In order to investigate the secrets of water, Walter Schauberger built large clear funnels in order to observe the water as it drained through funnel forming interesting vortex patterns. A picture of one of Walter's orignal funnels is included above. He concluded that there was a predictable harmony to water's spiraling motion. This form of motion was made more pronounced by flowing through the natural shape of the hyperbolic funnel. You can now observe these wondrous effects yourself with this 3D printing file (available here only in .stl format). This is a 3D printing file of a 10 inch long hyperbolic funnel which has a inlet hole for a hose to be placed in (pictured above). When a hose is fed through the inlet tube, a vortex is created in the enclosure from the draining water. Walter found that this precisely calaculated funnel shape has an influence on the structure of the vortex and causes it to exhibit interesting spinal column shapes, which had never before been seen! You can observe this when the funnel is printed from a clear material. Once again, these spiral shapes that look like a spine are only observed in an hyperbolic funnel. The significance of this funnel shape can be seen throughout nature, in the inherent shape of the gravity field, the curve of a vortex of draining water, or even in the narrowing shape of a tree trunk. Walter and Viktor Schauberger, two pioneers in biomimicry, used this funnel to experiment with and better understand the nature of a fluid vortex. We must get our facts directly from observing nature as Viktor suggested. This is a tool to visualize what water does when it is spun in a natural shape.
For mounting, the funnel has two traingulated supports as shown which you would connect to supports. They each have a hole for a screw to mount with. This file is for research and artistic purposes only; non commercial.
