TIL about Wirtz pumps. Put a hose in a vertical spiral and spin it in a body of water and it'll pump water through the hose with way more pressure than you would think.

Ramps are so amazing. Thanks for existing, ramps. You make so many things possible.

Yeah, but what about levers?
- Goddamn dude are you tryna get married or what? talking dirty af to a motherfucker right now. I like your roll.

  I'm inclined to get sprung if you wheely keep pulleying my strings.

Took one look at that thumbnail and knew it was a Steve Mould creation. He has a very distinctive style to his water models.

Blue water and acrylic side panels?

Actually just watched this before I saw this post. Great video and very informative!

Matt Parker looks so insanely different with that beard.

Steve Mould is a great YouTuber. Up there with Technology Connections

Isn't this a scroll pump?

No, beyond both being spiral shaped they have basically nothing to do with each other

Also: I don't know why they're making them as strict spirals. It looks to me like anything that's just a coiled hose with a large coil radius will work just as well, and you don't have to carefully construct this strictly flattened shape for your machinery.

So, basically an Archimedes Screw.

Nope. The airlock effect inside the mechanism produces an additive effect with each coil that builds the pressure way beyond what a normal screw pump is capable of (he shows a friend who has one that pumps water to a garden 8 meters above just from the force of the river spinning it). That's what makes it worth its own whole Steve Mould video.
- Thankyou for making me watch the video. I wish I knew the math behind this.
  My high school math teacher would be shocked to know I have written such a sentence. It's a pity educational tech wasn't better back then.
- Neat. I'll check out the video when I get the chance.
Yes, but flattened
- You say flattened, I say dimensionally simplified. We are not the same jk
