How can we make the invisible visible? Explore how balls interact with a hidden structure to come up with your best model of what the invisible structure is and learn more about the Nature of Science!

A lot of phenomena scientists at CERN investigate are invisible to our eyes! For example, particles cannot be seen with the naked eye, and properties such as their mass, energy and charge can only be determined indirectly. How do scientists design clever experiments to understand things that aren’t visible?

Learn the basics of programming with Ozobot colour codes and discover how we use robots to help us work at CERN.

Mix your own slime and conduct experiments to find out how slimy detectors can help us to make invisible things visible.

A lot of phenomena scientists at CERN investigate are invisible! For example, elementary particles cannot be seen with the naked eye, and properties such as their mass, energy and electric charge can only be determined with the help of powerful research tools like particle detectors. In particle detectors, special materials make invisible properties of particles visible.
