Why does the leaning tower of Pisa lean? | Sci Guide with Jheni Osman | Head Squeeze

[@BBCEarthScience]

Oops. 100kg and 14.5 tonnes do seem a bit light! We seem to be missing a few zeros, sorry about that. We meant, and should have, said “Not ideal for around 14,5000 tons of marble on top.” And “Around 100kg of soil was removed each day over the course of the year.” What a different building it would be if it was only 14.5 tonnes!

[@thoruszwolf4153]

100kg of soil is still only one or two wheelbarrow's full, I could do that in less than 5 minutes

[@miks8]

what number is "14,5000" exactly? is it 145 thousand or 14,5 thousand ?

[@HRHooChicken]

Surely someone should have realised that mistake... the cameraman, the cleaner?

[@gcajones]

A good episode. A common-sense fact check would have avoided the embarrassment. :(

[@amef15]

Wow. What a lame channel. They can't get their numbers correct, and the correction is also wrong. No quality control whatsoever. THUMBS DOWN!!

[@MrSquishedsquashed]

"Engineers claim the tower can now survive for another 3 centuries. Well we'll see about that." Why does this sound like she intends to bring down the tower?

[@ADEehrh]

😄😅😆

[@miltonjunior5173]

She didn’t mean that! R u illiterate ?

"Removed 100 kilograms of dirt in a year." what, did a single guy use a spoon with breaks every half hour?

[@Titanic-wo6bq]

probably

[@Mr333Lee]

Wow, a whole 100kg of dirt, wonder we're they put all that

[@nexxogen]

That's like 3 to 5 large bags of potting soil that you can buy in a store.

[@ivo3185]

I loved this video, apart from the measurement problems. I can't wait to see more of Jheni. Her accent is beautiful, her voice is really soothing and she explains things really well.

[@GetOutsideYourself]

She also has perfect teeth.

[@Neueregel]

Jonathan Stewart she seems drunk though

[@TheManwithafan]

Neueregel Your comment is drunk

[@Neueregel]

***** I never drink ethanol=poison

[@geoffphuketInPhuket]

Excuse me! Who wrote the script for this video? They removed 100Kg of soil over 1 year (2:48). Are you serious? I could do that under 5 minutes. And what's that about it weighing 14.5 tons? (0:20). A few blocks of marble would weigh that much alone!

[@dimosk7389]

14,5 tons??? 100kgs of soil??? they tied it to the ROOF of a nearby cathedral which probably is as old as the tower itself??? come on, i love this channel, but you have to check your numbers better

[@aarondozier141]

Soft soil, a river, and limited resources in the old ages, today since the structure is now historical, engineers are doing what they can to stabilize the tower. My speculation is there is still underground water flowing perhaps slowly, which is keeping the soil soft. Id say create a cylinder of cement as a damn around the tower add weights just enough to keep it leaning as it is. Hope to keep this comment positive.

[@Marblez3]

LOL. "Tie it to the nearby cathedral". Sounds like something out of a Chevy Chase movie where the whole roof of the cathedral will be ripped off.

[@TechLaboratories]

As foolish as it was to complete a tower that size that was already leaning, the building wouldn't be anywhere near as famous if it weren't on an angle. So... thank you?

[@Khloe_dancer_model]

exactly! it would be.. just a tower

[@jeffrydelarca2080]

TechLaboratories Kkkmk

[@CharleeLi]

thank you very much for making this video! my daughter had a project on the leaning tower of Pisa and this helped her a lot!

[@chronousnemesis]

A bus with full capacity weights about 14 tonne. And 100 kilogram of soil is nothing for a construction worker even for a day lol. Jheni is quite new so don't be too hard on her. But i must say that this is bad even for a simple mistake. HeadSqueeze needs to do some clarification on this.

[@H3adcrash]

I think 38 cubic metres of soil weighs more than 100kg.. Not to mention that they removed another 70 metric tons of ground in 2008 to stop it tipping over.

[@n68bedard]

She should of check the facts' before making a video

[@H3adcrash]

Nous Refuson Indeed!

[@និត្យពិនិត្យ]

Great explanation!

[@BS-sm8kj]

Great video 👍thank you 😊

[@jeffstike3195]

The 10 ton on the opposite side of the leaning tower is Genius! It's like a sea saw!

[@TheKurtsPlaceChannel]

Very nice video and fun to watch. Have a nice day.

[@ChristianJiang]

Thank you for uploading!

[@SCARSAC]

i love this channel!

[@BigCactus23]

thank you I had to do a project about the tower and I had to make a connection this really helps. thanks

[@AliHSyed]

fascinating, thanks guys.

[@abaetol]

This was really cool.

[@akaMyThought]

I liked the info in this video

[@mattorama]

15 and a half tons? No chance in hell. I work in construction for a living. I've dropped piles on houses that held that much ALONE, and this is just a wood framed house. The tower of Pisa weighs a SHIT TON more than 15 and a half tones.

[@joenader91]

mattorama that's just the weight of marble you douche

[@rob11s]

Are you sure about the "100 Kilograms of soil"? Because that's only a couple of sacks of dirt. Try to imagine that amount of soil being dug out in a course of an year... That's literally 5 minutes worth of work with a shovel for Christ's sake...

[@flash2989]

It leans because this tower was meant to be 100 meters, but at 55 meters the tower couldn't last anymore and it leaned to south. saved 3 minutes of your life

[@evnellborgna7895]

thank you for helping me

[@greenghost2008]

I wonder how many tough guys push up against the side and try to stand it straight.

[@TheJamesBondTheory007]

This funny gril recommended this... do not regret it!

[@Christophe_L]

2:53 100kg of soil doesn't sound much to take a year to dig out, does it?

[@Tupster]

2:45 I weigh more than 100 kilograms... What?

[@rudi-gs2pd]

Wow at 2:56 5 degree angle looks like 85 degree. They should have shown 5 degree angle with the vertices line not with horizontal.

[@DannyKeeley]

Please can you do this: How does a humidifier work ? Why does vibrating water turn it into mist ?

[@HotPickle_]

Yep, wiki says it weighs 14,500 tonnes. not 14.5. I'm quite disappointed about this video.

[@xxdemonxx5307]

Lol tonnes

[@MrOlaKulen]

Nice!

[@cosminemilpopescu8533]

I balanced my house with a sack of potatoes and my cat

[@Xoliapydon]

I'm surprised you didn't speak about the tower's center of gravity. Even though the tower is leaning its center of gravity still passes through its base.

[@sirkibsirkib]

100 kilograms of soil? just a hundred? lol

[@klaasbarends]

Shouldn't take more than a few seconds with modern equipment ;-)

[@ThatGuyCanmanNC]

TL:DR the tower was built into marsh land and they piled things on the northern side then dig up the ground a little

[@megeales9205]

I have a fact about the leaning tower of piza that will confuse 99% of you. The leaning tower of piza is at a 3.99 degrees angle whilst a tower of the castle in Wales (Castell Caerphilly) leans at a 10 degree angle. Each year the leaning tower of piza has 5 million visitors and Caerphilly castle 900,000. I also want to say that Wales has so many tourist attractions that are never recognised. Why is this then?

[@Rowgue51]

It's kind of silly that they didn't just straighten it up completely and make it completely stable. I guess they don't think people will want to come see it anymore if it isn't leaning.

[@liamjmbtaandrailfan2791]

Rowgue51 yeah because it be just a tower

[@Khloe_dancer_model]

+Liam J mbta and rail fan ohhh,so is historical because is leaning..but that's it.FUNNY! lol! and that makes it unique, then.Because the soil is wet!.Wow, how we see the world as interesting...

[@ahmedshaglane8104]

"Leaning"tower of pisa for a reason

[@MShermesMS]

Its weight is estimated at 14,500 metric tons and not 100kg but 100,000kg of soil

[@ivo3185]

Could you explain how the Statue of Liberty was built?

[@Tomnews-gm6pr]

I learned about the Pisa tower in school

[@rooktheraptor24]

Pause at :56 The dotted lines don't follow the contour of the building. What is this?

[@Groaznic]

@Head Squeeze, are you sure they fixed everything by removing 100 kg of soil? You know that's just a couple of bucketfuls.

[@thunder230mph6]

What's even worse is the fact that the tower is now leaning right towards the cathedral it was built near, if the tower ever falls over, it could not only destroy the adjacent church but also kill hundreds of people inside!

[@TheManwithafan]

So is the tower open to the public now?

[@habibiak]

I hoping to see some footage of the tower not her face.

[@kenrutherford1109]

I'd rather see more footage of her face and less footage of the tower

[@xapemanx]

y they no just jack up the low side and fortify the ground?

[@trayner]

Whole time I was watching it thinking those numbers can't be right

[@snoop_doge616]

if you're leaning on the leaning tower of pisa, are you actually leaning?

[@mreh91]

It's because bad construction made it lean when the third layer was put on and it leans a little more every year.

[@Calispeedboi]

Its weight is estimated at 14,500 metric tons

[@HenkJanBakker]

But isn't the real question: Why didn't if fall over 800 years ago? How come it has only leaned so far and...stopped 'falling' back then? And why did it start 'falling' again.

[@ThesanRep]

to be honest it leaned very few till 1800... then an idiotic archeologist proposed to solve the leaning problem pumping away the water in the soil... and the problem got VERY worse... in 1990 the lending was at 4.5 degrees (close to the point of no return of 5 degrees) so the consolidation problems were no more deferrable.

[@ThesanRep]

"Why didn't it fall 800 years ago?" Because the construction site lasted 200 years... in so much time you can "correct" the problems of the leaning (at least... a little) that's why it lasted 620 years with no maintenance.

[@mikechildmusic]

Hmm. 14,5000? Did you mean 14,500? We'll get there eventually :D. Enjoying all the videos though.

[@TheEclipsonaut]

Who did the research for this video? The tower weight is 14.5 tons of marble? Are you kidding me? They removed 100 kilograms of soil and stabelized it with 10 tons of lead? Come on this is a joke, is it! Next time do your job a bit better, please

[@biondibrunolol]

Totally agree, they should make sure of being able to read their datas! the tower actually weighs 14 THOUSAND TONNES! just for comparison the "David di Michelangelo" weighs about 6 Tonnes and it's "only" a statue, a very big one though

[@n68bedard]

14.5 tons that was her first mistake insted of 14 500 metric tons

[@n68bedard]

and you are right its not 10 steel of weights but 10 tons pf lead :-)

[@Carhill]

Had a chuckle when she said 100kg's. That's nothing.

[@Groaznic]

Not even the graphics team managed to think the numbers through when they rendered them on the video. I thought they're supposed to be a team of educated computer geeks? But apparently they just do their job to get some money no matter what crap they are instructed to put in the video.

[@LisaBeergutHolst]

Diamond in the back, sunroof top Diggin' the scene with a 5 degree lean, wooh...

[@llaverick]

Quite frankly, this video should be removed, remade and reuploaded. The measurement errors make it not factual and to me it's a bit silly to leave it on and mislead people. Don't get me wrong here, I love Head Squeeze and this would be a great video like all the others were it not for all the errors. Please fix and reupload Head Squeeze! :)

[@n68bedard]

lol 100 Kg = 220 Lbs of :-P not thrue it was by removing 38 cubic metres (1,342 cubic feet) of soil from underneath the raised end. The tower was straightened by 45 centimetres (17.7 inches), returning to its 1838 position. After a decade of corrective reconstruction and stabilization efforts, the tower was reopened to the public on December 15, 2001, and was declared stable for at least another 300 years.

[@Bastoto]

At your last sentence, I guess no one will live to see about that😂😂

[@avis9086]

how do you know all of this

[@blackbirdpie217]

I didn't know the walls were made of mobble and rubble. But yeah the quantities of weight of both building materials and earth removed seem a bit puny. I assumed there were a few digits missing. So 14 kg each day for a year would equate to approximately five thousand, one hundred ten kg or eleven thousand, two hundred sixty five pounds, or 5.6 tons of earth. Sounds more plausible. Now I have to go find out what mobble is.

[@arturomontes8008]

[@williamcrane1886]

Nice thing about the Tacoma Narrows bridge is it tore itself apart, we learned from it and we moved on. I'd say we learned all we needed to from this constant problem of an eyesoar. Push it over and get on with life already. Stop wasting money on an engineering mistake. Really, they've been trying to save this thing for 8-900 years?

[@TheHuesSciTech]

It's saved. Also, it's a tourist attraction. I encourage you to take your suggestions to the council of Pisa, you'll probably get laughed at. Also, as an engineer, it's an entertaining and unique problem. I would have loved to have been involved.

[@ThesanRep]

Seriously... do you have even a pale idea of how many tourist would go to Pisa if the Tower would be straight or just a big mountain of marble ruins? Very few. Just the amount of taxes the city has taken from the hotels and from the shops is enough to keep the Tower safe for another millennium...

[@MasticinaAkicta]

As the others point out it is an attraction. It attracts many tourists. Tourists put money in the local economy, they sleep in the hotels, they desire to go out on dinner. They might even look at more old stuff while they are there. Guess what that is allot of money going round. I definitely would know it if I had something like that in my town. I would do my best to keep it. Tacoma Narrows bridge was different. it might be saved.. if they had though of cross beams or other structural improvements by then. But they hadn't. And if you fix Tacoma Narrows Bridge.. really how many people would go there? Or in GTA san andreas, there is a small town with the biggest cock. Oh yes that rooster is huge! Actually that defines that town. In the end it is about money.

[@williamcrane1886]

Well it certainly is an engineering marvel. But then I wouldn't go to Pisa anyways so obviously, not my thang.

[@annabelhunt565]

guys chill your beans...i think that they only removed 100kg of soil in a year because if they removed too much at once, then it would have been too sudden for the tower to cope with!

[@ekscalybur]

You do realize that you can get more than 100kg of soil into a single wheelbarrow? That's a single guy with a shovel and about 15 minutes of his time. In other words, she's a talking head reading copy that wasn't researched. This is so amateur that I'm embarrassed for them.

[@EmporioZuagroast]

i have personally shoveled hundreds of kilograms of soil per day while i was helping a friend renovating his house. literally with a shovel. 100 kilograms is not even a wheelbarrow full of soil. 100 tons would seem more fitting. thinking about it, every single number in this video seems to be off by 3 orders of magnitude. looking at wikipedia reveals that this indeed seems to be the case. the tower weighs about 14500 tons, not 14.5. ಠ_ಠ

[@st2en]

14.5 tons of marble? 100kg of soil? Was checking it this was released on 1 April. Anyway, it is not the first time a Head Squeeze vid is factually incorrect. The one about paper sizes states that A0 is 1m x 1m...

[@Tzoggy]

Calm down people, it actually weighs at about 14,500 metric tonnes.

[@n68bedard]

no 14 500,00 metric tons

[@johmcg64]

Why don't they dig under it carefully and make it perpendicular?

[@loganqueenan4937]

Probably because they used to use their arms and fingers and pacing to measure so their measurements were really off

[@UpsideDownMon]

why not just build an arch on the side it's leaning towards doesn't seem like it would be such a problem

[@TheHuesSciTech]

Would be ugly.

[@alexscott75]

Only 100kg? I don't think so xD

[@Nytemarezxz]

It's an obelisk and national monument at the same time.

[@stanley8441]

They took 4 bags of compost worth of soil out from under it (100kg)? The marble in the tower weighs 14.5 tons? This video is not correct ignore it Edit just seen retraction. Still how did they mess up 2 times

[@NameName-dg7nv]

did you mean 100 tones?

[@GetOutsideYourself]

100 kilograms? Really? They filled up a couple of wheelbarrows? That's pretty drastic.

[@dwaipayandattaroy9801]

The Ratneshwar temple near Manikarnika Ghat located in Varanasi, Uttar Pradesh, India, leans by 9 degrees, which is 5 degrees more than the leaning tower of Pisa.

[@someone-if8ce]

Dude the tower began its construction in late 14th century and it leans because the architect made it on a soft ground edit: oh and it was for a bell tower lol
