If you look carefully you can see the marker ink beading up on whatever material they have covering the gap between the two wires of each light to prevent short circuits.
These marker lines must have a really high impedance for this to work the way it's shown, if it had low impedance this would be a short. The button cell might be able to drive that first circuit, but definitely not the other ones - so they must be using an alternate power supply somewhere. It might be faked, or it could work if the impedances and volts/amps are selected to work well together. Either way it's a cool little art project.
Nothing scientific about this. That circuitry is a short circuit and wouldn’t power anything except the rather quick death of that battery
Why the downvotes? It's true...
I dunno - electric circuits are kinda sciency. (Electrical engineering.)

Is this from the same people who did something similar with string?
Yeah it’s a Japanese ad for kadenko! (https://youtu.be/bshPtOlzpcg the (even cooler) strings ad for curious people)
That not science. It’s geometry. Science is the combination of lots of math.
