K'nex Bridge on Daily Planet

My 5 mins of fame on Daily Planet! Big thanks to all my friends and family for their support throughout this project.

[@modifierle]

I love your description of the risks and dangers if it fails...so vivid

[@Wanderlust1972]

he knows the dangers, so brave

[@ErikOosterwal]

You'll put an eye out, kid. 😉

[@adambyrd7499]

Andrew: Yes I'd like to buy all these knex pieces please Cashier: that'll be $30,000 please (pays with his entire college fund)

[@LawnFlamingoPoop]

he made that sound like he was a daredevil for attempting to cross it

[@AlexEatonPDPIGaming]

Power of the triangle... **Illuminati theme plays**

[@Request_2_PANic]

I guess it was coming sooner or later.

[@AlexEatonPDPIGaming]

+Paul Noonan :D

[@mac6]

Alex Eaton just wondering if you forgot you left this comment

[@matthewburghard9171]

Not do be a douche here, but he could have easily made the bridge support all his weight without the towering additions. if he utilized the multidirectional peices more and made "X" beams with multiple beams between each layer he could have made a flat platform that would have supported up to 2000 LB's WITHOUT using plexiglass OR using giant towers.

[@jakeryan8350]

what are you waiting for?

[@Mikeological]

That's not being a douche. That's giving constructive criticism. It would be douchey to do something like call him an idiot.

[@howardbaxter2514]

Like Mike said, that's not a douchebag statement. You would be a douche if you said that the plexiglass is what made it work so he cheated.

[@simonkoeman3310]

howard baxter let's be honest with ourselves. Without the plexiglass his foot would have punched through the bridge an it would have failed. K'nex can't take the pressure when it's that focused. It's the equivalent of putting snowshoes on.

[@SirFloofy001]

The plexiglass just took the place of a large flat knex piece (which they don't make) The plexiglass was supposed to be the steel panels that are laid out on top of the frame before the blacktop is laid.

[@MrFoxANDnoobie]

Wow this was made 2010 and it’s still the strongest knex bridge I’ve ever seen

[@MrFoxANDnoobie]

2012*

[@Superchad245]

what was the maximum load for the bridge

[@annachristofides8397]

100000000000000000000000kg

[@adammartinelli8274]

Pause at 0:24 for humor.

[@Alex-oz9eh]

Adam Martinelli amazing

[@redtime-lapses8070]

Adam Martinelli I

[@cup_and_cone]

What am I looking at? The guys stoner "I farted" face?

[@duckgoesquack4514]

the girl has a lip thing going on, if you pause it just right moment 0:23

[@mcCheesyable]

i got so hyped when he made it to the other side keep it up man!

[@FrankDaBank25]

Go sit in your jail cell sir

[@adamburns7356]

have u got the instrction booklet for this

[@deans-rewind2882]

That's amazing! Great job

[@niekesselbrugge1132]

Anyone could make a bigger and better one. You dont know what talents people have. But i am still goddam impressed.

[@knexbridgeguy]

lol, yaaa....it was my disclaimer incase someone attempts something similar and does hurt themselves.

[@NoahSmithknex]

Sweet! I build K'nex roller coasters :) Nice job! It's amazing. :D

[@danielbuijs8647]

That's INSANELY AWESOME!!!

[@J_PIK]

My 4 yearold just said "That's awesome!" He is getting Knex for his 5th birthday; the 70 model set. :D

[@markdaoud]

Love it!!! Way to go Andrew!!!!!

[@stephensummers1958]

Pretty cool. But I feel the plexiglass is cheating. Sure it will help his feet not go through the cracks, but it will also greatly disperse the weight across a larger area.

[@xapplimatic]

The Plexiglass probably did a fair amount of the heavy lifting as far as distributing much of the weight to the Knee members... Plexiglass in modern times is VERY strong. Some styles are 500x stronger than glass in certain stress case scenarios. Thats what hey use it on the fromt of soda machines etc to withstand the public abuse machines get.

[@alvaradoac21]

The magic of engineering!!!

[@KingKiller43]

Nice job man, the suspense was overwhelming while you were walking across the bridge.

[@ArmtekGizmos]

Try making a Rube Goldberg Machine that goes from the second story ceiling of your house, travel through every room of the house, and end at the tip of your driveway. It is definately not a task for kids!!!

[@Hammerfall541]

Cool bridge it's just goes to show that your toys can be useful if you have a vision.

[@ajg8600]

4:36 I'm sure his neighbors really appreciated that

[@OliverUnderTheMoon]

Yes, how abhorrent of him to momentarily interrupt their mundane suburban solitude. He is probably out there every night wooping away at the incessant completions of his Kinex civil engineering projects. God only can know how they can stay focused on America's Got Talent with that inane pandemonium happening outside.

[@knexbridgeguy]

definitely sounds like a challenge! And I do love Rube Goldberg machines, however im a bit busy finishing my undergrad right now. But maybe in a few years!

[@brandoncdude893]

That is allot of parts, is the plexiglass considered a K'NEX part? If you had more parts, you could use small rods instead of bigger rods. I made a small platform that was 4 inches thick and it did not break on me when I stood on it. I weigh more too. The only thing is that it is much harder to take apart.

[@Firestar-rm8df]

Brandon Cunic how long was it though? Did it span the same distance as this one here?

[@brandoncdude893]

It was only a platform to stand on the size of a scale just to see if I could stand on it without it breaking. I can't get over how many parts you have! I have a rubber band ball that weighs a half ton that has been sitting in my garage for 12 years! I can't find someone to display it so I can work on it. I should turn it loose!

[@DennisCosteaJr]

Plexiglass true. This bridge structure would not qualify as an all K'nex pieces structure if he wanted to get in a Guiness Book of Records, but it is a pretty cool example of using something simple to accomplish a more complex job! Building pieces with such simplicity SHOULD play a role in the human colonization of Mars! Seriously. If one small piece fails or gets damaged, remove it, replace it, and carry on! Universal sheets and girders, snapped or bolted together, are easier to manage than entire prefabricated girder spans, walls, floors, etc.! I predict here and now that Gorilla Glue and Gorilla Tape (3x stronger) will be used on Mars one day! ~ And if these aren't, what an incredible product endorsement "fail" that will be!

[@CockpumpVideo]

I am not sure how nuch danger you were in of breaking your neck or getting stabbed by high velocity k'nex pieces..lol

[@stanja28]

I'm so glad regular bridges aren't made out of k'nex

[@puzzle_em]

Seems like his feet would have broken the through the pieces if the plexiglass wasn't there! But very well done bridge:)

[@ACDC5968]

Oh my gosh that things amazing so how much did it eventually hold. This video needs to be see by so many more people I give you so much props for this I can't imagine building this because I know eventually your hands get raw and it just hurts. So how long did it take to build

[@Dendrowen]

It's easy to say it could be made less complex. Don't do it unless you can actually show that it is, in fact, easier.

[@gazelle1467]

Is that Elon Musks illegitimate son

[@knexbridgeguy]

you`re right, i could have built a bridge deck out of k`nex, it just would have taken a while. But thanks for the feedback!

[@knexbridgeguy]

The bridge eventually collapsed under my weight due to fatigue of the material, but ya, my fingers did get very raw in the 3 months I spent building it!

[@Tornadoman96]

This deserves WAY more views! That's awesome! However, wouldn't it have been stronger to use blue connectors and green rods to make a stronger floor?

[@EricPeelMusic]

Adds a lot more unneeded weight, possibly requires all other parts to be stronger and heavier to support that extra weight.

[@mattrockman1028]

my mom is gonna throw a bridge party. we got doritos cause theyre like the triangles i lernt about.

[@knexbridgeguy]

thanks man! I checked out some of your videos and looks like you know k'nex pretty well!

[@tyler3337773]

wow man great job

[@gabrielsandez1143]

Nice very cool

[@SpeedCoasterMaster]

AMAZING!!!

[@ArmtekGizmos]

I make Rube Goldberg Machines. One of the hardest challenges on this planet.

[@knexbridgeguy]

it would have looked pretty neat, especially with one of those fancy slow-mo cameras

[@BlueLionX88]

Congrats sir, you are an official Badass Andrew M.

[@justindtackett]

That kids fingers though, raw i bet

[@bitz5729]

all of these people are saying he cheated with the plexiglass.. but he could've just made a sheet using the white circle knex and the green connecters and it still would've worked, it was just for convenience

[@jamesbizs]

Yes, but then it would have been a true k'nex bridge.....

[@GRAAAAAAAAAAAHHHHH]

That is amazing

[@SpeedCoasterMaster]

Now make a knex coaster you can ride in :) I can't stress enough how many views this deserves...

[@TheaDragonSpirit]

You can join knex in a way to make a flat part, If he had done that till it was about 3inch thick like a plank of wood it would have been more compacted and would not of broken, in fact it would have been more solid than wood. Just saying it was a little over designed. But still nice.

[@Sarge92]

+TheaDragonSpirit it would of bent each of those little joints has a little play in them infact if you take say 10 meter long strip you could actually bend it atleast 45 degrees thn the conectors all pop out there sockets you could make flat parts but then youd have to do some complicated engineering on that also

[@SirFloofy001]

And then the supporting structure of the bridge would not have been able to support the weight of the deck.

[@kaneellison1592]

WOW!

[@knexbridgeguy]

Thanks Mark!

[@Timmyval123]

The plexiglass helped a lot tho

[@knexbridgeguy]

No way! Where? I'm at the University of Ottawa for Civil Engineering! One semester left!

[@ACDC5968]

Well im still in highschool and im in pre-engineering but i plan to do mechanical engineering because i just find it to be more fun for me im not sure were i want to go to college but im going to look around you can kind of tell want to go into mechanical engineering just look at my videos i love building hopfully the most efficenty trebuchet or catapult in the world because i compete in punkin chunkin and one day i want to hit the mile mark that is so elusive.

[@---rollercoastercreator---5596]

HOLY SHIT MAN!!!

[@niccatipay]

I somehow came from MegaStructures... you must have done a good job. *watches the video* *B O I*

[@knexbridgeguy]

yes indeed

[@jacobpearce1266]

Well done you made it omg

[@Koolcoasterkid]

Very nice bridge. How much did it eventually hold? Check out my ball machines on my channel. They use almost the same supporting technique. The beams on my ball machines are extremely strong.

[@Obsidian0Knight]

the plexi glass changes the way his load is applied....

[@smoop3256]

Sweet

[@Request_2_PANic]

What were the results of weight capacity?

[@dytakeda]

Why did it have to be over the pool?

[@Wizard-ol6vw]

600th like

[@tarzanfpv3750]

what program did you use

[@knexbridgeguy]

For the design? I didn't use anything. It was all in my head.

[@mnwebsource2286]

Amazing build! If you need parts, check us out, we have any Knex part you need!

[@tarzanfpv3750]

at :35 it shows papers. was that drawings you did your self

[@uyou2tube]

very cool. i think the plexiglass part is cheating. he should of made the deck better so you could walk on it. plus WHY NOT show it collapse as you jump on it in the middle! now that would be entertainment! splash!!

[@SirFloofy001]

The plexiglass is not cheating because his bridge is just the framework, which is how they build bridges like they, they assemble the framework then lay a deck across it which is usually steel plates covered in concrete or blacktop.

[@jamesbizs]

+ Nix Ryu The Sergal Nix Ryu The Sergal no, it's still cheating. It's spreading his weight out across more points. It's no longer just a k'nex bridge. By that logic, he can fill it with concrete, and claim it still counts because he built the framework out of k'nex.

[@SirFloofy001]

No because bridges arnt filled with concrete, not the old ones at least. But they ARE covered in steel to spread the weight of heavy vehicles so that an 80,000 lbs truck isnt putting all its weight on one I beam

[@dannygjk]

Bridges have a flat area on top for vehicles to drive on. This bridge with a flat surface is essentially the same thing.

[@TomBom292]

Real bridges do that with layers of concrete, steel, or blacktop on top of the framework

[@ACDC5968]

its funny you say that because i am trying to go into a mechanical engineering

[@lucasmadaris5485]

3:27 K'naxses XD Bruh

[@clkid10]

WOW, um, you make bridges and I make K'Nex coasters. Now lets swap challenges, I build a bridge and you build a huge roller coaster, tell me if you quit :D BTW, nice job, I gave you 10 more views for you!

[@speedytoast9689]

Noice

[@CockpumpVideo]

hear that..but it was a great build though....

[@BellaBehindAKidBehindACamera]

Yea sure man

[@smoop3256]

He's smart

[@SirFloofy001]

Aww i wanted to see him over weight it to see how strong it actually was.

[@daltondeal247]

Do u think I'm stupid? The plexiglass evened out his weight and was much easier with that that

[@SirFloofy001]

Yeah, that's how bridges are built.... engineers build a frame with lots of holes in it then lay steel plates across it. Has nothing to do with whether your stupid or not.

[@er4795]

i find that any knex creation with the use of anything else is cheating though i dont find that overclocking the engine is

[@SirFloofy001]

Knex doesnt make large flat pieces, and if he made a deck thick enough for him to stand on it would have been to heavy for the bridge to support. Bridges built in this fashion do the same thing he did, they build a frame out of steel, then lay flat steel sheets across the bridge to make a deck. If you removed the deck from an old bridge you would see that all there is under that steel plate (the plexiglass in this bridge) Is a steel frame. this is dune because it saves weight meaning the bridge can safely hold more weight.

[@CockpumpVideo]

good build though...

[@alexthefoodiekid6440]

What! !!!
