We have seen several pictures of Santa. Santa high up and low down. How does it work?

The system was designed, implemented and perfected in long hours by Thomas M and Peter P. A patent is pending. Wouldn't it not be for the pump, it would be a Perpetum Mobile.

Santa's ladder hangs on a rope, and a 20 lt container hangs on the other side of the rope.

Water (with cooling fluid, as it is winter) is pumped from a large bucket into the container.
