolve rocks?

Depends on the kind of rock.  Some of them probably won't dissolve easily -- you'd have to pulverize them first.

get a plastic bottle\nput fins on it\nput in vinegar\nget a cork, cut it down and put a small hole in it.\nput in baking soda and jam the cork in  fast.

With a water softener.\n\nhttp://en.wikipedia.org/wiki/Water_softener

Their are various ways.  One way where i live is by putting large nets to cover the area.  This holds the rocks in place.

Well, you'd have to specify what you are trying to dissolve.  Many plastics are soluble in several solvents... N-Methylpyrrolidone being a good one.  Solvents generally do not attack metals, unless they contain water.  I would steer away from an acid or a base.  Can you say what you're thinking of?  If so, email me at connecticutpoet37@yahoo.com

Use a bong.  Joints are a waste.  Dry bongs "Rock".  Try a dry bong.  After several bowls, scrape the resin out, roll it in a ball and smoke the resin.  YAA-HOOOOOOOO  HOOOOOOOOO\nSMOKIN****************************************************************************************

This is a small barrel tumbler that comes with tumbling grit. To make it work, you should fill the barrel with about 1/4 inch of water, about 2/3 full of rocks and then grit. You want a mix of water and grit that doesn't just wash off of the stones when the barrel turns, so you want it to be a slurry consistency like a paste almost. The idea is to have the grit stick to the rocks. \n\nIdeally, you want to polish your rocks in steps, using progressively finer grit each time, and finally a polishing compound. You start with coarse grit, a second finer grit, a third grit, and a polishing step. Each step may take as long as a week of tumbling. \n\nSand is a very poor tumbling grit, and will take much more tumbling time to produce the same result, plus you cannot use sand for any rock that is not softer than quartz, and many attractive tumbled rocks are some variety of quartz. \n\nHere is a detailed explanation:\nhttp://www.gemservice.com/lapidary.htm

b a solution, the salt will dissolve

Put it in a graduated cylinder, record the water level, drop the rock in, and note the new water level. Subtract.\n\nYay science.

Like Kak says - remove the iron filings with a magnet. Sieve the iron filings to seperate the filings from any chalk and copper sulfate that is clinging to them. Wash the copper sulfate and chalk through the sieve with distilled water.\n\nThe copper sulfate is soluble in water, but the chalk isn't, so add water, stir until the copper sulfate dissolves, then let the copper sulfate solution filter through filter paper into a beaker below. Wash any remaining copper sulfate solution through the filter paper with distilled water.\n\nBoil the copper sulfate solution until all the water evaporates, leaving solid copper sulfate residue.\n\nThe damp chalk powder sediment is left in the filter paper. Scrape it off the filter paper into another beaker. Boil off the water until you are left with a dry chalk powder residue.

rocks are made up of minerals

If you go to gofish.com or myspace.com there is a video about this.  Apparently it is a matter of breaking the surface tension.  They used only 2L bottles but I think it will work with other sizes.  Not only mentos and diet coke works, but they used diet pepsi, with same results.  It even works with dropping rocks in the bottle.  It was a really awesome video, it was quite funny.  I suggest checking it out.

The simple way is to make a solor still. Dig a hole, fill with some salt water.  Take some plastic (big enough to cover hole) Weigh it down around the edges so that it wouldn't move or blow away leave a hint of slack in it.  Put a smal rock in the middle.  Put a can/cup ect under the rock. As the water evaporates it will collect on the plastic, on drip from where the rock is.  Drips fall in cup.  Fresh water.  You can boil sea water and cool steam, collect drips in bucket.

a salt water mix. mix it in a spray bottle. should turn it pretty quick depending on how much salt you use.

Yes.. they use ones that dissolve. It's no big deal.

One that will ideally:\n1) dissolve the component that you wish to collect but not the others. Then you can do a filtration, collect the filtrate and evaporate off the solvent to get back the component that you want.\nOR\n2) dissolve all those that you don't wish to collect but not the component that you want. Then you can do a filtration and collect the component that you want as the residue.\n\nHope this helps :)
