Radio-frequency (RF) cavities are the foundation of most modern particle accelerators. Come and play an interactive game in which you can fine-tune virtual RF cavities to keep a particle beam on track.

This show will introduce you to the evolution of the (anti-)universe. By learning about atoms, anti-atoms and the scientific method, you will help to solve the mystery of antimatter.

Come here to build and operate a detector that uses evaporated alcohol to make a "cloud" that can sense passing particles.

Plastic scintillator detectors give off light when hit by a particle. Come here to help assemble a small plastic scintillator detector and see it working. You'll also be able to see a replica of the scintillator detector that will be installed in the T2K neutrino experiment that is based in Japan.

Looking for a Lego set to put your building skills to the test? Look no further and try the CMS detector Lego model. 250 models will be given daily to children who take up the challenge.

Ready for some competition? Create your own particle detector using Lego bricks. Whether you are 4 or 94 years old (or somewhere in between), we look forward to seeing your design, construction and naming skills in action. Exciting prizes will be given out for the best designs.

Come and see presentations and explanations of the CAD (computer-aided design) and virtual-reality tools used at CERN, including the software needed to design and produce 3D models of the components of experiments at CERN.

Come to this visit point to learn how to recognize and care for a person in cardiac arrest, through a playful and interactive race.

Watch CERN's firefighters demonstrating their work at the Laboratory.
