Perpetual Motion Machine: The real-life version of M.C.Escher's Waterfall

Step 9 5.3 The third floor of the left tower

It can be seen from Google Sketch Up, only the third level of the left tower is at the highest level for the whole ‘waterfall’ model. This design is to facilitate the falling down of the water and therefore to make a great impaction against the waterwheel.

Initial results were worked out. However, we are not supposed to put on those texture at this time.

The figure presents the discharging point of the Waterfall in the third level of the tower.


Two PVC pipes were used to set up the discharging point of the waterfall. The connection place was glued using hot sol gel. We must ensure that the PVC pipe in the right hand side should be blocked by the one in left hand side from observation. This is to avoid being seen through.

In order to get close to the original effect of the waterfall, a transparent plastic film has been placed in the discharging point of the waterfall. The water will then flow down along this film.
