Stephen Fry explains... How lightbulbs work

Yesterday was Thursday, today is Fryday, tomorrow is Saturday...

Competition It's Fryday and the sun is shining. As requested, you lot have have been trying on the tweeds of our National Treasure™, Stephen Fry, to come up with Fry-style technical explanations.

The best of the most recent bunch is sent in by Michael Harper, who contributes this.

So picture the scene. A TV studio is filming a general knowledge panel quiz. Arabella, the unpaid intern who normally does the research has done a runner, or gone skiing. There is no access to Wikipedia. But the nation's favourite technophile is on hand, to save the day.

How does a lightbulb work, Stephen?

Well done Michael, we're still thinking of a suitable prize. Do keep them coming – and remember, technically accurate explanations are completely out-of-character, so keep them Frytastic.
