'If paper efficiency is your goal when wrapping a football, you may want to experiment with a triangle of foil. An international team of scientists studied how Mozartkugel confectionery – spheres of delicious marzipan encased in praline and coated in dark chocolate – are wrapped efficiently in a small piece of foil. They observed that minimising the perimeter of the shape reduces waste, making a square superior to a rectangle of foil with the same area.

'Creating petal shapes are another way of efficiently covering a sphere – although it would require an infinite number of petals to do this particularly neatly. The researchers discovered, however, that an equilateral-triangle wrapping that is even more efficient. "It's area savings of 0.1% may prove significant on the many millions of Mozartkugel consumed each year," they wrote, with a possible 20% reduction in material needed to cover a spherical shape.'
