A kinetic fountain can also work at night lit by 3 LEDs. The electric source is a battery recharged by a solar panel.

It runs every night from 20 to 23 H.





One way to keep the balls going is by catching them in an umbrella.

They will then roll back down into the jets.

However, the system is too complex: after a while all the balls get stuck in one pile somewhere slightly up the side, outside the jets.

Still, it's quite nice when it works.
