I had no idea they made boats by blowing up a giant plastic balloon and crushing it in a giant smasher machine, that's amazing

What's the method named? Something about casting

I wish engineering was just this all the time and not designing weapons for "defense" contractors 🙃

The roller and the guy with the shovel jabbing it underneath was making me anxious

Printing boob!

Is it not a variation of vacuum forming?

Transmutation, probably.

Thought it might be conjuration at first, but that's creating stuff from nothing rather than reshaping matter..

Oh, that's not the kind of casting you mean? Carry on, then 🤷🏻

I hear Factorio calling...

This is blow molding, more common for soda bottles. Closed-top boats like kayaks are typically rotomolded instead.

Rotomolded?

The way it was spinning it looks like it would have kicked it out, rather than pull it in. Looked almost counterintuitive.

I want to be the nail magnet guy. So satisfying.

That one really called to me also. I'm not sure why.

Inside-out vaccum forming, basically.

Squirt some liquid hot plastic into a closed mold and rotate it to coat the inside while it cools.

How do you control for thickness there?

Definitely transmutation.

I'd rather it be done via thaumaturgy with a blind, wizened master sitting nearby shaping a tiny version as his family has done for centuries.

that 3d stamp boob used to be so expensive. it probably still is.

Likely amount of liquid and amount of rotation.

I'd let this thing give me a face tattoo.

Which one of the things do you mean? The nail magnet? 😛
