Our students participated in the 58th Joint School Science Exhibition (Final Round), they demonstrated their product to the public from 21 - 27 Aug 2025 at the Hong Kong Central Library. Students utilized ultrasound to create stationary waves and levitated small objects in the air. Through manipulating the phase of the ultrasound, the objects were made to move along a path. The technique could be applied in small objects delivery in low-altitude airspace, echoing the development of low-altitude economy suggested by the government.

The Exhibition was successful and thank you very much for your support!
