Introduction: Blue Heart

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 (https://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!

Step 1: Get Stuff

Parts:
1 - Bottle with cap
3 - Blue leds
1 - 9v Battery
1 - 9v Battery clap
1 - ON/OFF Switch
Some wires
Enought liquid to fill bottle

Tools:
Knife
Hot glue gun
Soldering iron
Dremel or drill

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.

Step 3: Make the Cap

Design is very simple just:

1. Prepare your bottle cap.
2. Drill hole and place 3 leds in it.
3. Glue leds with hot glue.
4. Solder your leds and switch.
5. Connect leds with a battery.
There is schematics.

You can add some crystals like i did. ;)

Step 4: Complete Everything

Just make some nice facing. I used copper wire for making a heart and added Myliu Tave "I love you" in my language. :)

Step 5: Overview

Thats it! I made it! :D Small shiny blue night lamp with a heart. :)
Only two hours from idea to finished thing! :) Sure you can make blue bawls concept lamp with light sensitive switch or something much better.
But that is enough for me. :)

However my girlfriend was very happy. ;)

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

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! =)

author
Zujus (author)Jimbo2422007-09-19

Thanks! I just glued them :)

author
Jimbo242 (author)Zujus2007-09-19

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! :)
