I have a table lamp which lights, changes brightness & goes off in

Perfect for where it's used, but it's pink! The base seems to be some
kind of pottery. If I paint it with emulsion - will it still work?


My mother had one by her bed. Got it in Aldi IIRC. Much easier than
groping in the dark for a switch. As to whether painting it will stop
it working, I've no idea, but you could try a postage-sized patch
round the back as an experiment, or even touch it with your hand in a
poly-bag or rubber glove, to see if conductivity is important, or
whether it's a capacitance effect.

I understood it is capacitance.


Wot dat?

Black magic. Or in your case pink magic.

A worried father confronted his daughter one night.
"I don't like that new boyfriend, he's rough and common and bloody stupid with it."
"Oh no, Daddy," the daughter replied, "Fred's ever so clever, we've only been going out nine weeks and he's cured me of that illness I used to get once a month."
