The Global Indoor Lost and Found System, based on the satellite tracking global positioning programme, helps find things that often go missing at home.
Then there's the wind shear monitor that informs pilots of sudden changes in wind direction.
There is also the Shemir, a compact device which enables people who speak different languages to communicate.
These were just a few of the imaginative projects on display at the 31st Joint Schools Science Exhibition at the Hong Kong Science Museum in Tsim Sha Tsui.
