Experts at the McVitie’s laboratory in the UK have invented a mannequin with a motorised mouth to test the amount of crumbs biscuits produce.
The Crumb Test Dummy is fed biscuits made using different baking techniques to determine a consistency which produces the amount of crumbs consumers expect.

Tests found a packet of 18 digestives should generate around 1.8g of crumbs when eaten – or between 0.08g and 0.12g of crumbs each.
Liz Ashdown, brand manager at McVitie’s, said: “Eating lots of biscuits is obviously an enjoyable prospect for most people but we haven’t yet found a human who can test on this scale.
“The Crumb Test Dummy has a never-ending appetite and doesn’t need to stop for breath.”
