Staff at the Mcvitie's laboratory in High Wycombe, Bucks, designed the Crumb Test Dummy to test which baking techniques produce the most crumbs. The motorised mannequin has plastic teeth and is designed to replicate human eating.
"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," Mcvitie's brand manager Liz Ashdown added.
"The Crumb Test Dummy has a never-ending appetite and doesn't need to stop for breath."
She did not add, "And it absolutely will not stop until you are dead."
