Wiping the dust away was getting to be annoying, so I hunted around and found a piece of rubber tube. Stuck one end up under the mask and in my mouth, and clipped the other end to the cutting board. Hey that works OK.
Soon I started salivating - a bit like Pavlov's dog, I had to remove the hose a couple of times so I could swallow.
Got a bit hard to blow after a while, and I thought the clip had squashed the hose flat. No - so I just blew a bit harder and spurted a stream of saliva over everything.
Turned off the light and went inside.
