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

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

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

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

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.

1:26 bro litteraly made the cleanest rap

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

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.

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

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

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

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

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

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.

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 thought years ago kevin was the most lighthearted crazy scientist on KZfaq but he has quickly become the most menacing

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 👍

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

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’m sorry WHAT

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

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!

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

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

13:45 Mechanical devices often need lubrication!

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 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.

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.

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.

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

"The soda was too easy, so now we're gonna try toilet" That's a first for a sentence

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

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

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

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

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

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.

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

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

When it comes to this guy and danger, they are the best duo.

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.

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

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

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

Well done Kevin!

The 'your mom' joke was despicably flawless 😂

This thing is terrifying. It would cut an adult human in half

7:48 casually looking in death’s face

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.

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

I know this video isnt the best example, but, This channel makes me think about what kind of videos we would have gotten if Bob Lazar had youtube when he was doing things like making his rocket car and driving around town

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.

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

the military is gonna want this guy for building traps and stuff like these

I'm quite surprised that my mum was so helpful in this video.

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.

william standing menacingly in the right corner 9:59

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

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

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

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

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

this video cured my depression

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.

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)

One day this man is going to snap and turn into Jigsaw-style serial killer.

I like how the soccer ball got launched. It almost bounced off of the palm tree!

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.

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

The freaking _SPARKS_ flying off the teeth when it cuts him in half was SICK!!! (>◡

9:33 "one of the bolts fell out" Osha:😶😠😡

Ah yes, i love it when kevin creates devices that are definitely war crimes

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

It can cut through cinder blocks, it’s the perfect home invasion tool

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

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

5:41 your m-

2:07 the soda explosion jump scared me 😂

Rent that thing out for all kinds of fun! (But make sure to have a lawyer include an airtight waiver in the rental contract).

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

"I'm worried about flying shrapnel...so anyway here we go!" You absolute mad man ♥

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

Imagine having a bear trap thrown at u like a pokeball lol

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

Glad Kevin is still alive and provides us with hilarious content!

This is something Jigsaw would build to punish a poacher.

10:23 Yeeet 😆 🤣

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.

Finally he’s back, Can’t we all agree we missed him!😂

Bro made the neck springlock 6:26

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

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

Love all your videos, this one was legitimately scary to watch though.

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