The effect of a model pyramid of Egyptian type on plants, aqueous solutions, and solids was studied. It was found that a presowing holding of dry barley seeds in the pyramid stimulated the growth of this plant. On the contrary, "pyramid" water, when used in sowing, suppressed the early growth of plants. The pH of the water held in a pyramid changed compared to the norm. A threefold increase in the rate of decomposition of hydrogen peroxide was observed when an aqueous H2O2 solution was held in a pyramid. It was also found that the masses of both biological objects (seeds) and inorganic solids (quartz) changed in the intrapyramidal space.
