Summary:

According to the video, a new study suggests that ancient Egyptians may have used hydraulic force to build the step pyramid of Pharaoh Djoser. The pyramid is the oldest of the seven monumental pyramids in Egypt and was the largest structure at the time, with stones weighing more than 600 pounds. Researchers believe that a nearby structure may have functioned as a dam, and that water could have flowed into shafts inside the pyramid, raising a float that carried the stones like a water elevator. However, some experts are skeptical of this theory, as there is no evidence that the Egyptians had the technology to use water pressure in this way. More research is needed to determine if this theory is correct.
