Instructions

Two wires will be used as GND and VCC to power up the LEDs.
I soldered an LED + 330 ohm resistor in each sphere and used superglue to seal the spheres.
Finally the GND in the rightmost sphere will be connected to a magnet (using copper-tape), and the VCC of the leftmost sphere will be connected to another magnet.
Add a coin cell battery between the two magnets.
