HOT is working with Placeholder Interactive, a Maltese serious gaming start-up, to put together a tablet app aimed at young school-children, aged between 7 and 9, to teach them about the physics of light through the magic of play. This game creatively tackles standard topics such as light, shadows, and colours, and will also introduce the concept of radiation pressure – the fact that light pushes things – which underlies the science that makes the opto- and electro-mechanical systems of HOT possible. We are working hard on this game and hope to have a playable version made public very soon.
