If you have not seen the Household Hacker on YouTube yet, you need to for stuff like this awesome cloud light you can be taught to make.
You need some cotton, a few empty bottles, some Christmas lights and some glue. Seriously. If you happen to have all those lying around and have under four minutes to watch this video, you could have your own awesome cloud light by the end of the day.
It really is THAT easy, and it really looks THAT awesome.
