Step 2 Making the mysterious liquid

I filled my bottle with copper sulfate solution I made from CuSO4 x 5 H2O salt. You can buy the salt at your local department store. ;)

There is a lot of different colours salts. Ammonium cobalt sulfate is shiny red, potassium dichromate deep red, ammonium dihydrogen phosphate is green. You can find best colours by experimenting.

Well you can paint your liquid, but playing with chemicals is more dangerous and fun. 
BY CAREFUL COPPER SULFATE IS HARMFUL!
I added some small shiny tinsel in a solution. They make my liquid more freezing.

If you want a mad scientist effect, light the liquid with a UV led. If you want a UV (fluorescent) dye, the dye "fluorescein" gives an eerie green-yellow glow. Or take fluorescent poster paint and add it by the drop to water until you get the color you want. You can also use vegetable oil with some oil-based dyes. Experiment!
