Researchers from the FOM Foundation and the University of Amsterdam have figured out how the ancient Egyptians transported huge stones across desert sands to build the famed pyramids. Through experiments and simulated desert conditions, scientists determined that the secret of moving heavy stones across the porous surface of the desert lies in the dampness of sand.

Egyptologists have been able to explain how the ancient Egyptians transported heavy cargo from the quarries to building sites using barges, but the question of moving the 2.5 ton stones across the desert has, until recently, plagued scientists and mechanical engineers alike. Researchers at the University of Amsterdam conducted several experiments and concluded that the ancient Egyptians must have dampened the sand for the sleds-large slabs with upturned edges–to slide over it without it digging into the sand ahead.

The research revealed that sand with just the right amount of moisture can double its stiffness. Thanks to microdroplets of water that bind grains of sand together through capillary action, friction and the force required to drag the sled are cut in half. An ancient artwork found within the tomb of the Middle Kingdom nomarch Djehutihotep confirms the new scientific findings. The image includes a representation of a slave pouring liquid into the sand in front of the sled.

    My family is from North Africa.They claim that the liquid used wasn’t water,but clarified butter. The sand is so hot it never hardens.

    If the 50 ton stones took 1 liter of water to move 1 feet (even though it sounds ridiculous) and all the stones were a mere 1 km away (even more ridiculous) then the water it would take to make an entire pyramid would be enough to fill 787 Olympic sized swimming pools. Yes, I have done the math. I cannot begin to express how stupid it sounds. 3-4000 years ago, people wasting that much water just to shift the stones.

    Not buying it for a minute. And that “painting” confirming it? I’d bet that painting isn’t even old enough to vote, lol.

    guess it depends on when you believe when the pyramids were built it wasn’t desert around 12,000 years ago but the “Egyptologists” don’t want you to believe they were built that long ago otherwise it makes their work irrelevant, so how did they get the stones so tight then ?

    @Doc. Brilliant. They could even build a frame around the stone- right in the quarry, mount massive wheels-sets to them. Once the wheels were on, they could simply “cut the stone free” alleviating any need for cranes or hoists. they could then easily roll these across the desert. They probably had master craftsmen on hand for repairs. When completed, they clear long ramps out and pull. As others here have mentioned, the water is likely there to water the ropes. When at Giza, they could use sand as a temporary ramping surface that is built up between trips by another crew. They could roll these pseudo carts within millimeters of where they need to be. Lastly, they wash the sand from beneath the wheels, settling the stone in place. Well, that’s my theory of one way they may have done it.

    Considering the watering, and constant heavy tamping, went on for so long, you’d think there has to be some sort of hardened path below the current surface. They must have just hammered a path. No?

    I have to agree with the theory that it was the Anunnaki. Just ask the Zetas.

  8. Colin Taylor January 5, 2015 at 3:01 pm

    so it was nothing to do with the giants that lived on the earth that they have found the bones of,or the aliens that are returning..god i was so blind to see that it was the dampness of the sand lol

  9. Colin Proctor January 4, 2015 at 5:14 pm

    I think it has more to do we with frequency and vibration…wet sand?, I don\\\’t think so.

    “Researchers at the University of Amsterdam . . . concluded that the ancient Egyptians must have dampened the sand for the sleds — large slabs with upturned edges — to slide over it without it digging into the sand ahead.”

    Killer funny. Thanks, “scientists.”

  11. Doc. November 20, 2014 at 1:38 am

    Build a wheel fitted to each end of the stone and roll it.

  12. Matthew Petti November 19, 2014 at 8:48 am

    This is such a crock! I still don’t think that people quite understand the magnitude of such a task. As long as “experts” keep telling us how it was done, we will find many believers who don’t know any better.

    Chris Dunn has proven that, utilizing today’s technologies of quarrying the stones and using modern-day delivery methods would have taken 27 years! The Great Pyramid was purportedly built during the reign of Cheops, which was just shy of 23 years.

    Most people are unaware of the optician’s tolerance in the accuracy of its construction. For a brief overview of these facts, go here: http://matthewpetti.com/the-greatest-lie-on-earth/

    You mean it wasn\\\’t aliens?

  14. Arthur Applegate May 10, 2014 at 2:51 pm

    Clearly some of you did not live by the ocean. The wet sand down by the waterline is about as hard as concreat.

  15. John Rambo May 6, 2014 at 12:50 pm

    Let’s remember that this hypothesis is just that, speculative. Avoiding phrasing which makes a theory sound absolute might be beneficial in the future.

    It is truly impressive how ancient civilizations discovered building techniques which were far superior to what we know from our (even recent) history. Pyramids in Egypt are such a powerful memento of the rise and decline of great empires, something that is still important for the rulers of today. Furthermore, one of the reasons why Egyptian empire declined, was the climate change that turned big parts of their territory into a desert.

    and how exactly did they manage to cross the nile river??? i hope they didn’t ‘sand’ the river….

  18. bdblondeau May 3, 2014 at 1:34 pm

    It was to strangthen the ropes, not the sand. Take a dry shirt and pull something, do the same with a wet shirt and you will be amazed at the strength differences

  19. pmanke May 2, 2014 at 11:22 am

    I wonder about the possibility of having used some type of bitumen or crude oil from seeps or shallow well pools that may have been present long before drilling oil wells came along, like the tar pits in CA.. I agree with previous comment that without some additive, the ability of sand to hold water at elevation is very limited. There’s also the possibility of having adding plant mater for lubrication, but the old illustration shows a black line comming from a jar at the front of the sledge; asphalt?..

  20. Robert Sultani May 2, 2014 at 10:00 am

    Interesting and that was the “theory before” but still doesn’t hold water …think about the fact that the blocks were so accurate put together that you cannot even put one piece of paper together between them.Then think about how many km long the ramp would have to be to sled the blocks to the top and the higher the ram the less firmness the sand will be. It is theoretically impossible to get 100% compaction on sand especially when 2.5 rock is pressing down on it.

  21. webartogo May 1, 2014 at 10:24 pm

    Well a fine idea on the surface, but where and how did they have enough water to go the distance?
    And they still had to lift up the blocks and statues when they got them to the building sites!

  22. abcd May 1, 2014 at 9:25 pm

    And it’s all already explained on the drawing? How could it take them until now to translate that drawing?

  23. RelayerM31 May 1, 2014 at 8:53 pm

    The old wet-sand-under-the-sled trick. I KNEW it.

  24. richpix May 1, 2014 at 10:34 am

    And then there\’s the 60 men pulling the sledge. That works out to about 83 pounds per person.

    They could also have used oil as a lubricant under the sledge
