Step 1: The Gift
But the idea of packing it into a simple box with ribbon wasn't satisfying - 'couse we're engineers! :P
Step 2: LED It Out! ;)
Brilliant idea! Shine the inside of our can with LED. Hey, but that's not enough - let's make this gift sweeter! Let's find some sweets! Shiny sweets ofcourse!
And here we have a full gift-package kit...
Step 3: Let There Be Light!
We used a "flux" type LED - it has 4 legs. You need to bend them, so they would hold the batteries tight.
Step 4: Gift in the Hole!
Oh, and one more thing - because our gift has a lot of black string and it somehow dimms-down the light inside the can, we added a shiny aluminium "cup" from tealight to separate it from other shiny things inside.
Check out the result - nice, green shine :) Close it and give it :)
PS. It should work at least a couple of hours - depends on batteries.
