What kind of crystal is best to use when shattering it with the unamplified human voice?

Doing this with an unamplified human voice is very hard, no matter what you use.  Basically, you'll need the thinnest, mosy fragile design you can find, and a very powerful diaphram.  Did you see the episode of Mythbusters where they did it?  They found a professional singer who could do it, but only after trying a couple dozen different glasses.  As far as what kind of crystal, I'm afraid I don't know that.  But ultimately, this will be much easier with an amplification system.

Here is a nice experiment to try.\nhttp://www.angelfire.com/mo/sasschool/DKScieMatter10.html\n\n"This tasty crystal making experiment is a great way to see the formation of crystals almost right in front of your eyes."\n\nAnother one.\nhttp://homeschooling.gomilpitas.com/explore/crystals.htm\n\n"Crystal Ornament"\n\nAnother.\nhttp://www.yesmag.bc.ca/projects/crystal_gardens.html\n\n"Crystal Gardens"\n\nOne for microscopic crystals.\nhttp://www.science.uwaterloo.ca/earth/waton/crystal.html\n\n"Crystal growing made easy"

its not as effective as you may think, your gonna need to be able to hear the other person over the noise. may i suggest standing next to an older running generator, as the noise both audible and inaudible should scramble a long range mic.\n\nbut as stated above try moving the conversation to a more secure area, be it in a large drainage pipe, or a vehicle. any place is more secure than out in the open

Just water at room temperature, nothing else, any citric would cause temporary damage to the vocal chords..☺

I suggest that you create a supersaturated solution first. Reason being that the more highly saturated the solution, the better the formation of the crystal and the larger the end product. This can easily be done by heating your solvent to a very high temperature and stiring in copious amounts of whatever is going to make up your crystal. Lower the heat as it goes and you should idealy end up with a very viscous solution, not so much of a liquid but more to the kind of stuff you get when you mix a bit of cornstarch with water. Thereafter dump everything in a beaker or bowl and suspend a thin wax thread in the solution itself. Cover up the bowl and leave to set for a few days. If you have done it correctly you should see a very nice, large crystal forming. Just a note though, don't let the thread touch the bottom of the bowl or even any thing other than the solution, or your crystal will be lopsided

Drink it ice cold with a little lemon juice in it.  Lemon juice is strong flavored, so you only need a little or it will taste sour, and that isn't good, so start with a teaspoon for 12 oz. of water, then adjust to taste.  If that doesn't work for you, add 1 packet artificial sweetener to your 12 oz glass with the juice.  Instant crystal lite!

blackpowder or gunpowder exploding makes the cracle sound. they just put it in smaller sections so it wont be as loud

disintegration, dispersion, interruption\n\nAny of these will work....

actually there is, but not perfect, it makes the vocal sounds softer...\n\nRealtek's Sound Effect\n\nyou can still hear some vocals but not so loud

I don't know if they use it yet, but there is a laser process that actually explodes the stones into smaller pieces so that they can pass. It sounds like you need surgery before you have a bigger problem.

When the sound wave reaches a very high octave....you can call it microwave.\n\nMicrowaves is used in the hospital to treat kidney stones. It breaks the stones.\n\nAbout weapons? Theres already such weapon..it is installed in a modern passenger ships for prevention against pirate attacks.\n\nWhen the cells are hit by soundwaves??? or microwaves??? it will not be disentigrated but causes some type of damage.

Well is there Kimberlite in the mine? Is it ultramafic rocks formed at phenominal heat and pressure? No? Then you aren't going to find a diamond in that mine if you would have in the first place. There's a reason they're rare.\n\nAnd beeswax? Nothing. That's not going to help you unless you want to use it to stop up your ears to drown out the machinery noise. Actually that's a good plan. You don't want to loose your hearing.

Probably ultrasonic....
