Dr Tong took a pic of the interesting phenomenon he noticed when having a cup of milk tea.

Doing silly stuff seriously can be a source of happiness – ask the expert Dr Tong.

“I was having milk tea in a restaurant the other day, noting that when my drink evaporates at the surface, capillary action draws the liquid flow. Solid particles are brought to the edge of each tea droplet, forming holed patterns (corresponding to outlines of the droplets). Another interesting phenomenon is that when a drop of milk splashes into hot tea, the milk droplet occasionally levitates for one or two seconds due to the rising vapour, bounces then fuses into the tea. It’s really intriguing, I’ve witnessed it before.” These daily-life physical phenomena may seem boring, but do inspire physicists to make the next major discovery.

Headquartered in the Netherlands, WeTransfer is a well-known company offering file transfer services. As many as a billion files are reportedly transferred among 195 countries or regions via their platform. This June, the company announced its status as a certified B Corp – alongside over 3,000 corporates, they are recognised for their efforts in human resources (staff and customers), community and environment-relevant policies.

Originated from the US, B Corp is a much-discussed business model that emphasises both shareholder interests and multidimensional societal impact. Towards the end of last year, The Guardian also became the first mainstream media to be accredited.

Amid the pandemic, the global travel industry went through a silent spring and was forced to develop “inwards”. In May, the Baltic states became the first interconnected “travel bubble” within the European Union. While this has yet to be realised between Hong Kong and other regions, the “Hello Hong Kong. Holiday at home.” platform was launched in June to encourage “staycations”.

Indeed, most Hongkongers might be “coming home” to Japan and Taiwan every year, while seldom setting foot on the other side of the harbour or unfrequented corners of the territory. Social enterprise Walk In Hong Kong recently initiated a “Rewalking Hong Kong” series. Join these themed walking tours with special guests and celebrities, and get to know our city in a way you’ve never experienced before!

Those who can actually change the world are often seen as “unreasonable” by the mainstream society – wrote social innovation and sustainable development experts John Elkington and Pamela Hartigan in The Power of Unreasonable People: How Social Entrepreneurs Create Markets that Change the World.

Through lively stories, the authors shared the journeys, ways of thinking and strategies of several social entrepreneurs – how they overthrew existing industries, value chains and business models to create new markets, as a response to pressing social, economic and environmental issues.
