ITT: We make really cool crystals, and post results! Okay, so this is easy, you should have all of the chemicals needed around the house! You'll need around 5-over 9000 pennies (or copper coin from your country) and a straw, put these aside. Get a clear jar, scoop 2 tablespoons of salt into it, and 1 tablespoon of baking soda. Now the first important ingredient should be in the bathroom cleaning supplies. Ammonia (any brand) Pour it in until the jar is 2/3 of the way full (as tall as you want the crystals to grow) The last ingredient is laundry bleach (careful not to spill on your clothes!) fill the rest of the jar. Now drop the pennies isnto the bottom, and quickly take the straw and blow bubbles onto the pennies to get the crystals going. You should begin to see stringy crystals from after about 30 seconds of blowing. That's it! The pink and purple some frm the production of copper-calciphate using the C02 in your own breath! (blowing until your dizzy actually increases the C02 in your breath, giving you better colors)
