The problem with most light fittings is that they're only about style: they're the preserve of hipsters and interior designers. If you want something a little more geeky, why not make your own test tube chandelier?
This was actually dreamt up by Polish designer Pani Jurek and is called the Maria S.C. chandelier. In fact, it's named after Maria Sklodowska-Curie, the the deservedly world-famous female scientist. But as they suggest over at MAKE, it would be fairly easy to put together yourself. You just need a ring or two of wood, an appropriately sized drill bit and a bunch of test tubes. Every home can cope with more test tubes, right? [Pani Jurek via Design Milk, MAKE]
