without trip to the store you can do sugar, salt, and possibly alum if you've got it.

unless you have sulfuric acid and some copper metal, you can do copper sulfate crystals then which are awesome (very blue)

AMAZING CRYSTALS, MAN

I think this is what your fishing for...

You'll need about a half a dozen pennies 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,
the brand doesn't matter. Pour it in until the jar is 2/3 of the way full, or as tall as
you want the crystals to grow.

The last ingredient is laundry bleach, fill the rest of the jar. Be sure not to spill any
on your clothes.

Now drop the pennies into 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 form after about
30 seconds of blowing.

The pink and purple some from the production of copper-calciphate using the CO2 in your own
breath. Blowing until you're dizzy actually increases the CO2 in your breath, giving the
crystals more vibrant colors.

Enjoy your crystals!!!

I tried that copypasta recipe before and it didn't do anything but make a little bit of blue buildup on the pennies. Nothing more came of it. I didn't like blowing on the pennies because of the bleach smell so I tied a shirt sleeve over my nose.

Got any recipes that don't involve blowing through a straw/hyperventilation?

I saw one that was made with lemon juice but I don't have the recipe

bleach + ammonia = chlorine gas.

Oh yeah, and why does it have to be in a jar? I'd rather do it in a shallow pan so that blowing on the pennies doesn't cause the solution to bubble so much.
