Place a lump of coal in bowl and sprinkle 1 Tbsp. salt over the coal. Carefully pour 2 Tbsp. water over salt. In the same manner, pour 2 Tbsp. of laundry bluing. Then add 2 or 3 drops of mercurochrome. Repeat with food coloring. After several days, you should have a colorful mosslike growth. If not, add a few more drops of water. This is something small children really enjoy!

these were called depression roses, back in the old days, you can use a regular rock too instead of coal but it doesn't look nearly as good

What is mercurochrome and where can I get it?
Ask the pharmacist or chemist. It is an antiseptic.

Is that coal from the BBQ? and do you know where to get bluing? Thanks for any feed back.
The bluing is usually found in older style dime stores or pharmacies. I also found it in WalMart.
