I will make a few experiments with pyramids made of glass, plastic, copper and several layers of wool and copper (like an orgone chamber) and then report the results.
BTW I have an egg in the fridge, it's more than TEN years there, no signs of decomposition, only de-hydration. Coming days I will open it step by step, make pictures and write down what had happened.
The shape of a perfect egg is also an example of Holy Geometry, for me.
Nature is our best teacher, thinking of BIONICS.
