Does a teaspoon keep champagne fizzy?

Chris - We're almost out of time but we've got this one here from Kitty. We can have a sort of show of hands on this - does putting a teaspoon in the top of a bottle of champagne stop it going flat? Who believes that one?

Helen - I've never come across that actually. That's the first time I've heard that.

Chris - People say it stops it going flat, but it's not true. It's a myth I'm afraid, Kitty. It doesn't work.

Ramsey - Yes, the air is still exposed in the champagne.

Chris:: Yeah. I mean basically, the gas under pressure dissolved can bubble out and escape and the teaspoon does not make any difference.
