A bubble is formed when a layer of water molecules is trapped between two layers of soap molecules. Each soap molecule is positioned so one side faces the water, while the other faces away.
No matter what shape a bubble creates when its first blown, it eventually forms a sphere to minimise the surface area of the structure. This shape uses the least energy to form.
Weight savings are crucially important in aircraft manufacturing, since a lighter aircraft requires less fuel, which is airlines' largest operating expense.

Physicists have reported the most accurate test to date of Lorentz symmetry for photons by looking for variations in the speed of light, but found no violations. The study, by Moritz Nagel at the Humboldt-University of Berlin, Stephen Parker at The University of Western Australia, and their co-authors, is published in a recent issue of Nature Communications.
