Extreme wood bending with ammonia softwoods are so named because their seed coatings are soft, not because the wood of the tree is.
you can bend balsa wood just by soaking it in ammonia/window cleaner with ammonia a lot of model builders use this technique
Will ammonia react with PVC?
okay but how do I open the pipe without filling my workshop with ammonia?
Composting fresh grass clippings produces lots of ammonia and heat.  Perhaps tossing some wood in the compost bin for a day would yield a similar result.  

I wonder why the soft wood did not fare so well.  Does it have a different ratio of lignin to cellulose?
How does this compare to steam-bending of wood? I know that process is often used by crafters and even shipwrights.
I don't even want to know how you vented that pressure vessel unless you had a chemical neutralization for the ammonia.  Yow.  Do you have a fume hood or anything?

People die from ammonia induced pneumonia in lab accidences.  I spent a week in hospital for an SO2/Cl2 burns.  I know where of what I speak.  I got less of a charge than you had in the pressure vessel and I was working in an OSHA compliant industrial lab.  My view port popped just as we were setting up the video camera.  Not fun at all.

You scare me.
I always remember you as the DIY TCMS guy. You seem really well adjusted though. No pun intended?

Cool video from Applied Science.

Bending wood with ammonia is not really DIY, but I show the process, which is extremely effective. There is also a commercial product that is pre-treated flexible wood, which hardens after being clamped in the desired shape.

Teflon tape isn't for sealing threads, contrary to popular belief. I have been in the heating and air conditioning trades for well over 30 years. Pipe dope of various types should be used to seal the threads. Teflon tape was introduced as a lubricant for the threads so that another 2 or so threads could be gotten into the fitting. I rarely use Teflon tape at all. If you use pipe dope instead of teflon tape, you can draw down a vacuum as deep as you'd like in a tiny pipe chamber like the one you were using in this video.
2:56 "we just need to flow ze gas in ze chamber" Damn is that jewish wood? Not implying anything just joking around a little :)
Run away, hehe.
Could you please tell me ?what or how did you got into this project.  This is my first visit and I think you are more curious about our planet than I am.  This is to me is top shelf good work thanks for all your hard research.
As a chemist with a bit of common sense i can say that it's a bad idea to heat up a pressurized canister of anything above room temperature. If you do be ready for the potential of an explosion (not saying it will happen, it's just a possibility which increases the more you heat it).
fahrenheit in a science video, shit I had just subscribed
that's a cool process, but you can do almost the same thing when you sooke wood in water and heat  the wood with a heat gun
+Ben Krasnow you must really make a video about graphene and its properties and most importantly how to make some at home !
5:59 That looks like one of those photorealism drawings.
I wonder how this compares with steam bending?
The last woodbender.
