This is small gift I made for my girlfriend for Valentine's day. :) Blue is her favorite color. So I decided to make something that is really blue.

First idea was to make copper sulphate crystals (http://www.instructables.com/id/Grow-Crystals/) So i was started making crystals but i failed. :( After two days i only had some small crystals and 2oz of that strange blue liquid you see in picture left...

There was only 2 hours before midnight left, and I decided tomorrow i must gift something to my girlfriend! Then I started thinking and idea shot straight to my head. I grabbed my instructables MagLite and just lighted to bottle with that solution...

This time my failure became succes!

DWReadsays: You can make a pretty greenish blue solution by putting copper in AMMONIA. Pennies may work, depending on when they were minted, but I would just go to a hardware store and buy a small copper connector from the plumbing department.

Just one little drawback. AMMONIA smells REALLY bad. :D

well done dude!

Ammonium dihydrogen phosphate does not make green, in fact, in solution it's colorless. Did you mean something else, because i'm trying for green. I went looking for a alternative and i found copper chlorate, but thats not too easy to get your hands on. I might end up just making it....

you couldve suspended a smaller heart in the liquid so it has a morenoticeable look iin the dark

People, stop making fun of his English! Just appreciate what he has done. He obviously knows English isn't his forte and yet has shared this with all of us. We can't speak his language even half as well as how he speaks English. Some of you are so narrow minded! Grow Up!

This is well cool, im gonna make this my self, but how do you grow the crystals on the lid? i searched for an instrucables, but all that told me was how to grow them from a botton and wire :/ Maybe you could make another instrucable for this bit. Thank you if you do! =)
Zujus (author) in reply to Jimbo242Sep 19, 2007. 9:33 AM
Thanks! I just glued them :)
Jimbo242 in reply to ZujusSep 19, 2007. 10:53 AM
yeah but how did you make them in the first place, did you just make them on some string and then just filed one side so it was flat enough to be glued to the lid?

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!

Thats cool! I will try it ;) thanks! :)
