For those of you with an overwhelming desire to build your own subatomic particle accelerator, look no further than this Instructable by Xellers, which shows you how to convert a wine bottle into a cathode ray tube (CRT). Of course, that’s not all you need: other ingredients include a two-stage vacuum pump, a neon sign transformer, a high voltage microwave oven diode, and a few other parts that can be found at your local hardware store. Xellers doesn’t recommend running the tube for more than 40 seconds at a time, so unfortunately you’ll have to use a different method to build that needlessly complex (albeit really cool) reading light you’ve been dreaming up.

The Cathode Ray Tube site, old electronic glassware…
