I built a Bear Trap that can cut you in half 

Your browser is holding you back. Level up with Opera here: opr.as/Opera-browser-TheBackyardScientist

The level of mechanical energy you are playing with here is terrifying. You were quite brave to operate the mega trap from such a close distance lol

I was wondering why my mum kept visiting you. Makes sense now

As many times as the latch slipped, i became increasingly nervous every time he was standing in the middle of it.

“The all new Elephant trap! Only 3567$ dollars!”

When I did my hunter/trapper safety course we had an instructor that stuck his hand in a trap on purpose, it closed on his fingers, and he said with a perfectly calm look on his face "This hurts like hell, but it won't break your bones" and went on to tell a story about how he was setting one and got both his thumbs stuck in one and had to work his way free by himself (trap was staked to the ground)

Can't wait for the giant bear trap experience at next years opensauce

1:26 bro litteraly made the cleanest rap

That was a wild roller-coaster between gripping anxiety and terror, and pure awe and satisfaction

i’m sorry WHAT

I don't even trust my own software to run properly. The amount of faith he has in the safety of his own engineering is crazy to me

I love how often you stand inside the trap while it’s down, I know it’s not armed but I know you know what your doing and it’s hilarious.

i love how TheBackyardScientist puts really happy music in the backround and makes a video about something that can kill someone

It's funny how the big trap is illegal to use not because of what it would do to a bear, but what it could do to you and then he makes it even bigger.

I didn't know bear trap content was what I was missing out on. That thing is terrifying lol

I don’t like how he’s just casually walking all up in it and around it, even if it’s not set those teeth look SHARP.

That exact "beartrap" you showed at 3:00 is a reproduction model where the springs have been annealed to a level of 2.5%... Had they not been annealed, they would have maintained their 100% compression. Not to mention the fact that teeth on the jaws are fundamentally frowned upon by any true trappers & outdoorsman.. thank God they outlawed the teeth on the trap jaws Nationwide scores of years ago. That being said, badass engineering skills and you gained a subscriber 👍

I thought years ago kevin was the most lighthearted crazy scientist on RU-vid but he has quickly become the most menacing

"This trap is actually illegal to use" *continues to use it, then make one that 8000 times more powerful*

I’m not going to be surprised if you randomly stop uploading, this is stupidly dangerous, at least make a Shield I BEG

I've been scared for his safety in other videos before, but holy crap lol this one was insane. Even though the video was already published it still made me so tense. I was just waiting for the unsprung trap to start slowly closing with him inside it, or for one of those teeth to fly off completely, or for him to absolutely mangle his leg while stepping in or out of it, or for some shrapnel of whatever he was shredding to cut someone up, or for the entire machine to explode, sending metal and teeth and parts and coil springs flying everywhere, etc. etc... lol. That being said, I'm still so glad that people are out there making weird and wacky stuff like this and sharing it for the world to see. Now, thanks to TheBackyardScientist, next time I encounter a problem in my life in which building my own incredibly over-sized and over-powered bear trap is the only solution, I'll already know exactly what NOT to do in every situation!

Kevin hadn’t uploaded in so long I was starting to get worried that he’d died microwaving a microwave or something crazy like that. Turns out he was doing something arguably more dangerous, but at least he’s still okay!

I remember walking through the woods and almost stepping on a bear trap, that was a scary day. But with this one, I would just be cut in half and not have to be scared, very cool.

I wish you would’ve been a bit more honest. There’s videos of trappers putting their hands in spring traps, they don’t break bones, they done break skin, they don’t even hurt. Spring traps are designed to hold whatever’s trapped there. It’s uncomfortable but not painful. The damage you might think you’ve seen, come from animals struggling and fighting to break free with their teeth.

13:45 Mechanical devices often need lubrication!

5 months, and it was worth the wait for a giant bear trap

9:33 "a bolt just flew right by my head!" "Yeah but look at this bone though" 😂😂😂

New fear unlocked: Standing in a bear trap, unsure if it's going to go off accidentally

Dude this is so scary. I'm glad you're okay. Love your videos. Wish you could do this full-time

12:37 I f**king knew it

The fact that he keeps going even after noticing nuts and bolts flying off the teeth is insane. There’s only 2 bolts holding each tooth in place, and their trajectory is directly horizontal with the people standing around the bear trap.

i love how the last one keeps shooting nuts and bolts every single time it closes

Immagine breaking into this dudes house. Getting reeled in by an automated spear gun, getting your head trapped by a bear trap, and then getting melted by a flordia man with a crackhead lazer gun

This is by far the most terrifying thing you have made yet. I'm surprised you made it through the whole video without anyone losing body part.

I love how casually he just stands in the middle of these literal jaws of death while trying to see how mangled the things, which he literally just watched the bear trap absolutely obliterate, fully were.

You need to upload more video's man! I am happy everytime a see a video.

I didn't know I needed this video. Well done!

That gleeful “it cut it in half! It cut it in half!” at 13:51 is so pure and beautiful 😭

You know that level of safety measures would never pass on mythbusters. You are insane to have done what you did.

I love the William cameos in Kevin's videos and the Kevin cameos in William's

This is something that you would expect to find in monster hunter for things like elder dragons

Well done Kevin!

1:25 My man starts spitting bars!!! 🔥 🔥 🔥

7:48 casually looking in death’s face

Gotta say, I feel like I deserve at least a little bit of credit for this build, considering how much my mom helped you out with it.

If I read his titles in my notification, I just say *"Of course you did."*

I know the springs are relaxed and have to be tensioned using the hydraulics, but every time you step into that trap as it lies flat I want to scream! That old style "only for display use" trap was scary enough for me.

10:23 Yeeet 😆 🤣

bro went from making green fire in 3d (his first video) to making a bear trap that can cut you in half

How is no one talking about how absurdly hilarious the Rat gun is??

You should totally test this with one of those ballistic gel dolls that have fake organs and bones in them. I'm really curious to how brutal that would be.

12:05 So you just made reusable and undigestible Mentos.

Thx for the tutorial

The "your mom" joke when making the jaws made me laugh so hard and so loud! This is why I love this channel! My fellow Florida man never disappoints!

"I made a giant bear trap that I partly arm by putting my arm inside of it." Never change.

0:08 bro risked his life putting pressure on the big boy

You just know its gonna be a good backyard scientist video when he's done building the giant murder machine before the halfway mark

The 'your mom' joke was despicably flawless 😂

14:09 that is the look of him realizing what would have happened to him if the trap went off any of the times he was inside of it

Honestly out of all these videos this one had me the most nervous for you guys. Especially with the electricity from the TV. I always tell myself tho. It wouldn’t be uploaded if something happened ❤️🤷🏻‍♀️ stay safe ❤️❤️❤️

i love that this has attracted all the insane engineers and scientists of youtube

I would also like to add that alot of modern animal traps are designed to not harm but only trap an animal walking on it. These specialty ones and real old ones are scary dangerous.

Kevin's truck being full of bear traps in William's plane video makes a lot more sense now. I mean it wasn't really unexpected then, but at least now there's a reason lol.

Wow. That's impressive, and scary. Impressively scary. Good job!

For those who don't know, the reason you don't want to fully cut off blood circulation is so the racoon or other animal doesn't try to chew on their leg which causes pain and makes it messier. (NOTE: The leg chewing is by instinct, they don't want to do it, but they still do it anyway because they attempt to escape by instinct.) I went through a hands on trapping course that actually lets you dispatch, trapping term for kill, the animal yourself. And they allow kids.

william standing menacingly in the right corner 9:59

I’m starting to realize why I am getting a mechanical engineering technology degree. It’s because of guys like back yard scientist, Micheal reeves Willy osman, styro pyro, etc. The ability to create such chaotic neutrals through engineering is the kind of thing that really scratches my brain. I remember watching these guys as a kid/ teenager and wanting to be just like them lol.

The landscaping is just so beautiful at 0:55 ;)

Definitely want to see this in a movie now

The ballistics gel test would have been better with a partial skeleton included. I learned this from MythBusters. I'm guessing it's a lot trickier to construct, though... keeping the bones in place while adding the gel... but I know far less about ballistics gel than I do about bear traps, thanks to growing up as the son of a hunter and trapper.

5:41 your m-

I like all of the stuff you do!

Idea: Make a rocket powered door closer (Added info in case you don't get it: Those door closers that like close in a fire, to make one of them using a rocket and maybe use like a tripwire or sensors to activate it)

13:03 you can see sparks coming off the teeth as it scrapes the toilet

it's insane to me that he went through all that fabrication, and his choice of activation method is throwing LOGS and BRICKS at it 😂😂😂 his goals are beyond my understanding.

the way he feels perfectly comfortable standing in the jaws like, even when it's not set that's still TERRIFYING 💀💀

Opera is nice except for a few things. 1. Instead of Google harvesting data, it is China 2. You can't import bookmarks and logins from another browser 3. Extensions don't sync, so every time you get a new device you have to re add your extensions.

My uncle lived in Alaska for decades and was an avid hunter. He drove to Missouri once just for fun. He brought some fun toys for us. Left a real bear trap with jaws just like on TV. They had been outlawed in Alaska. Everyone thought it was cool as hell till it cut a broom handle in half. And then a hammer handle. My dad hid that thing somewhere and ony HE knew. My brother's an I looked for it for years. My dad was pretty smart... lol

Every time he triggers that trap, an insurance adjustor somewhere snaps awake and says "Something is very wrong!"

2:04 that scared me and closed my right eye only once also the same thing scared me once, now I get so used to it I don’t get scared or close any eye

Was not ready for the mom sitting joke. Brutal. lol!!!!!

I love how the trap is so powerful that pieces of it fly off every time it closes.

I’m no expert, but watching you do this with no shield at all was truly terrifying. Please take care of yourself, it would be awful if anyone got hurt. (But awesome video and channel overall, nonetheless)

the your mom jokes were the cherry on top of this awesome video haha

this video cured my depression

This content is why I subscribed 6 years ago on my honeymoon. Unlike my marriage, Kevin still brings me joy.

3:20 didn’t have to do us like that man

i missed you guyses uploads maannnnn

12:13 i guess you can say they went "pop"

Correction: balistics gel is supposed to mimic how soft body tissue reacts to BULLETS specifically. They aren't rated as a human analogue in any other use case, and in reality, while it does provide a good baseline, it isn't even always a good human analogue for gunshot wounds. (Any number of issues arise, mostly that you need different gel for subsonic vs supersonic rounds- and sometimes just for different bullet speeds regardless -different bullet types, and even different sizes. Though usually the biggest issue is how the speed changes things.) To be clear, it's totally fine to use it, people just ignore that it's for ballistics use specifically rather than general stuff like cuts and blunt force a bit too often and it should get mentioned more that it doesn't really do a good job representing how a human body would respond in the majority of situations.

Imagine being a thief and walking into a trap that does this to you

8:30 how dare you, why lifeline?

the fact this guy keeps standing in the bear trap even after knowing it can go off by itself is insane

I mean this with concern, please get some ballistic glass shields. You can even put them on wheels. I like this channel. It only takes one accident to permanently change your life.

5:24 I think the massive neck wound from the spear makes the bear trap irrelevant.

I like how some bolts and washers flying off everytime the trap closes

Nice job but the amount of force so close is terrifying 😮

Man one of those spikes could have gone off if you didnt notice any bolts fly off, it was making me so nervous lmao. With you and everyone right in the direction they would fly off

You know it's scary when William Osman is cowering half a yards length away. 10:09

I love the person's reaction to you saying the pumkin costed 70 dolars
