Not sure what they are doing here, my suspicion is the led's just have an interrupted ground, and the water bridges the gap.

I wonder if the water is salted (or something) to make it a bit more conductive - those are pretty bright LEDs to have their power running through plain water.

This is awesome though.

I suspect unless one was using distilled water there will be enough contaminants to work as a good conductor. its only got to bridge a fraction of a millimeter around a very squigly pad.

i love how low-tech it is, but yet has a very high tech look.
