Physical science plays an essential role in our daily lives, ranging from our smartphones to transportation, electricity and even medical health. In encouraging our potential teenagers in Hong Kong to discover and share the wonders of physical science with the public, the Department of Applied Physics at the Hong Kong Polytechnic University organizes the PolyU Physics Short Video Competition 2023. The competition aims at not only fostering your initiatives in exploring knowledge of theoretical physics in your daily lives with the development of critical thinking skills, but also lending your helping hands to spark public interest in physical science.

The competition is open to all full-time secondary school students in Hong Kong. Interested students are required to create short videos (maximum 5 minutes) that explain and describe a complicated physics-related scientific concept or phenomenon in a creative, accurate, engaging and understandable way. We don't care if you are dancing, acting, or using props to get your point across – as long as you are using your scientific smarts and creativity to make it happen! So, get your cameras ready, put on your thinking caps, and let's see what you can do!
