[BadWolf's] girlfriend wanted him to build her a lamp for Christmas and he didn’t disappoint. What he came up with is a water-filled color changing lamp with bubbles for added interest. See for yourself in the clip after the jump.

The color changing properties are easily taken care of by some waterproof RGB LED strips. [BadWolf] went the Arduino route for this project but any microcontroller will be able to fill the role of color cycling. The enclosure is all hand-made from acrylic sheets. He grabbed some chemical welding liquid from the hardware store and applied it to the acrylic with a syringe. That’s easy enough when attaching the edges to one side of the enclosure. But it gets much tougher when it’s time to seal up the other side. He recorded a video of this which shows the syringe taped to a rod so he can get it down in there, pushing the plunger with a second extension device.

Bubbles are supplied by a small aquarium pump. We’re wondering if this will need frequent cleaning or if you can get some pool chemicals to keeps it nice and clear (or just a teaspoon of bleach)?
