Earlier work from Experimentarium. Show what a top-athlete’s heart can do compared to an ordinary person … You have a few hours to develop and produce a visual demonstration. The Experimentarium was to help TV2 Sport demonstrate the capability of a top rower. We quickly got the idea to use 2 small fountain pumps to show the difference in the flow capacity. Made a couple of calculations, found appropriate pumps and other items from the storage that could be used for the installation. Constructed a box for controlling the pumps, made a test of the system, and got ready for shooting. You can see the result here in the video in the link 🙂 It was a little messy, but the visual effect worked.
