It is to have in my backpack when I go off on one of my jaunts. I have waterproof paper so just need the pen.Whats it for? Writing a diary in the rain, or marking something important so it remains legible?
If you like.Is this the time to wheel out the urban myth about the NASA guys using a space pen but the Russian cosmonauts using a pencil?
I went into our local stationers and asked if they had a pen that wrote both underwater and upside down.
"This one does. Let me demonstrate," he said and wrote something on a piece of paper which he passed across the counter.
I read underwater and upside down.
