Two engineering students brought to life an 18th-century mechanical volcano designed by Sir William Hamilton. The device uses light and movement to mimic volcanic eruptions.

Sir William Hamilton, the British ambassador to Naples and Sicily from 1765 to 1800, was fascinated by volcanology. In 1775, he imagined a mechanical artwork that could recreate the eruption of Italy's Mount Vesuvius. This idea blended artistic expression with mechanical design to capture the dramatic visual effects of a volcanic eruption.

The original concept was inspired by a watercolor painting called 'Night view of a current of lava' by British-Italian artist Pietro Fabris. The device was designed to use light and movement to mimic flowing lava and explosive bursts from Vesuvius. It remains unclear whether Hamilton ever built the mechanism, but a detailed sketch preserved in the Bordeaux Municipal Library served as the foundation for its modern recreation.

Dr. Richard Gillespie, Senior Curator at the University of Melbourne, launched the project and guided its development. He said it was fitting that after 250 years exactly, students had brought this dormant project to life. 'It is a wonderful piece of science communication. People around the world have always been fascinated by the immense power of volcanoes.'

Two engineering students at the University of Melbourne, Xinyu (Jasmine) Xu and Yuji (Andy) Zeng, spent three months building the device in The Creator Space student workshop. They used modern materials and technologies, including laser-cut timber and acrylic, programmable LED lighting, and electronic control systems, to adapt Hamilton's clockwork-based design for today's audience.

The students said they learned a lot from the project. Ms. Xu mentioned that she extended her skills in programming, soldering, and physics applications. Mr. Zeng said the experience gave him a deeper understanding of mechanical engineering in practice.

Research engineer Andrew Kogios supervised the students and highlighted their growth through the project. He said they developed hands-on problem-solving skills by selecting materials, 3D printing, troubleshooting electronics, and satisfying requirements. 'Experiences like these, supplementing their university studies, position them well for their future endeavors.'

The completed device is now on display at The Grand Tour exhibition at the University's Baillieu Library until June 28, 2026.
