The Egyptian pyramids are huge structures which are almost 4600 years old. The Pyramid of Cheops consists of 2300000 stones. Each of the stones weighs 2.5 tonnes.
According to the usual explanation large blocks of stone were cut in the mountains and then transported with the help of the most primitive equipment. So about 100 thousand people had to take part in the construction.
But the modern experiments show that the stones of pyramids were made synthetically. The Egyptians produced some special solution. Later they mixed it with one of the minerals. It took them several hours to transform this mixture into very hard rock. This rock was produced just on the construction sites and so there was no need of transporting heavy stones.
