We
are used to seeing bubbles float up
in a glass of beer, but bubbles in
Guinness appear to break the rules.

the head?
Here we show you some video proof that
the bubbles in Guinness do actually
go down the inside of the glass just after the beer is
poured. To learn more, click on to one of the bubbles opposite,
or use one of the links below.

bubbles go down?
Does
it only happen in Guinness?
