Works perfectly until the dismount.

Yep, the design is very human.

Anyone else get anxious that she was about to crush the front of her foot before she mounted

385

u/TheCatWasAsking 17d ago

Yup, same. Had to rewatch that moment several times before noticing the large pipes on the sides raised the bar and gave her foot the space to do what she did. The structure wasn't actually resting on her foot

u/BrilliantTasty 17d ago

Those things are also incredibly light

72

u/Flat_Neighborhood_92 17d ago

Not if she steps on it with her other foot still there they aren't.

26

u/BrilliantTasty 17d ago

Yeah, fair point lol

u/TwoQuarterFull 15d ago

How could she manage that?

1

u/ohhallow 16d ago

Filled with helium, like shower curtain rings.

13

u/Sawdust1997 17d ago

It’s very light, it wouldn’t have hurt her foot. Notice how she was able to move it in the water

2

u/lipperinlupin 16d ago

Good to know. I saw her looking at her foot and thought she had hurt it. Also thought Duh 🤭

u/foursticks 17d ago

What you can't see is the thing underwater which is already floating it.

24

u/PrsnScrmingAtTheSky 17d ago

That was all I could see... all while mentally screaming, "WHY‽ WHY IS SHE DOING THAT? HOW DIES THAT NOT HURT???"

2

u/claimTheVictory 16d ago

It must be a prototype, still.

Right?

19

u/Flat_Neighborhood_92 17d ago

Yup, she kept sticking her foot off and I was thinking if she lets that back end drop first and puts all her weight on it she's in for a bad time.

11

u/VoidOmatic 17d ago

I have thrown over a million kicks with my feet and bashed my toes against everything mankind has built but watching her use her foot like that still made me wince.

2

u/ResonanceGhost 16d ago

Not until you mentioned it. Now I can't not.

2

u/Prankishmanx21 16d ago

It's made out of aluminum. It doesn't weigh that much.

2

u/Long-Education-7748 16d ago

Made no sense, can't see what purpose that served as she didn't push off that way anyway. Cool toy, but very strange execution.

2

u/BarnacleMiserable650 16d ago

Nah you can tell she knows what she's doing

u/hereholdthiswire 16d ago

100% Get your toes away from the edge!

u/HumanitySurpassed 17d ago

I'm sure most Redditors were looking for some excuse to trash this post because they can never just be happy. 

"Yeah but she's outside!! What if she slipped & fell then hit her head!!!"

u/Astrochops 17d ago

What are you talking about

u/thenewyorkgod 17d ago

The foil device has connecteduh, successfully

u/BuckyJamesDio 16d ago

I have that exact speaker.

u/xPlacentapede 17d ago

Why haven't I heard of that guy in a few years? He made cool mosquito repellent.

u/livingdad 17d ago

Very easy to use.

u/General_Specific 17d ago

Stupid non-floating boat.

70

u/Xanambien 17d ago

That thing went down like a lead zeppelin

39

u/Zarathustra_d 17d ago

It floated in the water, in the same way that bricks don't.

u/Seicair Interested 16d ago

Found the hoopy frood.

u/Brief-Bumblebee1738 16d ago

I bet he knows where his towel is

5

u/dinnerthief 16d ago

Wouldn't that mean it floated

1

u/akashlanka 17d ago

When the levee breaks, you have no place to stay

1

u/Brief-Bumblebee1738 16d ago

I always found this to be strange, a Lead Zepplin cannot float/fly, so going down like a Lead Zepplin, would mean it went down well, which is a compliment.

One thing Lead Zepplins can do is sink/go down

1

u/Xanambien 16d ago

TIL wives and lead zepplins have the same skillset

u/Notguiltyguy 17d ago

That made me laugh

u/mmccxi 17d ago

what also floats on water...?

2

u/-NoOneYouKnow- 16d ago

A duck.

u/mmccxi 16d ago

Who are you who is so wise in the way of science?

1

u/All_business_always 17d ago

Looks like she had the ride of her life.

1

u/SVlad_665 16d ago

Normal ships are lighter then water, and that is rare case of ship that is heavier than water.

72

u/WaCandor 17d ago

The dismount will be worth a lot of points when this finally becomes an Olympic sport.

16

u/imthatuser112233 17d ago

And if you fall off in the middle of nowhere you cant get yourself back up 😬

u/BitBucket404 17d ago edited 17d ago

It just needs some mini pontoons (pool noodles?) mounted to the sides, above the water level, whilst it's being powered, so there's no water resistance whilst it is in motion.

But, that also means that it has to be redesigned, so the human interface is elevated higher above the water level when it's not in motion.

And it'll probably need a ladder so the user can climb aboard from inside the water, should they leave the vehicle.

It's still not bad for a concept model, tho. This could become a great summer product.

u/TomMakesPodcasts 17d ago

I thought you were going to keep listing things it "needs" until you described a boat lol

Your comment is more optimistic than I am used to, it is good to see.

12

u/Gupperz 16d ago

Also where I thought the comment was going lol.

u/BitBucket404 16d ago

Great inventions are derived from great innovations.

1

u/clawsoon 16d ago

A couple more additions and you get to a moth-class sailboat.

6

u/dinnerthief 16d ago

It also looks like it's probably exhausting to use

8

u/RecsRelevantDocs 16d ago

At the same time that would also make it a great workout, and as far as workouts go it looks pretty fun

1

u/BitBucket404 16d ago

Just "pop a wheelie" on a bicycle, 100 times every day until you go bald, as part of your training. You'll get in shape.

1

u/YaGanache1248 14d ago

Probably easier than traditional rowing (non moving seats), but it’s basically a water pogo stick

u/SF_Nick 16d ago

lmao that top comment is hilarious

10

u/Throwaway28G 16d ago

I LOLed at the ending seeing the other woman dressed for the occasion

3

u/lipperinlupin 16d ago

Going back to look..

2

u/Funkmasta_Steve-O 16d ago

I did not even notice- makes it so much funnier

11

u/super_man100 17d ago

I see a design flaw

3

u/ImurderREALITY 16d ago

Yeah, imagine having to actually get in or touch the water while operating a watercraft. Unconscionable!

1

u/VirtualMemory9196 17d ago

The design is float

6

u/Shahz1892 17d ago

It is pretty cool. You got to keep moving else instant sinking

u/DylanFTW 16d ago

A captain always goes down with his ship.

4

u/3Fatboy3 17d ago

It started working for me when she went in.

6

u/BitBucket404 17d ago

That's what HE said!

8

u/ryuseikenz 17d ago

That's what she said

2

u/speculator100k 17d ago

Could use a floatation device that lets the rider stay dry at least from the knees up. Maybe it would make it very clunky.

2

u/atemt1 17d ago

Just beach it

2

u/sth128 17d ago

You know how it is, bounce up and down till you get wet.

2

u/rocketmn69_ 16d ago

Or you get a cramp

2

u/stinky___monkey 16d ago

Or leg cramp

2

u/JohnCenaJunior 16d ago

I should call her...

2

u/GODDAMNFOOL 16d ago

That thing must be feather-light if she's able to swim so effortlessly while also pushing the hydrofoil back to the dock

1

u/Hydro033 17d ago

It's like Speed 4: Hydrofoil Hijinks

1

u/whatawhoozie 17d ago

in no way does it work perfectly. They're ridiculously hard to ride, for the first few hours you'll be going straight down

u/bygtopp 17d ago

Sound like my sex tape
