The first time I did this I was a boy, living on a kibbutz in Israel and missing my mum and dad terribly. I remember the rush of joy when the cloud disappeared - it was like a promise of better days to come.

A couple of years ago a music magazine contacted me to help make the sun shine on the Glastonbury Festival - famous for its downpours and quagmires. I spent the whole weekend cloudbusting, and the show enjoyed scorching summer sunshine!

Maybe you think it's a mad idea, but have a go. It'll put a smile on your face!

To warm up your psychic sense, try my weekly Challenge. I'm astounded by the accuracy of your responses: last week XX per cent of you received my telepathic signal correctly.

Stare at each sign in turn, and hold your hand above them to pick up a dowser's signal - a sort of warm electric tingling above the correct symbol. Believe in yourself and the rest will follow naturally.
