“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!

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

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!

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

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

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

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

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

That collab with Allen was so fire

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

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

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.

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!

Jlaser videos you're MY favorite youtuber

yes the spring ring is awesome

The rivalry with Allen Pan made this so much better LMAO

"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..

Well done jlazer 4 making that🎉

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

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.

your explanation is like a physics teacher

Thank you for you building Captain America suit !

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

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

Insane project dude. Keep going

whoa you are like the greatest inventor i have ever seen

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

Dude, that prototype could revolutionize ultimate frisbee

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

You never cease to impress😊

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

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

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

Oh my god, this is AMAZING

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

“ 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

wow what a video. especially loved that ending

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

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

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.

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

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

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

amazing project

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

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.

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 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

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

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.

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

10/10 amn good job it worked so well.

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

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

Epic bounce!

Amazing! Great work! 👏

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

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.

Such a cool design

Spring ring is a good name. Also, I would love that

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

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.

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

Please mass produce these! We will buy them!!

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.

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 would buy one of those spring ring things!

No cap. This dude is an actual Genius

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

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.

Amazing work!

Your work is super nice and good,😃🤩💕

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

WHAT IS THAT TRANSITION THAT IS CRAZY AFTER U MADE IT

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

I’d definitely buy a “spring ring”

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

The battle at the end was pretty good

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

In marvel lore (and I think even in canon) vibranium is actually the most elastic metal on the planet, on top of being ridiculously strong. The combination makes it nearly indestructible. Cap’s shield is a combination of that alloyed with proto adamantium, which is just the hardest substance known to man. The combination makes for a good shield that also bounces like crazy

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

the fight was epic

This shield is amazing i love it you sho I ld make a metal one next just a sugestion

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

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

You've been great at making all these creative stuff. You know, I could help you build things with my mind like an electric glove that gives you superpowers and a headband which makes your wishes come back to life. I've been watching Disney plus for a whole decade. I've been looking up to you my whole life. This is my chance to make thinks real. So, let me Just say one thing. You're awesome guys! You Rock!

I think If he used really strong clear fishing line and made a retracter on his hand but also made the bounce thing would be perfect cause you can click the button and get it back to your hand easily

Fun fact: the serum enhanced Cap's brain as well as his body, and he actually does do all the geometry before the throw, in the comics at least

I have never saw a bouncing shield you are awsome

Yeah that sounds so cool

Honestly he's a legend why didn't we hear more about him

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

OMG I WANT ONE OF THE FIBERGLASS FRISBEE!!!

Really cool

Fun Fact: Yes Cap is really really smart so no surprise he calculates his trajectory when throwing his shield with almost perfect timing and throw.

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.

It’s so amazing I want one right now I wish you could make 1000 for everybody right now
