That's nothing!!  go swimming off the coast at Sellafield , and you will emerge all the colours of the rainbow.

It's probably Phospherous.
Happens from time to time, I seem to remember as a kid seeing it off the Essex coast.

Glad to see you posting, STUDYFORM - we were wondering if you had got banned after what you said the other night.

I know it is a pain watching what you say, but it would be such a shame if you did not post again.

I've been not posting out of choice, annie.
I've been surprised by some people. Not by others.

The place has become a (not) think tank which so many others have left, I'm on the edge of joining them.
It's all a bit boring, frankly. The topics are limited, the trolling rife, the general tenet unbending and unreasonable.

Nice that you're pleased to see me all the same.

Perhaps we could think up a forum that all those that are banned can join, a forum where we are able to talk like grown ups with freedom of speech.
