Real Captain America Shield That Actually Bounces Back! - OVER 100 FT BOUNCE!!! 

“Evacuate the city, engage all defenses, and get this man funding”

Welcome to the cap club! Couldn't have done better myself, I never imagined a bouncing shield would work that well! Definitely a potential real product, you should try and partner with Disney to make them!

What a simple build! This is one of your best projects! This looks so much attainable and is so close to the movie and comics. Like that ratio is perfect!

A note for the future if you wanna try this again; carbon fiber doesn’t have substantial stiffness by itself, it’s the resin that’s super rigid. If you could find an alternative option for the bonding resin, something softer and more flexible while still being durable, you could make the entire shield from carbon fiber with that alternative resin

J: *tries to make caps shield* Also J: *accidentally invents a million dollar toy idea that's gonna make him filthy rich*

That collab with Allen was so fire

I love how you explain the physics behind everything! A real engineer.

That battle with Allen at the end was so shockingly epic!

Surprisingly enough, he actually DOES calculate how the shield bounces back.

He actually can calculate all his shots and that is 100% why he’s so nice with the bounces

You should try replacing the magnets on the shield with a magnetic ring instead, where the diameter matches the magnets on your arm. That way you might be able to catch the shield on you arm with the magnets regardless of the shields orientation

The amount of Respect I have for this guy for always persuing in everything is unimagineable

Science beefs are literally the funniest thing on youtube. Never stop.

I love the hacksmith, but sometimes since they’re so professional they don’t have many failed attempts on stuff, but seeing the trial and error for J, just so much more interesting to watch the actual build rather than just skipping to the final product

your explanation is like a physics teacher

yes the spring ring is awesome

If Sean and JLaser got together - Sean: "Ok so I had a few ideas, first up is the Mark 85 nano tech suit." JLaser: "Let's do it."

@1:10 that’s literally it. The super soldier serum allows Cap to think faster (and see bullets after they’re already fired and heading towards him) so he really does just do these equations in his head with every throw.

Jlaser videos you're MY favorite youtuber

10:58 "where'd you get that road mirror?" *noise of cars crashing down the road*

This is just as impressive as JLaser's more technical builds, IMO. His disciplined approach to the physics, not leaning on electronics for any part of this, is extremely impressive. It would be too easy to slap some swiss cheese on a drone and say "the movie thing flies, and mine does too. They're the same!", but JLaser actually made something that acts just like the shield on screen. And he did it by getting to the root of the physics. Top tier stuff!

Honestly though, "spring rings" sound proper fun to play with

Insane project dude. Keep going

Well done jlazer 4 making that🎉

This is by far your most movie accurate build ever. Very impressed. This may be your finest video

Funny thing is, in the comics, the actual canon explanation for the shield bouncing perfectly IS that Cap can calculate the exact trajectory needed for that throw. He practiced a lot to be able to do that.

Thank you for you building Captain America suit !

amazing project

The rivalry with Allen Pan made this so much better LMAO

Spiderman: That shield doesn’t obey law of Physics at all Jlaser: Hold my calculation

You never cease to impress😊

Bro you have so much time on your hands but what you make is awesome I can't believe it Keep doing what you're doing

This is a great example of conservation of energy, in a system not wanting to be lossy upon impact. It's hard to maintain inherent kinetic energy with something so thin, but by god I believe your solution is great. Nice work Jake.

Dude, that prototype could revolutionize ultimate frisbee

Oh my god, this is AMAZING

wow what a video. especially loved that ending

As a MASSIVE Cap fan, I think this is the coolest shield project on this site.

Frisbee + being able to bounce off walls, honestly I’d 100% buy that

WHAT IS THAT TRANSITION THAT IS CRAZY AFTER U MADE IT

Amazing! Great work! 👏

He’s as brave as captain America, throwing the shield around windows without even flinching

Is noone gonna talk about how fricking smart and genius this is, and people demand more, i mean they're not wrong, this is absolute quality content

"Here's a drone shield: Eat sh*t." goes so hard.

Such a cool design

The "Captain America is just a geometry whiz who can calculate angles perfectly in a split-second" explanation is pretty much spot-on correct. It's mentioned in the movies (and the comics) that the Super-Soldier Serum basically made Cap into what Steve Rogers imagined the perfect soldier to be. So his grasp of tactics and strategy, his reaction time, and his awareness of his environment are enhanced every bit as much as his muscles, skeleton, and metabolism. You can see the seed of what the Serum enhances already present in Steve, though: in the scene where everyone else tries to scramble up the flagpole to grab the flag (getting a ride instead of a hike back to base as a reward), Steve susses out that he can just remove the lynch pin and the pole will fall over, allowing him to pick the flag up off the ground. So the basic ability to figure out efficient tactics and calculate angles on the fly was there, the Serum just cranked it up to 11.

2021: making a captain America shield that actually bounces back 2031: making Spider-Man web shooters that actually swing you around

THIS IS PERFECT! JUST PERFECT! And what a cool video with getting back to that Alan guy. I'm just wondering how is this not a toy yet? I think we all want this

Video is already sick but low key liked and commented cause I love the frisbee proof of concept test. I want one.

“ or Captain America is just a geometry whiz” you’re joking but that is actually exactly what he does. He can just do the calculations super quickly

This is the first "physics-based" cap shield ive seen and it looks like it would be alot of fun to play with

Amazing work!

Hey I man a big fan of captain America and your videos they really help with Science project

"Captain American is a geometry wiz that can calculate the perfect shot" Yes. That's exactly it. His super soldier mind allows him to react much quicker and much greater. He uses this, and the vibranium in the shield allowing it to absorb kinetic energy, to always hit his target and bounce back to his hands..

Three things: One, dope build. Two, of course we need "spring rings", anyone saying otherwise is wrong. Three, classiest and most constructive resolution to internet beef EVER. Keep up the awesome.

whoa you are like the greatest inventor i have ever seen

Epic bounce!

Fun fact: Captain America is actually a “geometry wiz” cuz the super soldier serum made him smarter and the magnet also kinda assists with it coming back to him

I really like the way jlaser handled Alan's "criticism"

Yeah that sounds so cool

I love how you threw the throwing knife at the shield while you were holding it instead of just leaning it on the wall or something

Loved seeing the problem-solving process on the oscillations and getting the shield to bounce. Great stuff as always

Nice work

10/10 amn good job it worked so well.

This is honestly one of the best "made in real life" projects ever.

Fun fact, the fact that cap can bounce his shield so perfectly was brought up in the comics. He spent so much time training with his shield that he could tell how it was going to fly with just a glance.

The battle at the end was pretty good

Technically, the super soldier serum amplifies EVERYTHING. Good, evil, strength, and most importantly, smartness. So captain America is most likely a physics genius

As an engineer I have to say this is your best video to date! I like that you cover your entire process and your development skills have been improving with every subsequent video. I would have approached the problem differently but your solution is much more polished than your other videos. I watch your videos to my toddler, so we can discuss your approach and introduce him to STEM. Kudos on the design work, I am sure people would be interested in both of those as products. Great job, keep it up!

The "spring ring" is an absolutely amazing idea and could literally end up being like the next big thing. I can see people lining up to buy this. Im already in love with it and i want one.

I signed up I can't wait for it to come😊

The shield toy sounds great

1:11 yes, actually in the comics, a hidden power is that he can calculate anything like 10x faster than the regular brain.

The spring ring is gonna get you so much money, I'd actually get that.

I would buy one of those spring ring things!

the fight was epic

If I’m not mistaken, the reason the shield moves the way it does is due to cap’s enhanced perception from the super soldier syrum. He basically calculates the trajectory super fast.

Your work is super nice and good,😃🤩💕

They actually already make a bouncing disc like this. The center is made out of cloth and the outer ring is a tube and it bounces off walls quite well. The one I have is about 3 ft in diameter

I’d definitely buy a “spring ring”

That is actually really cool.

You’re so good at weapons, you should make an online weapon store

It’s funny because Cap really is just great at geometry and has excellent battlefield awareness. Canonically, he evaluates the positions of all allies and enemies and finds the best path to do the most damage without hitting his friends. He even makes mistakes sometimes and has to make big dives to catch the shield or he just misses it all together. Though that’s rare

fun fact, Captain America is actually a geometry wiz, in the comics he explains that he calculates the perfect angle to throw the shield so it always comes back to him

Really cool

Awesome job. I just imagine SR chasing his shield around, getting it stuck on roofs and trees now lol

Never tought that the most realistic way to make Cap's Shield functions would also be the safest, hahahah

Cap actually is a master in geometry in the comics so that’s why he knows

I love Spidey's comment in civil war. Also, give me one of these shields NOW!

Good job

In the comics, its actually one of caps abilities to calculate the perfect shots in a split second. One of his powers is hes just... Really good at math.

so we just gone ignore that crazy boomerang shot that they did in slow motion...??

No cap. This dude is an actual Genius

Please mass produce these! We will buy them!!

Now THIS is a good one! For these high-traffic projects that have been attempted a lot, it seems like sometimes a fresh, simple, creative approach is the key. Love the VFX drone boomerang shot too.

This is actually insane jake those bounce discs themselves are dope, I’d definitely buy one!

YO THE FRISBEE PROTOTYPE IS EPPPPIIIIIICCCC!!!

Yes

The fact that this is just so simple is mind blowing!

This shield is awesome! It's cooler than the shield we used for our Captain America fight scene breakdown.

OMG I WANT ONE OF THE FIBERGLASS FRISBEE!!!
