- I eventually got the bottles back and was able to try again farther down the channel.
Instead of mighty currents and terrible undertow, I found ... nothing?
Where did the current go?
It is, presumably, deep, along with anything caught in it.
And there goes the entire UK science budget for the year.
Re recoup some of it by selling the bottles to farmers in Arizona, who shoot them in their fields to get the water out, post video of it on youtube and auction the remains.
Sad but True!
🤣
@@Sableagle That is illegal.
We had to rob the budget for tea bags......
Will someone for the love of god get a 45kg dummy,put a life jacket on it and chuck it down the waterfall .
Yeah. For all the talk about being sucked straight down, I've seen zero evidence.
@@roganmorrow if you put a river on its side as long as its deep then the current on the top won't be that strong it will be the same river just on its side .There is a video of a man canoeing it during flooding ,he was fine.I don't want anyone to go and try any thing and die ,can't someone buy a cheap life jacket second hand and put a manakin in it and chuck it in.If someone wants to meet me there I will purchase a life jacket and something to go in it.I just don't wanna go up there on my own and look life a weirdo
@@richardatkins868 I have seen that video. He is only at the mouth of the strid and not where it yet narrows. Also the current is about 5 feet under the surface on a normal day, and during flooding that current is 5 feet + how much flooding there is. There is NO WAY those jugs even went near 5 feet under to hit the grab of the current, but if you went in as a human your feet and legs would come in contact with the current and you would be pulled under. It is basic physics, and a river on its side moves MUCH MUCH quicker due to the same amount of water flowing through a more narrow passage, like putting your finger over a hose causes the water to spray out much much quicker.
@@gundamgunpla4685 exactly, on top of that it's not a straight channel but it's great amounts of water being forced through coarse and irregular rock so the amount of turbulent flow is unthinkable.
The reason there's "no proof" in videoform is a) bc videos of people falling to their inevitable death are not well received on youtube and b) bc chucking a manequin in would be considered pollution and using a stunt dummy would be expensive and simply not worth the effort to confirm what's already known.
Furthermore why tf would anyone fall in wearing a life jacket? There's hardly any reason to already wear a lifejacket when you arrive there, as most tourists do.
They should also attach a gps to it
So many scientists in the comments here who could’ve done it better. This poor fellow is the only one who’s ever bothered to try to test the claims about this river to satisfy CZcams’s curiosity, and this is his reward.
This is just plain stupidity, honestly.
@@drewberry5737 im confused what did he do wrong
@@drewberry5737 did you ride the special bus growing up? Short bus? You lack emotional intelligence.
Couldn't have said it better Adam. Love this man for doing this.
He’s braver than me. If I knew a body of water was instant death I would not be within arms reach of it for any reason.
I wish we could dam this river off temporarily to see what was underneath
Finally someone with a great idea!
Just rock and people's crazy unjustified fantasy stories.
@@Bow-to-the-absurd and deformed fresh human face corpses
i have a feeling if they dam it nothing will happen maybe cuz beneath theres numerous caves which are pumping water to fill into the ravine already, and all the river is doing rn is flowing ontop of it going inside and running out into other random underwater exits so its a constant body of water even without the river flow ??
Yeah then flood all the local villagers and towns 😂
Why doesn’t a local geophysicist service perform an acoustic or seismic exploration? 3D picture plus known volumes of liquid would give a good model of what’s going on there
Probably the UK government doesn't want us to know that it may not be as big as it seems. This is a big tourist attraction and brings in money for the UK. Sure, it may be a 30+ feet deep canyon of limestone in the Strid portion. I can believe that. The USA has a similar canyon that isn't limestone. Antelope Canyon. There are other similar limestone canyons around the world. But are there massive caves underneath each side overhang? I can't believe them to be too large or the overhangs would have at least partially collapsed by now. Everywhere you stand, that's tons and tons of rock. The same reason why Loch Ness wants us to believe in a huge monster...and why here in the USA people want to believe in Bigfoot.
Rivers are deceptive. Even as a kid in the early 1960's my dad was warning about staying out of rivers due to unseen holes and washouts. That's saying something from a guy who swam in the Imjin River in Korea with Chinese on the other side. Rivers in the north-central US tend to be littered with trees or large branches to get snagged on. They are dangerous to small craft which a friend discovered when the prop hooked a tree stump and flipped his craft upside. Fortunately he's an excellent swimmer and swam out from underneath.
And worse are the nasty alligator snapping turtles who hide by obstructions or holes and strike anything coming near them. Their neck is very long and flexible but it doesn't look that way since the neck is usually inside the shell. They can put a serious hurt on you which I proved with a stick thick as a large finger. Turtle snapped in half faster than an eye blink.
There's good reasons our river banks and their surrounding flood plains contain lots of Ice Age and newer animal bones, especially bison including extinct ones. Those rivers were dangerous thousands of years ago.
@@jameshickok2349 alligator snapping turtles don't have flexible necks at all
@@neo-filthyfrank1347 LOL LOL Wanna bet??
@@jameshickok2349 Yes. They barely have necks at all. Stop pretending like you know what you're talking about.
That river is straight out of Lord of the Rings. Probably best to just leave it alone.
I love that this is in two whole parts to get to no conclusion. Yet somehow it’s still satisfying! Keeping the mystery alive…
somehow i’m even more terrified of this watery death trap. thank u for not falling in
Keep doing what you’re doing man these comments are just salty cause you have access to a dope river😩
We want answers.
@@livinglifeleona you have questions? We got answers
@@eddiew2325 well you need to first have a question in mind which you wish to know the answer to before you can do anything. What was he trying to test? How was this method supposed to test it? Tbh, all I saw was a guy playing with milk jugs tied to a rope in a very dangerous river. I am absolutely jealous he loves near this and I don’t. However, if I did live near this river I would attempt to measure it more accurately and logically than him.
@@someguy1688Nothing beats personal experience. May I suggest you jump in and then tell us about it afterwards.
The plastic bottles are very buoyant the high current is below the surface be extremely careful doing stuff like this
Just tie a small bucket to the line that will show you the force of the under tow in the strid. Also you can tie knots in the rope every meter and let the line slide through your fingers for 15 seconds, then times it by 4 to get a flow rate in m per minute. And finally multiply how many mpm you get by 0.0324, this will give the speed in knots.
Might have to be a lot less than 15 seconds. That pull was fierce, and it's only a 15m rope.
Off you go then mate don't forget to record it

This creeps me out the same way sinkholes do
I once found an actual kitchen sink down a sinkhole in the Dales. The mad thing was that the hole of the sinkhole was only about a foot wide. How the hell did it get down there.
I’m gonna sub just because you’re trying to satisfy us and our curiosity. I like that.
Much respect to you sir and thank you for taking the time to show us this amazing place.
I gave you a thumbs up, because you didn't get the ropes caught around your ankles and ended up in the river?
Well done Experimentation is a learning process Keep at it. I'm trying to think of a visible bio degradable float you could toss in and not worry about hauling back, cabbages? dye them pink with something safe first? Maybe try floating a cabbage and yourself in a tub see where the water lines are on ea of you Might need to tie a small rock to the cabbage. Turmips? Squash (you can fill w concrete through a small hole to get right bouancy? Hmmm, you could string 3 pumpkins in a row to imitate a small child, add some old clothes. I'd think to avoid hanging up complex objects in falls you'll need to dump in right below. Heh, are you using a safety rope tied to you and tree so you don't go over edge? You might stash your weighted veggies at top of falls, setup a cheap cam downstream in broad flats go back to top toss in the veggies walk to bottom wait to see if anything comes out, leave cheap cam and your good camera going while you have a bite to eat read .... You could try to ck along strid but again tie yourself off so you can't' slide over edge, stick a cheap cam at end of pole use that to look down see if any veggies bobing along.
You also might try to deliberately loose items in the under tow first, like tyiing some bio degradable materials into a wad weight w rock toss in. Straw? bunch of flowers? old shirt? and use an organic twine not poly twine Maybe wrap around a stick and hang on to that less strain on hand and easy to let go if undertow is overwhelming. When you prove where there is an accessible under tow you can then use that to test veggies there. Again, tie yourself off to a tree to ensure you can't even slip over edge.
and
Try to find someone to go with you, stick up a note at church or community center - bored by Covid help me experiment Outdoors we are never near ea other. Lots of time to read. I buy lunch.
Best of luck and again, keep at it (when the spring floods subside)
You could become the 'Strid' 'Whisperer' if you tag all the down flows upflows death traps etc
These are such good ideas!
A cow
Oranges are often used for flow tests
Ok, it’s a first attempt, initial experiment. Congratulations on doing something. My suggestion would be to sling in one tethered larger ballasted bottle, and sense it’s action when under the surface. You’d feel any battering, gyrating, swirling, or entrapment. If it’s doing something unpleasant you’d know. Then you can tell us.
the most yorkshire video on youtube
Really interested to see what experiments we can do next to charter this unchartered river! Interesting experiment. Stay Safe bruh.👍
I'd love to see this done with a heavier weight and a strain gauge.
what are you actually doing?
Fishing for grandma
Wasting everyone's bandwidth?
Mount a camera on a fish. Use a robotic submersible. A turtle with a tech pack. Anything but plastic bottles with various volumes of air.
Are you 12?
@@neo-filthyfrank1347 are you 11?
Literally watching your video from Tampa Florida, and holding my breath hoping you stay safe while doing this!!!
Temporarily Damm the river above when level is low enough to see it
Apart from the fact this guy is farting around aimlessly, damming would be dangerous. In the narrow areas the Strid is to 20 feet deep. The undercuts extend over 12 feet wide, funneling currents into narrowing pipes. No-one on record of falling in (since the 1400s) has come out alive. Or intact. Potholers(who can generally be trusted be idiotic) won't try it.
@@orlaoto5794 Those records are very unreliable though or at the very least meager, just 5 or 6 people have fallen in the river (and drowned) according to those records, not exactly statistically significant. The records on those who have fallen or jumped in are simply too meager to draw any conclusions from. Hence why we could do with a modern scientific investigation of the Strid to learn more about it and its underwater caverns and chasms.
@@pieterveenders9793 True. All that is needed is a man or machine sturdy (or brave) enough to do a thorough survey.
@@orlaoto5794 czcams.com/video/MkPUPxPfFHw/video.html Watch around 3:40 mark, one of these crazy kayakers tipped over and fell in, luckily his friends managed to pull him out
@@orlaoto5794 recently measured at over 60m deep at its deepest point and regularly over 20
Conclusion. You dont test the strid the strid tests you.
If I didn't know any better, and I stumbled upon this stream, I would think it was an amazing trout Fishery
There is some great Trout fishing up and downstream of here.
All I ever wanted was to see someone do stuff with that river. Always hear the stories but no actual videos.
Can't wait for the next one! Wish I lived closer to the strid, I'd be doing the same thing!
Bruv.... Flicking you a sub purely because you used the word yeet 😅 interested in learning about the strid... It's hard to fathom that it's that dangerous
what is everyone in the comments being so mean for 😕
People.
meanies!
British affection.
@@anvilbrunner.2013 understandable....
2 parts of the video that are complete waste of time to watch
Cool video! You seem very charismatic
Please do this video again, I would love to see how the bottles bouyancy about
I heard of the shape of this strid just a week ago on another channel - cool to see it in more depth on your YT
Mannnnn Your trying and I appreciate that
The bottles are too small to be affected by the stronger currents 4 feet below the surface.
oi m8 do you have your testing loicense ?
So what is your conclusion?
Man, i remember standing right on the edge looking in, not knowing the danger
Why not just use 1 bottle and see what happens to it. Simplicity is best. Alternatively, tie a weight to an old life jacket, throw it in an see what happens. Too much rope will tangle or snare on the rocks below. Better still, send a heavily weighted camera down the middle of the channel from a sort of stout fishing rod manhandled from the shore, connected to a powerful light source. You need a method to measure flow rates to give an indication of current strengths.
Nice tea coloured water from the peat Moor runoff. I once had an art teacher tell me that water was never that colour.
The head of Biology at my school told me that "large enough samples of semen" couldn't be used in genetic fingerprinting for forensics and to "think about why not." Maybe I should have written an essay about how wrong he was, but I'd only have got detention for cheek. Lying bastard he was. "All sixth formers, especially those studying biology, are cordially invited to attend" after school lectures, according to the notices, and any who didn't got two-hour detention.
I love him cause his an elderly gentleman who said yeet in his last video
"I specifically requested that you yeet!"
Thank you for trying, many say they would or will, very few actually DO!
I'd really like to see you do any future experiments with this river wearing a safety rope tied to a tree.
It would be funny if it turns out the Strid was easily swimmable this whole time since the middle ages.
I’m awaiting part 3 with anticipation
Dude you should totally make more videos to "waste people's time" this comment section is hilarious. People have lost their God damn minds lol. I'll sub when I get through them
Put a GoPro on a long stick and put it in the water and put us all out of our misery 🤠
Water is Opaque you ain’t seeing anything with a GoPro and you ain’t even getting the GoPro back.
@@thisjustin7492 😅 it’s about clarity- I literally take underwater photos for a living ( albeit boring as it’s structures )
Low iq
Interesting video👍
Man's said YEET
I was sitting here bumping my gums to myself, like the rest, but... I wouldn't waste the time to comment that lol I appreciate the try, fellow.
There's a part two!
Place stiff cord between each bottle or you could place straight sections of deburred and reinforced piping over the cord to try and keep them separated. Probably other alternatives.
To avoid the tangling problem, try wrapping the line around each bottle in turn- leave a long enough section between your hand and the closest bottle to reach the water, and hang that section from your OPEN hand in large loops (maybe 2' diameter) so it can pay out freely. You'll probably need someone else to hold the camera, and please use a safety line. I'd quite like you to survive long enough to post a successful demonstration!
What about GoPro in protected box
WOW great man . Am really astonished. You deserve Nobel prize by invented something new instead of Echosounding .
Echo sounding does NOT indicate the power of sub surface currents. Maybe you should watch again to understand his objectives.
Everything always starts somehow and seldom ends there. What is there not to learn from edifying failure?!!
Bud, next time try to set up a tripod so we can see what’s going on.
There are some blurry but decent pictures that a guy with a camera on a rope managed to take.
The streambed on the bottom is almost as wide as the river is before getting to this section.
Do you have a link to that video?
@@bloodymary12100 I wish I did. All I have seen are stills. Search for Camera on a rope at the Strid. Only a handful of stills out there for some reason and I can't vouch for their authenticity. They look reasonable enough given what I've heard about the structures beneath the rocks.
@@mudhutproductions I will check it out.Thank you.
I see what you were trying here. The gradually heavier bottles would appear and disappear as they get pulled or lifted by the currents.
Could I offer a suggestion. Anything tethered together is not going to last long in there. I can only imaging the snags down there.
What about some sort of flow meter on the end of a long pole. I know not as fun.
Don’t tell anyone and go pour luminescent dye at night and watch it flow in the currents. Document for science.
Thinking out loud here. A fishing rod with a lure that's somewhat buoyant but not a surface floater would give you a feel for the speed and strength of the current. Rapala countdown lures which sink 1 foot per second is what I'm thinking of. Lure hits the water and you start counting off the seconds. With a sensitive rod you'll feel the slightest pull or change. Who knows, you might even catch something!
@@jameshickok2349
A fellow angler. All problems can be sorted with a fishing rod. 😂
I think he had it nailed. It just didn’t work as intended. As most experiments end up.
The differing buoyancy in the bottles would be perfect for checking the currents that suck you down and push you up, maybe even move you up stream, at all levels of the stream.
I wonder if i could walk along the bottom in one of them old diving suits.
Anyway them rapala are expensive and it would be snaggy as in there.
the most turbulent section is over 200 feet deep according to another fellow's video with a sonar ball.
The "bottom" that I saw in his video when he dropped the camera down...it looked to be about 40-50 feet or so.
The only test here was the test of the viewers patience
Holy smokes, you want me mum to come out and help you.
Maybe to prevent the line from getting tangeled you should make some slipsticks between the bottels.
They should just toss convicted murderers and rapists into it and study those results. Plenty of test subjects I’m sure.
An interesting idea.
4:52 did you just "yeet" those bottles into the water? 🤣
Something keeps trying to save your life.
Killer earth experiments should always be planed. Including what to do if goes wrong. Well before doing the thing you do
I always had difficulty in "planing" water, the plane just slides over it so quickly. It's far easier to plane wood. 😉
Another great video of how not to throw plastic bottles into a river.
I wouldn't even walk along the riverbank
Be nice to get a medal detector around some of the big rocks ck. for gold ?
Or silver and bronze
Interesting experiment.
old man attempts tosses bottles in stream
My guess is you have some flat earth experiments next🤣😂🧐
I actually already have the flat earth tests posted. Check out "HOH on Greenhow Hill" and "Curved water northeast of Walmer" for example.
This is exactly what happens, it is difficult to understand
This would have made a good Mystery Science Theater episode! 😆😆😃🤣😂
I watched both these videos .... twice lool
Here on Gilligan's island.....
Drop a go pro attached to a huge weight maybe?
Wonder if you could go tubing on that.
Sure thing, for about 10 seconds before you hit a rock and turn over, then get pulled down into a side cave with water forces so strong that you can't get back out.
@@user-tb2jy9lu3d
That would be a no.
@@grmpEqweer Dozens of people are said to have died over hundreds of years. The water is probably 30-60 feet deep. I'm sure the currents are massively strong with that much water flowing through. There may be some myth stuff mixed in with everything, but it is still quite deadly. My understanding is that upstream the width of the river is about 30 feet wide and 6 feet deep that then turns into what we see in The Strid rocky areas where it is only a few feet wide. The river flips vertically on its side sort of like what happens in Niagara Gorge in the USA underneath Niagara Falls. All of that water packed into something much more narrow. It picks up speed and makes crazy high waves. Even above the falls themselves, because of upstream power plants that divert some of the water of the falls...people figure it is about 3 feet or so going over. In fact, during some times the water is 6-8 feet deep or more rushing over the falls. So every place has its unknowns and a bit of myth and mystery.
@@user-tb2jy9lu3d that is one Problem. The next problem are massive undercuts and maybe even half the river floating underneath the Rocks. And maybe water can pass. But humans tend not to.
@@twitchololo They should bring in a small drill and drill small holes along the rock at distant intervals on each side (not close enough to split the rock - like 10 to 15 feet apart) and see how far underneath the rock the water goes. Could even safely drop a thermal/night vision camera in there and look around. Sonar equipment, as well.
If you ever slipped in I wonder if it would be safer to not try to tread water in a vertical position with your legs dangling in the vicious undercurrent and instead try to stay horizontal and swim across the surface to somewhere you can get out ?
Use a single rope for each of the bottles and longer rope
Do a depth test
Skip to 6 mins. You're welcome. Plus, you dont even see the "experiment" just him standing there throwing the jugs.
Yes, what a complete waste of our time!
This comment gave me more valuable information than the video...
i mean he kinda still explained tho, like in this vid the part of the river where he is was unexpectedly calm despite there being claims that the water beneath are actually very turbulent and is gonna "suck you in". those jugs are really not the best experiment model but at least he tried.
thank you!!!
6:03
I have caught a brown trout in the strid on a fly rod
Huh implies the currents aren't terrible in some spots
A great impersonation of Stan Laurel, should have brought along an Ollie to hold the camera :-)
It's the only camera I have! I don't want it falling in.
@@Sableagle No offence intended it's a great worthwhile endeavour, but I found it amusing the way the rope got repeatably tangled. I visited the Strid in 2019 to take some long exposure photo's and felt very uneasy near the edge. The parents of the children in your videos need educating about the dangers of the site.
I SPECIFICALLY REQUESTED THAT YOU YEET!
YESSS !!
About the only thing you accomplished was creating a birds nest with the rope. Fascinating.
This is a bit to scientific for me
The amount of string this guy is using is giving me hives..
Also, said string will inevitably end up getting caught around a rock and it will all get stuck under water
Can someone please send a drone in, I'd do it myself but I'm in Australia, and we swim in very deep passages just fine
So the force of the current is approximately unknown.
I just don't understand what ropes and jugs half filled with water is supposed to show. Not being critical, I just don't get it.
Expand the scale of the Strid (both width and depth)by a hundredfold or so and you get the lower Congo
What are we supposed to SEE?
Thanks God there's no 3rd part..
He might have fell in making part 3.
I wish he would go where it looks calm but is deadly. Obviously, it's deadly there.
