So what’s that about? Gases trapped in and in-between the paper?

D.H. Lawrence? More like Lady Shatterly’s Lover, amirite?

Would be interesting to see the temperatures inside the stacks. I suspect the pressure raises the temps so high, there’s a chemical reaction with the dioxins and other muck inside the paper.

I’m betting that under pressure the lignins themselves are fusing into a solid material, when under further pressure shatters. I’d love to see some of the compressed waste from these “experiments”.

Seems more like tearing. Once enough tears happen then the pressure on the paper becomes uneven and so it moves laterally, fast, in an avalanche of tearing.

There was an early video of theirs with an attempt to fold paper 7 times with the press, that had a similar, though less dramatic, conclusion, and shows that it does indeed become a rather brittle solid after critical compression. I think you’re on to something.

Velcome to de Hoodralek Press Channel, I love this guy’s accent, very charming.

The hydraulic press channel is the best thing on the internet. Well actually the second best thing. The first best thing on the internet is the beyond the press channel. That is the one where the folks from the hydraulic press channel go outside and do a bunch of shit that is even weirder than smashing random objects with a 2 ton press.

In this one they see if 2kg of solid steel heated white hot will melt through the ice of a frozen lake. https://youtu.be/cOEBwBERPv4

These two are out of their minds.
