Sharks Attack GoPros? The Truth
51sThe dramatic refusal to swim with sharks and subsequent experiment creates high tension and curiosity about whether GoPros attract sharks.
▶ Play Clip"Delivers on the GoPro vs shark premise but expands into broader Shark Week content, making it slightly oversold."
In this Shark Week episode, Mark and Noah test shark myths including whether GoPro cameras attract sharks, use a chum torpedo from a submarine, and explore bioluminescence. They also investigate the Bermuda Triangle's supposed curse with statistical data.
Mark and Luke Tipple test if sharks are attracted to the electrical fields from GoPro cameras by using a powered GoPro vs an empty housing. The powered GoPro gets more bumps, suggesting validity to the theory.
Sharks have ampullae of Lorenzini that detect electrical signals, allowing them to sense prey's heartbeat from up to a few meters away.
Mark unveils a rig with multiple GoPros and a chum torpedo to attract sharks in a frenzy, testing the effectiveness of the torpedo design.
The GoPro attraction myth is busted (sharks attack due to electrical field not because it looks like food). They then use a super chum smoothie to attract sharks, which works, causing a 'sharknado'.
Noah and Mark visit a wrecked ship area to investigate the legend of a ghostly 'Gray Lady', but find nothing conclusive.
Mark shows bioluminescent algae (BioLume) that glows when agitated, and they test if sharks can see it in the dark.
They descend in a submarine to 600 feet, fire a chum torpedo, and attract a large group of sharks, including a great hammerhead, confirming the torpedo's success.
They swim at night with bioluminescent algae, encountering sharks. The experience is terrifying but successful, with no attacks.
Statistical analysis shows that the Bermuda Triangle has more plane and boat crashes simply because it's a high-traffic area, not due to curses. Insurance companies don't charge higher premiums.
The Bermuda Triangle's danger is statistically explained by heavy traffic, not supernatural forces. The experiments confirm that sharks are attracted to electrical fields but are not inherently aggressive towards humans in these controlled conditions.
What is the ampullae of Lorenzini?
Sensory organs on sharks that detect electrical fields, allowing them to sense prey's heartbeat.
03:37
Did the GoPro electrical field attract sharks?
Yes, the powered GoPro got more bumps than the empty housing, confirming the theory.
05:05
What was the 'super chum smoothie' used for?
To attract sharks in a frenzy after the GoPro myth test was completed.
07:48
How many GoPros were in the rig for the chum torpedo?
21 running GoPros.
07:22
What is the 'Gray Lady' legend?
A ghostly spirit moaning at night for her son at a shipwreck site.
09:44
What causes bioluminescence in the ocean?
A chemical reaction in certain algae that produces light when agitated.
11:34
How deep did the submarine dive?

12:31
Why does the Bermuda Triangle have more crashes?
Because it is a heavily trafficked area, not due to supernatural causes.
21:41

19:51Bermuda Triangle curse debunked
Uses statistical data and insurance premiums to logically disprove a popular myth.
21:25[00:00] in the middle of the ocean at night, mesmerizing bioluminescence we captured But unfortunately for us, the sharks agreed.
[00:14] in a precarious situation risking my life for science. because for Shark Week this year Now, in the past to celebrate Shark Week,
[00:27] can sharks really smell a drop for human blood over fish blood? to potentially debunk a few more shark myths.
[00:43] dangerously close to sharks in the shallows, And we're even gonna take a critical look into There's a legend on this here island.
[00:58] - But of course to do that, I'll need an expert from Stranger Things. - And so before I head to the Bermuda Triangle
[01:10] for the first time, in an effort to make him feel more comfortable, I'm gonna harness my inner Hopper. (upbeat music)
[01:26] my marine biologist shark expert buddy, Luke Tipple. We learned a lot last year, I feel like. What kind of noises I make when my life's in grave danger?
[01:40] we decided we wanna get him right out and to test our first potential myth, (upbeat music)
[02:01] - No. There's no way we're swimming with that. - Bonkers, right? - Oh my God.
[02:13] No, no, no, there's no way. (water gurgles) (Noah yells and Mark laughs) - And so while Noah reconsidered his life choices,
[02:27] we have these like 360 cams on a stick, Like a number of times, they would bite at it, right? on a dive, like in Hawaii, they'll actually
[02:40] because they say the sharks are attracted to, like, the electromagnetic waves and it feels like, eh. - According to Luke, he's definitely seen sharks
[02:52] you're shoving the stick way out in front of their face, from the GoPro that got them excited. We prove that they love the electric fields,
[03:07] We would dive down and Luke would be holding a selfie stick And then as a control, I would be with an identical GoPro housing, but it would be empty.
[03:22] the tiny electrical field coming from the filming GoPro. each of our selfie sticks got bumped or attacked. there is some validity to the theory here.
[03:37] for 450 million years is because they detect we do, but with two bonus senses as well. in the water in all directions around them at all times.
[03:54] That's what all these little dots under here are for. it gives off an electrical signal. So sharks can sense a fish using its muscles
[04:08] simply because of its beating heart. first ocean scuba dive experience - [Noah] Oh my God, there's so many.
[04:23] - [Luke] We have about 20 Caribbean reef sharks here, - [Noah] This is unreal. and started the experiment.
[04:37] scoping us out for a bit, after which - [Luke] Okay, we got one hit on the camera. There's a second hit on the camera.
[04:52] - [Mark] So after about 10 minutes, Oh gosh, oh gosh, right by my face. there were definitely no attacks yet.
[05:05] Yeah, that's the scariest part, right? I don't know - Yeah, and at - They swim right past me and they're like eyeing me.
[05:17] - (laughs) Yeah, don't look them in the eye. while my empty camera case was only bumped once, that sharks will attack GoPros
[05:33] But lucky for us, I had a backup plan I've got something over here I wanna show you guys. duh, duh, dun.
[05:48] - I'm glad you asked, Luke. First of all, we've got a bunch of GoPros, and they should really go crazy for this, right?
[06:02] But the second purpose for this rig this is a waterproof version of that fancy Now, two years ago I came up with a poor man's version
[06:16] of this by sticking a 360 camera to the end of a harpoon, But we tested this new and improved rig for this version, because we were able to
[06:28] Now, Caribbean reef sharks are pack hunters, the most dangerous sharks in the Bermuda Triangle, And so my hope was, the sharks would in fact
[06:41] to the point that it was a frenzy. underwater, you know, - Oh! for what might lie ahead, it was time
[06:54] I gotta pee, and luckily two years ago I'll be fixing that situation in about five minutes (Mark splashes loudly)
[07:08] - Yeah, the rig! follow-up experiment, we took the opportunity to capture some bullet time shots as well.
[07:22] in a rig with 21 running GoPros, will attack a GoPro thinking it's food was busted. that electrical field, which is why
[07:35] It's just that it would be such a different for hundreds of millions of years to consider food. next time you find yourself surrounded by sharks.
[07:48] and a busted myth, what we didn't have was But luckily I had another backup plan, to my secret recipe from last year, the super chum smoothie.
[08:03] sharks love this stuff. with the super chum and then drop it overboard, And now since our experiment had concluded down below,
[08:18] We got the sharknado. Coming in hot. Oh, it's coming down fast! (laughs)
[08:35] They're definitely agitated, Oh, they're really going for it now. Sharknado!
[08:51] - [Luke] One of the sharks just bit to your right. I think our smoothies worked. double the amount of sharks now?
[09:04] I want you back, back, back! - [Mark] Ooh, they love it. I think we better hit the boat.
[09:17] - [Mark] Okay. and even another dive later where Andy captured this footage of a super rare great hammerhead, Noah innocently inquired
[09:30] We should ask if we could explore it. - It was brought here in 1952, There was a ship that wrecked here,
[09:44] This five year old. But they said that you see a spirit here moaning at night for her son, you know?
[09:58] - So, I mean it's called the Great Isaacs - Of course they do. (laughs) - Yeah, we should.
[10:12] (Mark laughs) - No problem. - [Noah] Let's get to it. it would be a good chance to gather some firsthand evidence
[10:25] Dude, I thought that was the gray lady. for this place was legitimately creepy. To see that, you gotta get Discovery Plus,
[10:39] like my show with Shaq and Dude Perfect. based off the glitter bombs. for free for seven days, and after that,
[10:52] as to whether or not the Bermuda Triangle itself was cursed. the gray lady would wear, too. until I could do a bit more research myself.
[11:06] I've ever seen by a factor of four, It was a long day and we needed to get some rest, real fancy snow globe submarines and descend way down
[11:21] And to do that, I had a few more tricks up my sleeve. Now it doesn't look all that impressive like this, something remarkable happens.
[11:34] chemical reaction that occurs in nature It's totally non-toxic and natural I mean, how cool is this?
[11:46] the sharks can see this stuff because it's commonly said That each one of their senses has a different range. are effective to hunt prey in about this range.
[12:02] on their sense of smell for something like blood But allegedly they rely quite a bit And they can see as far as a football field in length.
[12:16] their night vision is 10 times better than us humans, with this glowing stuff in darker conditions. but with a catch, because you can't exactly
[12:31] when you're 600 feet underwater. about what you can attach to the outside So, we handcrafted this beauty.
[12:45] we could fire from the sub. and this middle section is balsa wood, because that's where the super chum is contained
[12:57] And as you can see from our last minute pool testing, to pull this lever, which would allow forcing the torpedo out, opening the bag of super chum
[13:09] only traveling a short distance, So with our final test looking pretty good, for both of our first ever dives in a bonafide submarine.
[13:22] Which one's mine? - [Noah] Oh my God. - [Mark] Look at this. (dramatic music)
[13:37] (seagulls squawk) - Top Side, Nemo, please dive.
[13:50] (dramatic music) (peaceful piano music)
[14:08] You ready to go on a 270? - Okay, Nomad, I'm ready when you are. (peaceful piano music)
[14:24] - We're gonna go deep, man. We are approaching the edge of the wall. like the Grand Canyon, and we were going over it.
[14:40] you could see signs of where a coastline used to be And he said everywhere he dives around the world, And the deeper we went, the darker it got.
[14:56] - Yeah, let's settle down here. I'll let you drive this. - Oh, wow.
[15:10] Nice! Look at that glow. We are ready to fire the torpedo.
[15:25] - [Nomad Operator] We are attempting now. We launched it! (laughs) - Woohoo! (laughs) Ooh. (laughs)
[15:41] - [Mark] And with a bit of an assist, And now the sharks just come swimming. (suspenseful music)
[15:58] we were almost certainly the first explore this exact spot on planet earth. Oh, the fish are coming.
[16:13] The fish love it. Whoa, whoa! (laughs)
[16:25] (peaceful music) some sharks lurking in the shadows, So, we decided to try our luck at a different spot
[16:38] a bit higher up the wall with our remaining two torpedoes. (dramatic music)
[16:54] - Way out in the distance. - [Mark] And here we hit jackpot. - [Nemo Operator] Whoa, look at 'em all.
[17:06] That's terrifying. He's right on it. Holy cow.
[17:21] Look at that. Chumpedo worked flawlessly. And so with mission accomplished and our air running low,
[17:36] The BioLume was just so cool, but admittedly, the chum torpedo at the same time. will be able to see it with their night vision
[17:49] that meant we had to get in the ocean I make a point of not swimming in the ocean at night. by sharks. - Right.
[18:03] - That's a good rule of thumb. it would be my family, when they saw my ability to make poor choices.
[18:15] - [Mark] Okay Noah, here we go baby. All right, buddy, you ready? - [Mark] Okay, we need the bottle of stuff.
[18:29] (dramatic music) Oh, that's cool, dude! That's like X-Men.
[18:43] I think you guys can throw a bunch on top. That's crazy.
[18:55] That's cool. - [Mark] This seems pretty cool,
[19:07] with no lights. Super not okay with this. Now, let's try it like this.
[19:26] With no lights on. This is the trippiest thing I've ever seen, man.
[19:38] (suspenseful music) All right. All right, we got blue.
[19:51] A shark just swam by. Oh my God. (Mark screams)
[20:03] in this chain link fence all the- - [Noah] This is the scariest thing I've ever done. (Mark screams)
[20:17] (Mark screams) - Another, oh my God! (dramatic music)
[20:31] Holy crap. (laughs) Oh. that was the scariest thing
[20:46] That was unreal. like, I thought they were trying to eat us. - it can't get scarier than that.
[20:59] we flipped the lights on, there's was bunch of sharks, so. (crew members clap) - Nicely done! - Once again, it was an incredible experience
[21:11] and as a bonus, I survived. Is the Bermuda Triangle really cursed? of thousands of boats and planes?
[21:25] trying to unravel the mystery. I was shocked to discover that significantly But, there's a catch.
[21:41] and take a snapshot of all the planes in the air Now keep in mind, this region here is the Bermuda Triangle. Way more boats and planes crash there,
[21:54] It's in the middle of some of the most heavily It's like how California is the state with not because there's some supernatural
[22:07] Statistically speaking, the Bermuda Triangle or plane than anywhere else. by checking if insurance companies charge any more
[22:19] And it turns out, they don't. our first mate, Andre, had a way chipped away at my resolve just a little bit.
[22:34] running through and up to this day, Bermuda Triangle, guys. You never know.
[22:46] (upbeat music) (Mark screams) (snowballs thump)
