I am happy to announce the release of the first part of Geometric Objects. In this part I conduct two tests with two arrays of Pyramids. 1. the cheops style Pyramid and 2. the Russian style pyramid. The tests are crystal formation and ph change of demineralised water over a period of 5 days. You will find a new menu point under movies for that. Or click on the direct link here. The content is for Gold Members only.
