Soap Bubble Structures by Kym Cox. Bubbles optimise space and minimise their surface area for a given volume of air. This phenomenon makes them a useful tool in many areas of research, in particular, materials science and “packing” – how things fit together. Bubble walls drain under gravity, thin at the top, thick at the bottom, which interferes with travelling lightwaves to create bands of colour. Black spots show the wall is too thin for interference colours, indicating the bubble is about to burst. (Photo by Kym Cox/2019 Science Photographer of the Year/RPS)

A recent undated handout picture released by the Guinness World Records on September 9, 2014, shows 49-year-old trick golf artist Karsten Maas, from Denmark, who secured his place in the 2015 Guinness World Records book for creating the world’s longest usable golf club. It measures 4.37, (14ft 5in) in length and has been used to drive a ball a distance of 165.46m (542ft 10.16in).
