The debate over which biscuit is best for dunking normally comes down to a matter of personal taste. But the more practical question of which can soak up the most tea without crumbling into the cup has been subjected to the more exacting scrutiny of science. Ten types of biscuit, ranging from Fortnum & Mason pistachio and clotted cream to children's favourite Fox's Party Rings, were dunked to see how long each lasted before losing'structural integrity' – science speak for how long before they crumbled. In a separate test, the amount of tea each could absorb in 15 seconds was measured. The winner was the McVitie's Rich Tea with nine points out of a maximum ten – holding together for an impressive ten minutes before starting to disintegrate, according to Wired.
