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!
