Hope this is the right place, to place this 
i made this little lamp recently, it's easy to make and fun to play with
Materials needed
This has to be done in order for lamp to work properly. The neck of the bottle must be shortened about 1/8 of an inch
I sanded the body of the bottle for "milky" light but not necessary
Some kind of stronger thread (i used waxed leather sawing thread) must go under that wire, when done this way thread is secured and can't fall out
All that goes in to the bottle. LED lights up at first, but when the "switch" pass the neck of the bottle it goes out
It looks like this
When pulled on the thread
Cap can be screwed on with the thread crumpled inside, in on and off "mode" and it's water friendly
Here is how it works

It's not the brightest boy of the bunch, but can illuminate some area, and used for reading in a pinch
Thanks for watching
