Are Spider Webs Actually Stronger Than Steel? | Experiment

- Could spider man swing on actual spider silk? Would it be strong enough? Today I test out this question by comparing spider silk and steel tensile strength to see which is actually stronger. First I locate a good spider web made by a garden spider in my garden. Then I make the necessary weights to add to the spider web incrementally. The spider web holds an amazing amount of weight for how thick it is (over 400 Mpa!) Then I use that tensile strength to determine the amount of weight that a 22 gauge steel wire should be able to hold if it is the same strength.

So cool man! My daughter, who's in first grade, brought a book home from school about spiders. It said spider silk was stronger than steel and she didn't believe it. So I looked it up and found this video. I think she gets it now 😛 Nice demonstration!
That's great!
Bet she's gonna be one smart person when she's older
I think my great grand kids will love this . I shared this on Facebook. Thanks
Awesome!
Great grand kids? Jesus
This is a very BASIC demonstration of strength comparison, and in that sense it is good.
That being said, and as stated numerous times in other comments, there were a bunch of errors causing flawed results.
The most obvious is the fact that the weight placed on the web was spread over the distance of 12 pipe cleaners which are probably close to 1/8" diameter (give or take), whereas the bucket was located on a section of the wire approximately 3/16" wide. It's common knowledge that the pounds per square inch applied to the wire was greater than that applied to the web.
Secondly, as you were outside the wind resistance applied to the cross section of the pipe cleaners amplified the amount of force being applied to the web, I say force because at this point its more than just the weight of the pipe cleaners pulling on the web.
Now some might say that the factor of you dropping the weights in the bucket is the same as the factor of the wind but that won't be accurate.
Thirdly, the fact that we can't determine from the video (accurately) if the web broke or just disconnected from the branch/leaf.
There are a few more things that were not taken in to account in the experiment, that others mentioned besides these.
However, I have seen other experiments done regarding the strength comparison of steel to spider web using the breaking point LENGTH wise of the two. End result? spider webs are stronger then steel.
So, as I stated, thanks for a great albeit basic demonstration that is something any kid in school could use to grasp the understanding of just how strong spider webs can be. I'm just thank full that we don't have Godzilla sized spiders....
Awesome video! I’m happy to see people like you going out and performing hard science for viewers, without the need to add superfluous graphics or distracting jokes. The production quality isn’t the best, but the information quality more than makes up for this. I hope you’re still making videos and I look forward to seeing what else you’ve produced. Thank you!
There's a huge amount of error and uncertainty in your experiment. Not least of which is the way you're dropping weights into the bucket hanging from the steel. This isn't a dead load that is applying even stresses on the steel wire, it's a dynamic load that is putting far greater tensile stress on the material than the masses of the weights themselves because you are accelerating them by dropping them from nonzero heights. Also, "steel" is an open-ended term--there are many different varieties of steel. Structural steel members are graded in ranges of 36 to 65 ksi but some braided tension cables can withstand over 200 ksi of stress. There is also the confusion between strength based on weight and strength based on volume.
+Nate B. I dropped the weights on the spider web too so...The points you mentioned were not actually a huge factor of error. The biggest point of error that you didn’t point out was that I estimated what the diameter of the spider web was.
@@ActionLabShorts it is a bad example for sure. The end to end support is not the same and webs being on leaves it allow it to have be more ductile
@@Goatwho but it still fact that spider web are better and you could see that the spider web got slip down and not actually break
ActionLab Vlogs you needed to make 5 lb hooks with a comparable diameter (similar to the pipe cleaners vs spider wire dia) to hang as to not make a pinch point on the wire. Spreading the weight out on the cable would of helped some but I think it still loose to spider web. I’m guessing 45-47 lbs.
what did you expect from someone who does not use international system for its measurements? Ofc it's not accurate.
Your experiment was flawed, the spider web didnt break it slipped off the leaf.
Alexander Carlson not really because he still said spider webs are stronger
if it slipped off then that means it could have held more weight. either way, it still held more than the steel wire which means its stronger
Well its still stronger
i should also point out, so was the steel wire he didn't take the bucket into account
@@mm-fh1tw The whole point of an experiment is to get actual values, like "spider webs are X% stronger than steel" or "spider webs can hold up to X times as much weight as steel". Saying "spider webs are stronger" is true but it literally means absolutely nothing and its impossible to interpret. Therefore an accurate experiment is required.
WOW! That is amazing! l can't believe that a spiderweb is that strong! Great calculations going on there, simply amazing! Great job, keep em coming!
Working with this low amount of weight, the air pushing down on the pipe is such a great factor here and will give u bad results most likely
If u could make a spider web big enough it would catch a jet in flight
Bro it was just a normal spider web imagine the spiders in the jungle with more strength !
Mayank Mhatre yeah like golden orb weavers or even darwins bark spider!
Amazing experiment! Always wondered about this.
When comparing spiderweb to steel doesn't the elasticity play a huge role?
the problem in this experiment is in distributing the load on the spider thread. while it was point load in the case of steel.
no doubt the spider thread is stronger but the experiment is not fair .
i actually made artifical spider silk
This is a great video. I like it.
So in a nutshell spider webs as a molecule is a good bit stronger than steel but due to how thin the thread is it can show these properties off.
Meanwhile in the spider's world 🕷️🗺️ : *WTF these black oldman sticks are doing in my home* 🕸️
could it be possible that the spider web could be even stronger? we dont know where the spider web broke or pulled off the branch where its attached? cool video!
I was thinking that, did it actually snap or pull away from the branch
UA-camUser no most spiderwebs are different from eachother
Matthew Wilson yeah , if you feed spiders with graphene their webs will be way stronger
Hmm check darwin bark spider's web... It can make bridge for 25 meters long
Spider web:
Total material problems...
Technology problems solver.
I'm surprised the bucket didn't break before the wire.
Steel wire should be to scale being much longer. Also many variables apply here. You can see the steel doesnt ha e much flex while the web has lots of bounce and flex. The web having thos flexabilty aloowes it to have more flex at the holding points.
Compared to spiders, yes.
Good work, i feel like zero error
I think that calculation is wrong because you didn't consider the tilting angle of the tension in the spider thread
The weight force is equivalent to the net of the two tension tilted forces at the spider thread
So what you're saying is that those 12 little floaty thingies are equal to 35 pounds?!
Imagine that strand of spider silk is the same thickness as that steel string, that strand still cannot hold 35 frigging pounds!
So Superman should be called Man of Spiderweb.
From what I heard from some chemists and metallurgist, spider webs are actually very darn strong in fact there have have been comparisons with thicker spider webs with the same strength as high-quality kevlar, the very same material used largely to make bulletproof vests and body armor.
Researcher have also still been unable to completely decipher on how spiders are able to produce such strong webs that can effortlessly hold insects or objects, which are more than twice it's weight till this day.
i actually made artifical spider silk
the bucket hold all the weight from the steel. why didn't you put a candy cane shaped metals rather than using a bucket? For me it's kinda unfair x)
How do u know that spider web have exactly 5 micron diameter?
Probably Google
You must try the golden silk orb weaver, its more stronger than any web
Have you took the angle between wire parts into account?
If the web was vertical and not horisontal I guess it could handle more weight?
there are flaws in your experiment. you have variables you did not control. for instance you didn't consider the tomatoes branches movement.
GRATE demo experiment ,
spider webs are a super thugh fabric material used for rock climbing ropes .
they are NOT stronger then steel though , (not in EVERY way ) but rather more FLEXIBLE ,
for example if you take a sharp axe and chop 2 wires of 0.6 mm placed on a lathe ,
the one made of spider web silk it will brake first ,
or if you run both of them on the edgg of a shap knife = same resault
spider web is only superior in tensile stranghth (pulling and streaching) , but not impact and sharp friction
it is a grate material simular to carbon fiber ,
it will be used more as a technology even at 2070
good experiment
Wouldn't the bucket being in on part of the wire (rather than across it like the pipe cleaner hooks) mess up this experiment?
+Nathan Young good point! Yes it concentrated it in one point vs. being spread out. I can’t believe I didn’t think of that!
According what he did ...shouldn't the tensile strength of spider web be 8.61 MPa ? And what is up with that 2 multiplied with Pi in denominator while calculating tensile strength of the spider web ? Every calculation is flawed.
you made some errors in you're calculations because you not only didnt (could't) observe where or even if the web broke or just pulled off where it was attached but you didnt count for the surface area on the string of web and the string f steel that you covered in each test. for the web the covered surface area was wide giving the web more of a chance to balance that weight while on the steel all the weight was in one singular spot causing more tension than dispersed weight would
this guy seams like the most simple minded guy can get simple minded
You had a bucket, why not use water as a weight? Dropping the weights in the bucket causes a higher instantaneous load. And what steel alloy did you use? I think something like piano wire would be an interesting comparison.
Larry Scott to be fair, the spider web also had instantaneous loads with the pipe cleaner dropped onto it
Now forge a sword from spider web silk
it depends on what type of spider it is...
great.. i am going to do this in my classroom
Hmmm... but what if you burn it? Now see what's stronger.
Cool.Never believed that,Do now!
I know, me too!
Spider webs are stronger than the titanic?!?!
Good try but it is a bad example using wild spider webs. U dnt know how long its been there and u dnt know how well in contact is the support ends of the webs
Spider web is strong than steel huh? You know what that means?
Spiderman is stronger than Superman, a.k.a. The Man of Steel!
awesome
Try hitting them both with bare hands and you will see that steel is stronger
that was exciting to watch, I thought steel would be stronger,and a stronger spider web was just an urban mith
Yes, I wasn't sure either. I was a little surprised at how strong the spider web was!
"dont want to get hit the wire". Looks like you dont understand physics after all. If well anchored it is clearly going to break in half and the lenght is obviously not enough to reach you + there is no reason whatsoever that the wire should fly upwards.
You should use hooks, man.
Then y can't u use a spider web in parachute....
Lame experiment but interesting!!
Next time, check if spider web broke or slipped off the tree branch
Don’t be scared of placing the weights in the bucket.. don’t drop the weights, the impact weight cause the steel wire to sag and ultimately breaks
Can you cut a mirror with lazer light
I think it is faulty because you didn't take the length of the spider web in your calculation.
ur moms faulty
oh snap
Compared by weight the silk is stronger
You proved gravity strength.
news flash can a spider wed stop bullet
I still don't get this theory. How is a spider Web consisted strong when you can literally break it with one finger. Hanging pipe cleaners on it doesn't prove its strength,or does it ...I'm so confused on the mathematics. I failed maths yeah but this is just so hard to grasp.
CodyDTD Well the silk is only 5 micrometers thick.
So if it was somehow threaded together to make it as thick as that steel wire it would be pretty hard to break with just a finger lol but I used to wonder the same thing.
A darwin bark spiders web is 10x stronger than kevlar
spider silk
Sure spider webs are stronger if you cut something into very very small pieces nothing against the vid but it’s annoying when somebody says spider webs are stronger than steel , sure it’s stronger than steel wire but I don’t see any buildings made out of spider web
Darwin bark spider web is the second strongest organic material in the world
I say bs wind factor better test would be indoors
why is this being recommended in 2021?
I need that web
Don't you have to use the same density of spider web as steel to make this experiment viable? Like a single strand of spiderweb obviously won't be as strong as a 5 lb hunk of steel lol. Try 5 lbs of web maybe? Idk
+George Washington well, you just need the same weight per cross sectional square area. The densities don't need to be the same. The point is that if you have a web strand and steel wire that have the exact same diameter, the spider web will hold more weight.
I broke a spider web w/ my hands does that mean im John Cena (0o0)
It didn't break it just unstuck
So that means Spiderman is stronger than Iron Man??? 😱
so i can be spiderman
shabby
Please please please use international system ... What is a lbs D:
@Dan C. It makes more sense using international system, then dumbfucks can translate the measurements to their useless units.
Find out the mathematical secret
So Spiderman’s real?
12 of Those little candy cane things count NOT have weigh 63 pounds...... Bs
Bananna Cream Proportional weight. The silk thickness was measured in micrometres. The steel line was much thicker, so more weight was needed to balance the proportion.
Amazing, can't believe it held so many pipe cleaners 😲 By the way, that tomato in the background looks a bit like a penis 😝
I See His Face
I Hear His Voice
I Exit The Video
Just give me an answer
Insta sub.
thanks!
It saved a prophet's life .
👍🏾💯
Answer
Yes
WTF I thought it's gonna hold 7 or something
Lol
Who's here because of his new video?
I KNEW IT! I was banging my head thinking I had seen this but couldn't figure it out where now I know where. I assumed it was a deja vu or something but it felt more real...
?
Anyone here because of discovery science?
Wow, this is the most flawed experiment ive seen on your channel. Still interesting tho
Piss poor test
Once again, nature proves Human engineering to be pathetic
steel is stronger
stronger than steel or spider web?
Bonzi dude your wrong get more research
