Researchers have used gold in recent scientific trials to explain the existence of non-spherical bubbles.

The phenomenon had been observed on a variety of surfaces, but up until recently, had baffled scientist.

Researchers from Harvard University found that the non-spherical bubbles could exist on surfaces like gold without the existence of an external force on them.

They were able to explain this by showing that the bubbles are coated with a layer of tiny particles fused together, which gives them the non-spherical shape.

Research leader, Bala Subramaniam and his colleagues used gold as an example of a surface where particles fuse together to create an "armour" coating, giving rise to the odd shapes.

Now that the phenomenon has been explained, it is hoped the discovery can be put to commercial use.

Vivky Joseph, Mr Subramaniam's adviser, said: "Bubbles are engineered into many consumer products. The ability to alter the shapes of bubbles and liquid drops in products like ice cream or shaving foams or creams may provide a means to alter the consistency or texture of these products.

"The non-spherical bubbles could also find use as vessels for delivering drugs, vitamins or flavours."
