Stout proof of falling bubbles (Ananova)
Scientists have shown that the bubbles in a pint of Guinness really do move down instead of up.
To mark St Patrick's Day, a team of Scottish and US researchers has produced video evidence to show the bubbles being dragged to the bottom of the glass.
An earlier study concluded that the phenomenon may only have been an optical illusion.
