I agree and I don't see why he couldn't have just used a smoke bomb. I don't see the big difficulty of demonstrating this valve like he mentions at the beginnin

  In this particular case, maybe he didn't have a smoke bomb. He clearly isn't a stranger to this sort of thing but he has online commentators commenting that he failed to properly demonstrate the valve. Pretty solid evidence that the valve is hard to demo. On a positive note the observation about gas expansion probably makes the whole thing more interesting than a plain demo of the valve. His demo is better than a smoke bomb demo.

  It would work with fluids also, wouldn't it? It would be cool to watch it submerged in a clear fluid, with a colored fluid forced through in one end.
