We put two chocolate bars to the test in a Battle of the Bars… and the results are in! After rigorous 3-point bending tests, the winner is (drumroll….) the KitKat! Our mechanical testing consultant Dr Ben Cunningham found that the Crunchie has an Ultimate Flexural Strength of 180 kPa, the Wispa has 830 kPa, but the KitKat was the clear winner at 1,680 kPa. See the video for footage and graphs.
