The Fizzics of Bubbles

Published: 29 May 2007

Sparkling insight from scientists

They make our Champagne sparkle; they fizz-up our beer; a pint of Guinness just wouldn't look right without them.

The lowly bubble has a hard life: always under pressure, and always on the move. Kids love them, and to be honest, adults do too.

But where do bubbles come from? Why do bubbles rise faster in champagne than lager?

We've seen reports that bubbles in Guinness go down - what's that all about?

Dr Andrew J Alexander form the School of Chemistry at Edinburgh University will help you understand the fizzics and chemistry in a glass of beer.
