tight corners seem tricky to get all the air out of

[@BrooksMoses]

I think it would be interesting to take an inflated cube or tetrahedron, cut it open at the seams, and flip all the panels inside-out to make a "deflated" shape.

[@ConnorHolland]

That would work, it would also be interesting to try deflation with a vacuum pump

Cool man

You were just testing out your Father's H20 welder wasn't you? I seen it this morning on TH-cam as well!! 😁

[@mythrail]

does it make any sense to hydroform in to a mold for more complex shaping possibilities?

[@xploration1437]

Try some with copper sheets. I bet it bends easier since it is softer.

[@ConnorHolland]

I would like to try forming both copper and brass sheet, I haven't yet as steel is much cheaper. Would be worth trying for a future video

What if you made a stove out of some of those spheres & shapes.

Try the pentagons

Hello😊. Great job you are doing👍🏻. Will ask you about how much you think should be added in millimeters if it now has to fit together with an item you already have. Sincerely, Lars from Denmark.

[@ConnorHolland]

Thanks, I would say that it is hard to predict precise measurements, as every shape behaves slightly differently. I usually inflate a prototype first, then adjust the design to match the requirements

[@larslindthomsen7370]

@@ConnorHolland Thanks for the answer. It's because I'm missing the lid on my pillar drill. Sincerely, Lars from Denmark 😊

[@smurfprod8347]

You should make a hydraulic press that works with water as an "inflation" medium. I think it would generate more tons of force than a pressure washer and you could have results at another level.

This is why planets and stars are spheres.
