Maybe the ancient Egyptians used this method to build pyramids

After making a hypothesis about how Egyptians built pyramids, construction company boss Chris Massey and his son did demonstration experiments.

Maybe stone built pyramids is transported by water.

Chris Massey hypothesized: The ancient Egyptians released large blocks of rock floating in the water and the pressure of water raised the stone hundreds of meters high along the axis leading to the pyramid

He and his son did experiments with water tanks to see if the stones were floating and the water raised high.

The experiment was performed three times on different scales. The following video shows how Chris Massey did the experiment and how it worked.
