Maybe you have already seen the link on the right to AfriGadget, a great web site dedicated to showing how to solve "everyday problems with African ingenuity". I really suggest that you have a look at it! Today I came across another great idea, this time from South America: lights made from water bottles!


If you have questions about this great solution, check out the comments on Make. Well, and now that you're already here you should have a look at the websites that are on the right in the "On deed a day" section, it's worth it.
