- Moving heavy stones is child's play if you have the right technique. Here's a video of my 4 Year old son lifting a 250Kg stone onto the top of a wall we're building. With this 5m lever, I've lifted a 420Kg stone off the floor and swung it through one metre or so each time with relative ease. You just need a long enough lever, strong chains, very stout fulcrum and a few buckets of gravel as counterweights. Ok, if you prefer, you could just hire a digger or crane to do the job in a fraction of the time :-)
Teaching your children to work is the best gift a parent can give! Love.
TH-cam has helped me so many times when it comes to fixing or doing things. It’s heartening to know someone else had success, and was kind enough to share what they learned 😊
Thanks for inspiring a child. I would gladly be that child. Child's brain is developing during this time and inspiration is important.
Teaching a kid to move a block in a creative way was a fun video to watch, thank you for the upload.
Thats so sweet how you involved the young fella in how large stones are moved, maybe this little guy could explain to those crack pots on ancient aliens that humans can lift big stones without the help of ET.
they had chains back then?
@@Adrian-vd8rm no, thei did not. You debunked the science. I mean ropes be sufficient enough, but we need chains.
There are many medieval illustrations (drawings and paintings) that show masons lifting stones using using wooden booms equipped with ropes or cables and windlasses. The windlasses in the pictures are turned by people, but they could also have been turned by horses or oxen. One illustration shows a large treadwheel windlass with a boy walking inside it, like a hamster in an exercise wheel. In some pictures the booms are shown at some distance from the place where the stones are being set. My grandfather used a boom with a pulley to load logs on a wagon -- mules provided the power.
a great way to expose the kid first-hand on what is mostly discussed in theory and paper, very tactful and contagiously inquisitive in the approach! a momentous undertaking in piquing his interest and making him love the power of physics! i salute you good sir!
Very well said sir! :)
I taught my two boys, that the word physics literally means how something works or how to do things.. I was dumb at school and the word scared me from it as a subject choice ,,
Thank you! This is the only video that shows how to get rocks UPhill without heavy equipment etc.
thats the right way to teach children, you are a good father
This video makes me think of influencing children for effort, dedication, and work toward a productive outcome. These are things that this generation of young people does not know.
Let's hope he learns proper grammar and hires out the rest
Hi All thanks for the comments. Safety - I tried to anticipate things that could go wrong, and some of them did before I lifted this last stone into place. I didn't expect my fulcrum to fall over though because it was well 'solid as a rock!' I always had one eye on my son to protect him.
First let me say I gave this video an enthusiastic "thumbs up," for reasons on many levels (getting it done, demonstrating the concept itself, teaching your son ... that last part is especially cool). Second, I would be the last person to "cast the first stone," as it were, at someone else for unexpected outcomes!
But with that context now established, I think you clearly understand the physics of this situation enough to see this snafu actually could have been anticipated? The wood base of the fulcrum is clearly not sitting entirely on the cement slab, some of it is extending over the edge (why, iI'm curious?), and once you started rotating the lever clockwise on the base, the center of gravity began shifting into the video-right direction, until it was no longer over the slab. At that point, the only thing that allowed you to keep it from falling over without continuing to apply a counteracting clockwise force on your end of the lever was having that other rock below to support it.
But again, very cool video, thanks for uploading!
No worries. You kept a sharp eye. This is a in a billion opportunity for such a small one in our age. Definitely worth the risk.
Keep children away
Respect to you for showing how you put your son in danger.
It was a moment of great shame for you but an invaluable lesson for your viewers.
Thank you for your courage to share your terrible mistake.
So easy, even a child can...whoops, watch out...get out of the way!!!

Chan Lyle Thank you very much for your kind comments!
Thanks for posting a near accident video. It makes us better engineers. From this experience, I recommend a three post tripod structure at the pivot point. I estimate three 2x4 and some ropes should be fine.
You have discovered the Secret od Pyramids building. You are a Genius!!!!
у меня бабушка никак не могла поверить как древние люди строили пирамиды и прочие сооружения из камня, не веря что банальным рычагом и рабской силой, можно поднять огромные веса, видео её переубедило хоть и не совсем.
Holy smokes I was worried something would slip. Thank goodness it was caught and corrected
"Give me a lever, a fulcrum and a place to stand, and I'll move the Earth"......
in the meantime, tractors and stuff
My Dad often quoted Archimedes
@@rumfordc in the meantime, other comments are helpful ^^
That's so cool he spends time with his family doing fun things like that
This is such a magnificent demonstration. It fills me with joy the shaduf still has its legs.
Fantastic. I’ve had so many heavy lift challenges around the yard. I need to work smarter not harder.
And that my friends is the perfect example of leverage.
Learning if fun
Teaching is priceless
A+
cute little boy
Lever, fulcrum, mechanical advantage, force, mass, physics 101
The idea was correct but base foot print is too small if anything it needs to be a few feet short of the beams end to avoid tipping but props too you
I have trouble believing you did this without aliens.
Haha I'm not prepared to divulge any extraterrestrial help I may or may not have benefitted from.
How did you get the pinched chain out?
SURE! but where would they get wood in the stone age?
Thats how Egyptians did it 100%.
Cranes simular to this mounted in niches every 30 feet or so all the way up the sides of the pyramid. With 4 sides of the pyramid working at the same time, a chain of many blocks was constantly being lifted up at a time. Counter weight cranes and a small crew of 25 people could work night and day doing this EASILY.
When I first started, I had chain and carabiners with a breaking strain of 600 kg, but they bent like plastic so I used 2000kg breaking strain in the end
Dang! I think that kid is stronger than me. I better get back to the gym and start working out.
Here we see, big alien and lil Alien moving heavy stones with Alien technology
Might use this method to move a heavy marble statue.
I love his little yellow wellingtons!
I like your way best because you not only lift the stone, you can move it to one side or the other. Thanks
Actual quote is " provide a fulcum, a place to stand and a long enough lever and I might get my wife's ass off the couch"
He could improve his operation by having a large circular barrel, maybe 7 feet diameter by 7 feet tall. Fill it with water, have a circular float in the water, have the beam attached to the float. The barrel or basin could be a longer trough instead of circular, so he could easily move the stone on the axis of the trough as well. He could lift very heavy stones if he strengthened the lever arm by having a mast with cables going down to the lever, like a suspension bridge. He could have another way of getting some vertical lift by adding water to the basin . When positioned just right he could lower the stone be letting water out of the basin
The idea was to get it done before the end of the century.
Cool. Let's go with a 5thousand ton Stone. Enjoy getting it up around 200 feet in the air. Great job.
True, if you only have to move them a short distance. But if you want to move them any distance you would have to unload the ballast, reposition the fulcrum and reload the ballast. And in your demonstration you almost had a significant failure.
Thanks for the comment Adam. 4 times the size? That's quite something! And yes, you need a lot of space. I need to move another stone soon where I don't have this space available. I'm still thinking about it.
This is a cool demonstration for moving stones a short distance on the ground. How did they move 20-ton blocks 1000's of feet and get them 400 feet in the air? You almost catapulted a child btw!
All my research into tripods and hoists...I forgot about a lever on a pivot point. Silly me :) Nice tool.
Impressive wall. I noticed in the comments that others would like to use your methid but have less swinging room. A smaller available area for the lever means you need a stronger but shorter arm with a heavier counterbalance. The weight on the pivot point is higher but the force required to move the weight is still the difference between the counterweight and the load.
Good luck.
PS. Increase the foot print of the pivot with some diagonal bracing to a larger x frame of beams. The base should be minimum the same width as the pivot is high. Since the force is down on the pivot the bracing can be lighter than the pivot post.
Block and tackle.
I wonder if I can build something like this using a very large beam nearby, float it down river, and spend a month slowly transporting a river rock that is the very long, wide, and a unknown amount of deep to my town for a future bathtub project.Hmm. Maybe I can carve out the inside of the stone first before I transport it to make the weight less.
Jesus! That kid was almost hurt!! Wow.
How do you tie the rope under the stone?
you got lucky !!! Gravity is a strong force !!! thanks for posting
I’m trying to rig something up so I can go pick up rocks myself and not bug my husband or friends to help. I have a few billion questions. In this example, is the lever attached to the fulcrum? And if so, how? For what I’m doing it needs to pivot up and down, and swing side to side. If you used a heavy duty sawhorse as a fulcrum, would it matter how long the spanning wood would be? In other words, how close the two sets of legs were to the center? If you used a piece of lumber as shown in this video, would a u rod with a rod through the width of the wood lever change how much it could lift? If you used a metal rod as a lever, could you use an eye bolt threaded through the wood of the sawhorses? Would it have to be oval shaped to allow the lever to raise to a good height? What about a ball bearing to allow the lever to pivot side to side? So many questions!
The magic of working smart.
I need to employ this method to move a few large rocks, what I don't know, is for a 400lb rock, and I am 200 lbs, how long of a lever do I need? I do understand to double my force, the pivot/fulcrum has to be half way between the center of the lever and the rock. Another issue I have is how to use a wood lever to pivot on top of a wood column as I need to swing 180 degrees, then reset to keep moving the rock till I reach the final destination. I need a smooth pivot system.... any ideas?
dviii hi, just remember that for the lever to balance, force x distance at one side of the fulcrum equals force x distance at the other side. My lever is 5 metres long and the fulcrum is about 1 metre from the heavy rock. this gives a mechanical advantage of 4:1. so to balance your 400lb rock you'd need 100lb on the other end.
dviii As for the pivot, my lever was simply resting atop the fulcrum. I suppose you could fashion a pivot but I didn't find it necessary. Make sure your fulcrum base is wide enough so that it doesn't topple over and remember stay safe! Keep your children, pets etc out of the way. I mean no-one would be daft enough to put their children at risk, would they? Good luck!
Buen metodo , cuantos kg pesa esa piedra??😮😮😮
This is the most likely method for how the pyramids were built, they are easy to construct tools. the Egyptians were already using similar devices to gather water,not a far stretch to build a few hundred larger levers to lift blocks. Some times the most simple answer is the best.
Thanks for the comment Sneelock, and good work with the saws!
And they’re still standing :)
If I would try to do this with my grandchildren, my wife definitely wouldn't film it 😅
@Will G so good ! Thanks you, I like so much your ideas !
Do not hang the bucket. Place on top of the beam for more play.
LUCKILY NO GRANDKIDS WERE HARMED IN THE MAKING OF THIS VIDEO. L.O.L.
Fursday - I used D shackles and carabiners to hold the chain in place. That was a problem though because the chain links were very narrow and I couldn't get two sections of chain into one shackle, make sure they fit in the store before you buy! It's quite easy to lever one side of the stone up with a block of wood and a long pole to remove the chain. You can repeat this at each side if you need to.
holy cow, that things got to be at least 80 lbs!
hi thanks for watching. what do you think weighs 80 lbs?
+verminr that's about a 300 lb stone easy. lol 80 lbs?
+verminr I meant that reply for the other guy moviemaker
+keano hihm Yes, balance is a wonderful thing. just 1 small pebble extra in the bucket lifted the stone about a quarter inch
prob 400-500lbs
How you tie the chain to the rock and ,,,How do you get the chain out from under the rock if it's so heavy ?
fursday because it’s nowhere near as heavy as he’s saying. 2 men could probably lift that
You use a leaver.
I admire your ingenuity and creative solution to a massive challenge. As the most poignant learning moment in this video has been widely dismissed, what do you believe the outcome would have been had your pivot point kicked out completely? At 45 seconds into the clip your entire world almost changed.
Thanks for your comment. I believe the beam would have fallen clumsily and come to rest on the bucket of gravel at my end and on the large stone at the opposite end. I don't think it would have been very dramatic. Do you see it differently?
And that,, is how the pyramids were built ladies and gents. One tier at a time.
How do you get chain out. Simple. Wood under rock. How do you get wood out. Simple Use wood. ...Typically movers would use straps on both sides for faster work.
+David, use a big pry bar.
But that’s not how they did it.
They utilized planet earths magnetic electro grid. (Yes that order) better said as acoustic levitations. They used sound to levitate rocks otherwise impossible to lift and floated them globally. This is what the Stonehenges were.
Cool idea, show Michael Tellenger, he will tell you to use your flute and use sound, glad you did not have the accident that look positively horrific and likely
Wow - great idea, but that looks really unsafe! Is there not a way to affix that pivot point down?
Skipping ahead to 2022 post pandemic times that top timber would cost about $1500
Well executed! Don't you listen to all these 'old ladies' on here, nagging about things they don't understand.
Thank you .....and you tube is awesome I got the same project to do
Step 1: Lift boulder with floor jack and attach chain. Step 2: Place huge wooden beam through chain on boulder and balance on middle pedestal. Step 3: Attach two heavy buckets of gravel on opposite end of wood beam for counter weights. Step 4: Find a 4 year old to assist you pushing the wood beam until it topples over. Not sure what I learned from all this but I loved the video!
use one tripod and pulleys, then another tripod and the weight easily moves from one tripod to the other, that is the right way. Rise the weight in one tripod and attach to second tripod and then detach slowly from first tripod and the weight goes to second
Nice idea Will G. I like it!
0:44 i was about to say what's stopping this from tipping over ...asked & answered..lol
jonathan joestar after being healed by zeppeli:
more evidence of alien technology bahahahahaaaaa ;)
This just proves that Children didn't build the Pyramids.
Now we know how The pyramids were built thanks.
Ahhh, but did the Egyptians have steel chain?
Obviously he should set the block on ice cubes to get the chain out.
el señor lo hizo bien, buen video
Good science. Careful though
wally wallington......
Hi Verminr! I need to lift some stones in my yard - I was curious if you drew plans for your lever and if I could see them? That way I can adapt them to what I need to do? Thanks!
Awesome 👌 thanks
Hi nex0s nothing as sophisticated as 'plans', I basically scaled everything up after my first levers and chains snapped under the weight! What I arrived at was a 5 metre long roof beam and chain with a breaking strain of 2000 Kg. I made the fulcrum from sections of fence post glued and screwed together. How heavy are your stones?
That's excellent (even with the near accidental drop), but I wish he had shown how he got the chains under the stone.
Steve Raymond Thanks. That's the easy bit. Just lever under one side with a long pole then kick the chain under. (Unless you've got a helper to slide the chains under)
And they say we have no idea how the ancients moved all those heavy stones
How thick is the wooden beam? Thicking of doing something similar
Hi Alex It's 14cm by 12cm and 5 metres long. It weighs 50kg and I collected it from the woodyard on my mountain bike :-)
verminr thanks for replying! How did the wood hold up? My rocks are about 500kg, maybe up to 750. I’ll probably see if I can get it a shade thicker. Any improvements you would make to this in retrospect?
@@YaboiMSG The wood flexed a bit as wood does, but never felt like it was going to break. Read through all the comments here there have been some good suggestions. I would make the fulcrum much more stable next time. I was lucky that I had plenty of room to swing the lever round otherwise a different approach required. Good luck and let us know how you get on!
verminr thanks! Yh I think I’ll put some supports on the fulcrum to stop it tipping. How easy was it to rotate? Not sure how to rig it up in a way which is easy to rotate
@@YaboiMSG It was very easy to rotate and not fastened to the fulcrum just resting on top. I guess you could connect it if you're worried about it sliding off
That thing almost turned into a kid catapult
muy bien ahora ...como le hicieron para llevar las grandes piedras en machu pichu peru ..entiendo que si se puede levantar una piedra como ese tamaño o mas grande pero TRANSPORTARLA es otro asunto...te encuentra en un lugar fijo
This is till using Steel chains. Which has never been found anywhere in Egypt. But good try.
An thus we learn about momentum.
great idea Vinit!
Thanks
Fun times getting back the chain
The old boy means well, I am sure, but the child should be at a safe distance...
Ok multiply that weight by a million. That would take a real long pole
Nice
Looks like someone is gonna get hurt...
That's how the Egyptians got their start
