In the latest Amazing Spider-Man comic (#682), Spider-Man goes of to space and finds himself unable to operate his spinnerets inside the space station, even though there is air remaining. Is there any explanation for this? He's not in a vaccuum, and he seems to act as though it's an obvious consequence of zero-g, and thus no explanation is given. I can't see anything detailed in my previous question that would suggest space would interfere with his webs as they rely on pressure to shoot.
N.B Later on he is in a vaccuum (they flush out the air to knock out zombified crew members) and uses his magnetic webbing, so I don't think it's the vacuum that stops the spinneret device from working with normal webbing.
Why don't spider webs work in space?
