Skimming 'Potatoes'?

Applied Mathematicians (The University of Bristol and University College London) have produced a model, predicting that more impressive skimming can be achieved by using potato-shaped stones. This runs counter to the general belief that thin, flat pebbles produce the best performances across the water (https://www.theguardian.com/science/2023/jan/04/potato-shaped-stones-are-better-for-skimming-say-experts). This is not, however, simply an entry for the IgNoble awards (where weird science is rewarded). The model is being developed to predict the effects of wing ice, changing the flight characteristics of aircraft.
