Scientists find the ‘perfect Christmas cracker pull’

SCIENTISTS have derived a formula for “the perfect Christmas cracker pull”. According to research organisation QinetiQ, the best snap is produced by keeping a firm, two-handed grip to prevent the cracker being torn at your end.

Tilting your end of the cracker downwards at an inclined angle during the pull is also said to help.

After stringent laboratory tests, a team from QinetiQ’s human sciences division concluded that the perfect pulling technique depended on seven key factors.
