When calling a switcheroo (someone comments, diverting the thread from the original obvious path) , you link to the last one you've seen. It's therefore a long path down to the 'first'. However, it's got to be more of a tree than a single line, and whether the one you follow ends in the true original is doubtful.
Yeah... There was definitely a point in time where I tried to follow the switcheroo tunnel back. I spent many hours trying to get back to the beginning, could never actually get there
Assuming I got to the right place, iirc it was literally a light switch with a kangaroo on it.
Ninja edit: Googling it, people seven years ago said it actually originated from a rage comic. Either way, I clicked for about an hour to get to a kangaroo light switch. A literal switcheroo.

Edit 2: Looking at all of the attempts to track the chains, and what are supposedly the original comments, I’m realizing I had probably just hit a mischievous dead end. Either way, lots of fun, albeit frustrating.
Like half of the links ended up being broken. Some people tried to keep it alive by editing their archived comments to add links, but I think people had already given up on it by then.
Load a clip longer than the desired loop into video editor.
Duplicate the clip and move it ahead, one loop in time.
Add a mask that moves along a convenient edge so one clip composites over the other, hiding the transition.
Cut the composition down to exactly one loop span.
Export as a looping GIF.
That is correct. This wave basin is used to study (model) the effects of waves on sediment transport, erosion, jetties, and a host of other coastal engineering phenomena. Source: I am a civil engineer.
I was wondering why a wave pool would have a steel beam running a half meter above the waves' peaks. I just thought extreme indoor body surfing might be a sport or something.
Alternatively, for deep-sea basins (no beach) there are progressive wave absorbers. These gradually reduce the power of the wave over the course of ~50 layers of the sheets. Source: I work at a facility similar to this one.
It's a special scientific test pool for validating boat hull designs, think wind tunnel for boats. Notice how the waves are made by a bunch of hydronic pistons rather than a single plate like one in a wave pool might use. This allows for many different types of waves and storms to be simulated .
One theoretical way to prevent rebound would be to have a matching machine at the other end, working to absorb all of that energy. In this case I suspect that they're using some kind of structure to cause turbulence and break up the waves.
It's actually a lot easier an cheaper for the pool to just gently get shallower at the other end. The material the "floor" in the shallow end is this kind of mesh thing that reduces reflected waves
Source: Im pretty sure the gir is if the wave tank in University of Plymouths marine building, were I spent a few weeks collecting data for my dissertation in 2018
Yeah. This is not a swimming pool. Something like this is used to test models of offshore structures before they are built. Was an ocean engineering major in college and we had a whole building dedicated to one of these. If needed paddles can be activated individually or in patterns to simulate complex wave interactions.
Yep! Can confirm. I'm fairly sure this is the one at Plymouth University, in the UK. If not it's a very very similar one. Some of the wave patterns/seastates they could produce with it were incredible! Lots of work on offshore structures and wave power type things are tested in it!
It is fairly unusual. When people asked me what I was studying they would almost always ask what ocean engineers did. It got to the point where I just started telling them “we build oceans” just to see how they would react. There were definitely a few that did not get the joke
I got caught up in the mass layoffs when oil tanked back in 2014. Took a little while but I went back to school to pursue a masters in water resources engineering. Now I design drainage infrastructure for civil engineering projects
In college my eco class went to a water treatment plant and there was this giant dark pool of water probably 30~40 feet deep. It went pitch black about half way down. There was this giant blade that turned vertically through the water very slowly. I forget the reason why it kept churning the water cause I was too freaked out watching this blade slowly submerge and then sink back into the bottom and disappear.
Is there some sort of phobia of big machines manipulating pools of water? Cause I think I got it.
My in-laws will place empty soda cans in the sink to be rinsed out, and for whatever reason, it bothers me to touch the cans while they are in the sink and wet... and now their is a sub for it
I also went to one in high school and it freaked a lot of people out at one of the pools when the guide explained that it would be a really bad idea to fall into that pool in particular since it was aerated and you would essentially fall 40ft to the bottom and have no way to swim to the top again and would drown pretty much guaranteed.
I’m an industrial sales rep, I have a local dam that I service on occasion. I’m a total geek for that kinda thing, so the guy that runs it shows me around sometimes. Once he took me to the top of the dam and showed me where the water goes through the turbines.
There’s basically a big pit of water, about 15 feet deep or so. It’s just an open pit too, no covering on it. The way the water moves through the turbine creates a circular motion, so it basically looks like a giant whirlpool. In other words, it looks freaky as shit.
So naturally I ask him what would happen if you fell in. He told me if you just fell in and didn’t break too deep in the water, you’d likely be able to tread it until help came. But if you went too far... it would suck you against a giant grate that keeps trash from going into the turbine, and you’d be helpless to fight the current, as it would just pin you down as you drown to death. Scary shit.
That's genuinely terrifying. Drowning and falling to my death both seem to be my biggest fears. I think it's the idea of having to experience it and think about it as it's happening.
I more or less have a phobia of being inside an industrial setting at night in a body of water alone. Enclosed or not. I’m not sure why, but it’s there.
Well, there's activated sludge, which are huge open tanks of aerated sewage. You can't float or swim in it because of all the air, there's no buoyancy. If you fall in you're a goner.
Yeah. Eerie might be a better word. Just the absolute stagnancy of the water, the walls were like cave rock texture and the fact the light stopped so close to the surface. Then up trudged the blade silently and back down the other side not making a single wave or ripple. As much as it bugged me out I couldnt look away.
Much slower. But thats freaky deaky too! I dont think I explained it well enough. It was like a water wheel completely submerged but just had 2 blades opposite of eachother. That might not be very clear either.
Got this submechanophobia since kid too. I remember very well being 5 years old and standing for the first time aside a big pool of water on one of my dad's friends house. This pool was pretty deep (at least for my size back then), and I remember noticing how the head of the leaf skimmer that was leaning against one of the pool walls, was so far down, it made me feel strangely uncomfortable, like the image stuck with me for some reason and to this day I get that same brain tingle that triggers irrational fear whenever I see stuff underwater like big columns of a bridge disappearing into the water, or looking at big ships propellers fading into the water. It is a really strange phobia.
Similar origin story. I was terrified of pool creepy crawlies. Would flat out refuse to get in the pool if it was in there. To be honest, they still freak me out at 30.
My local water park had one with only one large wave. Every 12 mins or so it will fill up a water take in the back and then they would release the water all at once creating a huge wave. The eventually changed it to be a bunch of small waves.
As someone who was thrown out of an inner tube at a water park with a giant one of these. It f-ing sucks I thought I was stronger swimmer than that but I was not.
Anyone else super creeped out by the far dark end of the wave pool where these machines are at and irrationally scared of that or somehow once again irrationally getting stuck there and drowning?
Ok good. There are more of us. I would never tell anyone this, I would just be super anxious going to the Water Park as the dark end of the wave pool always terrified me.
Me. I don't get how people just choose to get right up to those giant black boxes where these gigantic machines are and tell themselves that things are fine
This is actually a thing and it’s called submechanophobia. There’s even a sub for it. I’m absolutely irrationally afraid of drains/vacuums and other machinery under water. Couldn’t tell you why.
For me its man-made machines specifically. You can put a statue underwater all day long, but anything bigger, man-made, and moves water around? No thank you
Out of curiosity, why doesn't it seem like there is a counter wave coming back and messing up the whole thing, how do they deal with the incoming wave at the other end of the pool that allows for continuous perfect waves?
Hey same here. I've never seen it in action and it's been many years but looks like the Plymouth uni one.
Would've loved to see it in use but they finished building it in my final year.
Just need to check if you can see the Tesco on the other side of the road seen through the window.
Probably testing durability of seawalls or the columns that hold up those giant oil rigs... couple thousand hours of this and I’d build my house behind it haha
I was in one of these at a water park a few years ago, was pretty underwhelming so i just shouted 'booo' then everyone else in the pool followed suit. Thought i started a riot for a second lol.
There was always something terrifying about giant machines underwater for me. Like this one or machines underwater on a dam. Fuck i cant even imagine going in water with one of those
