How a Tranquilizer Dart Works in Slow Motion - The Slow Mo Guys

Hi, I'm Gav, I'm Dan, we're the

slow

motion

guys

in the old garage because it's winter and it's wet and cold outside. Yes, let's do something in the comfort of the interior. I really like the videos where we learn how to do it. something

works

in

slow

motion

usually something you just take for granted yes you take it for granted that's exactly right because I didn't know how a

tranquilizer

dart

works

this is a

tranquilizer

point there's a lot more to it than you think it's kind of a flying syringe that manages to use pressure to inject into the animal, yes, I'm glad I didn't know about this at school because if I did, at any moment someone would kick the back of my chair, you should say: well, my first mistake is that there was a hole in the end of the needle, but that's not where it is, it's not at all, the end is actually blocked and there's a little hole there in the front.

Can you see that yes, that's where our juice is going to go? it comes out of our drugs, our tranquilizer or whatever, and the way to prevent it from coming out right away is with this little rubber stopper that will go directly over the hole to cover it up, so we have our needle here is where we put our solution or our medications tranquilizers or whatever needs to be administered, medication, whatever and this here is an air pressure chamber and this is how we get the pressure to inject the fluids into the animal because what's going to What happens is this needle will pierce the skin of the animal and then this rubber part will not be able to go through the skin after the needle, so it will be pushed back along the needle, revealing said hole and then the air pressure at the back will be able of struggling to push the fluid through the needle and out the hole, so which medication have you chosen?

We've gone with the red food coloring, that's actually okay, yeah, it's really important that you have kind of a standard syringe here if you really want to. using real drugs you would use a medical syringe and you would put it in one of those bottles, you know, you get those bottles and then yeah, take them out and then we can put our drugs in and fill a syringe, we'll put our needle here and We can take this part off here, we have a safety cap so we don't get punctured, so this part here, this little gray thing that you might be able to see in the air chamber at the back, moves freely when there's no pressure. there what we're going to do is pressurize this rear chamber we're going to take our syringe again just fill it with air, push it in and then pressurize this rear part here I'm going to put about seven thousand pressure and something seven cc of air, so now you see that the gray thing is not moving because there is a lot of air pressure up here and that is forcing the gray thing against the edge that is not allowing air to pass through.

It is called a check valve. so it allows air to come in and not go out, the last thing is to add some sort of feather to the back, the technical term to make it look like a troll doll head, that is exactly what it looks like and this will mean that when you are blowing on the back of the

dart

, it will cause clogging and allow air pressure to build up behind it so you don't just blow around the dart. Yes, it is a fully loaded tranquilizer. Well, here we are. the area of ​​the animal this piece of synthetic leather represents the skin of the creature it is called skin if the animal is not dead uh I don't know it's alive just skin okay maybe we have a thick skin I think it's a skin Okay , depending on what it is, the light is on the back and we're pointing backwards, so we'll see the needle go by and it will represent sort of the inside of the animal, the reason we do it like that.

The way to avoid it is because this background is clean and the red juice will probably spray it everywhere, and then we'll turn around and get this angle. We should probably also mention not to try this at home. This is dangerous. Oh, I didn't do it. Pretty strong, that was pathetic, no, you have to give him more beans. I'll recharge it. I see you've got your little extension rod on trying to get all the power out of it. Maybe I just have very weak lungs, well you do. a little bit of a cough right now maybe I should cough and it will fly out oh that one worked God went straight through okay before we look at that back let's take a picture of this side okay then I can.

Cut them together so we can see everything for the first time, but up here like in this area, do it oh, it's perfect, yeah, I think that was pretty cool, oh, I got it there, right? Actually, it is a fairly concentrated current, yes. Isn't that a pretty abstract look? Yes, quickly, isn't it? It really is likely to stay there, that is, 40 times. It's happening. I really realize that we are in Sloane. It's very forceful too, isn't it? I guess because if the the animal is moving or you know, if it's an active animal, they want to get it injected as quickly as possible so it doesn't have a chance to leave it, or yeah, and it's also just a factor of the fact that it's a fairly wide cylinder that holds the liquid which is forced through the thinnest needle and smallest hole, even a small amount of force would just force it out for miles, that's a good point ok so next I think we should move closer to the back, maybe try blue.

Well, I'm going for a different color, this is medicine, this time medicine, okay, I'll be behind you on this perfect, so what we really want is for it to come this way, okay, because now I've lowered the frame rate . I've decreased the width, I've decreased the height because I mean a lot of the top and bottom of the frame is not used, we're just getting that long projector like we do with the bullets, so we're at 3000 frames per second now at 720 around here. a much more shallow turn, okay, it might take a few tries, okay, to be honest, oh that was it, you did it, there you go, you just listen a little like you could do it from really close if you want, it's well, oh, perfectly, in fact, geez, look. to me straight oh the lens there's no white fast white I need a wet wipe are you trying to put a permanent blue filter on the lens is my color I'm blowing some kind of deadly trumpet deadly bagpipe yeah, yeah, it's like a bullfrog oh, like a hamster, like a puffer fish, like some kind of chubby hamster.

I could think of other situations where you would make that face, it was a bit of spit, yes, and the aim, the focus was supreme, well, thank you, yes, oh. It's a good approach, right? Yeah it was probably an inch, turn an egg, that's not how fast it is, it's 3000 frames per second which is fast honestly we could have done it with the faster camera on this one so it's about 150. foot per second, so it wouldn't surprise me at all, so at first it throws the liquid forward because it has a smaller slit to get through and then it's like yeah, I think the little pause in it was probably the deceleration, maybe. the liquid swayed back slightly because remember the pressure here, maybe any pull will push it back through the needle so any kind of wibblemen can pause it for a second, but look how much you got that focus, oh actually, that It was perfect, it was perfect.

You can see how quickly it gets blurry, like it's a centimeter away and it's already going out of focus, the kind of hole is almost out of focus, like the end of the needle is almost out of focus, yeah, oh wait. no, it's because it's coming towards the camera, yes, it's coming towards the camera, oh, now what I've noticed is that I thought it was quite interesting, let me change this to frame by frame mode, okay, now look at a little bit of blur, yeah, to 3000 frames per day. second on a 90 degree shutter oh god look at the plug so it hits and starts sliding but because it's like rubber it bounced back faster so it doesn't just like to be pushed and slide , it bounces hard back and then the rest of the needle hits it like a hammer straight back, oh, and then it crushes it, so it's like, oh my god, we only realized that because now we're at 3,000 in instead of 1,000. just when you first showed it to me in real time, yeah, I saw something was I thought of that rubber stopper, I wasn't sure what it was, then you explained it to me frame by frame and now I can see it clearly like the day, yes, but I saw that something was happening with that, what happened there.

I like that in this. shot behind your blowgun you can see the bigger blowgun so actually you could use it on a dinosaur or something if need be that's the t-rex yeah yeah but you have to set it up for ages and then wait . to get the t-rex through, we could probably modify that to shoot this, no, absolutely, if you wanted your tranquilizer dart to come out the other side of the animal, okay, now we have a nice white balloon with just water in it, no coloring . water and I guess this will represent some kind of blood system behind the skin if an animal had a big lump of blood, so if its heart was on its back, yeah, hopefully the rubber will move away and we'll be able to see. the color what is blue yeah blue blue injecting into the water before it falls okay so you just have to hit it over here okay go ahead oh god you definitely got it I got it there will ever be a time when I don't let's do it.

We don't destroy our small high definition monitors. Have you seen our videos? Oh God, that's coming out. It's surprising we don't destroy more things. Everything is stuck on the serial number. I will never be able to record this now. I wonder if there are pictures of water inside. the balloon in the air I wonder how fast the balloon will burst compared to the damn box yeah but the rubber will be oh can you see it flew out the side of the balloon that's exactly the shot I wanted flips an egg there are some like drops pure blue color more falling there oh yeah I really stuck the lens there oh look it's like catching some of that you see the water from the dash goes through the blue stream and catches it so we're paint paint the blue background in the air is that it could be a video where we just throw water drops like a blue that bursts of different colors and they will pass and become multicolored drops, I think so.

That would be wicked, that one's for the future, well we figure I'll forget about the logistics of that one. Yes, next I'm going to test our probe lens. There is no pressure on this one, you just have to hit it within half a millimeter b. you know you're talking to sorry, I don't even know why I doubt that, it's good, oh, not bad, that's not bad at all, that's pretty good, a lot of negative space, but I mean, we're talking about millimeters here and the um, the liquid is also rising, yeah, towards the ceiling, that's perfect, oh damn, what a ball, I love making videos like that, what will you learn something?

Yeah, you learn something and the slow motion looks really cool, really satisfying. I also like to use the punch. gun, to be fair, yes, I think I could become a veterinarian. Okay, I should warn you, although not everything about being a veterinarian involves using a blowgun, in fact, very little in very specific places, would you really use the blogger? Okay, I'm coming. to specify that if I can use the blowgun, okay, just get the gorilla, someone else, someone else takes care of that, yeah, yeah, my job is done, why do we pay that guy? I also like how that kind of water comes out of the thing. when you brush well yeah it's still pressurized I forgot so I thought I totally forgot I had done it oh it all came out it went in my eye man I got medicine in my eye wait what good look, Tony didn't expect That I forgot too, I pressurized it well while Dan cleans himself.

Make sure you subscribe. He presses the old bell, our favorite bell and we have a second channel too. Thanks for watching. Did any of them touch me? I think so.
