Okay, check this out – if you're a huge nerd like me, you'll probably dig this project. Popular Science posted this DIY bubbling hanging lamp project, and it's pretty cool.
You see, what I usually do is find these articles and say to myself, "self, this projcet is really cool! I should totally build that!" The next thing you know, it's two weeks later and I forgot about it because I got too busy. That is why I post this stuff here – so somebody can make use of stuff I think is pretty awesome.
It's a ridiculously simple design – a vapor-proof/explosion proof enclosure, some mineral oil (and color), cable, a pump to generate bubbles, and a lamp. You can buy parts from McMaster Carr or Grainger and put this together yourself, right? Of course you can! That is, unless you forget about it.
