Are you faster than the LHC fast protection system? To protect the LHC in the event of a problem, the huge energy stored in the LHC particle beams must be discharged in less than a thousandth of a second. Test your reaction time and try to beat the LHC fast protection systems.

Join the CERN Fitness club and others on the Sustainable Dance Floor, which uses human movement as a source of energy. This kinetic energy is converted into electricity that powers the floor's LED lights. Through this process, the floor interacts with the dancers to involve them in an interactive energy experience.

Learn and practice cardiopulmonary resuscitation and other life-saving emergency techniques.

In this workshop, children can learn the basic principles of "unplugged programming" (6- to 8-year-old children) and robotics (9+ years old), be introduced to the components of computers through colouring (any age), find out about the LHC@Home volunteer computing platform (any age), and take a virtual tour of the Data Centre with virtual-reality goggles (any age).

Children and adults can head here to discover how stars are born, to find out how heavy they would be on different planets, to see the magnetic field around a magnet, and much more.

Take a selfie and let your friends and family know you were at CERN! With this poster of the CMS experiment as your background, people will think you actually visited the experiment.

Take a selfie and let your friends and family know you were at CERN! With this poster of the LHC as your background, people will think you were actually in the tunnel.

Witness and admire superconductivity in action in various demonstrations and have a go yourself. The demonstrations include a mini levitating train, a superconducting bicycle, a levitating scooter and many more.

Come and experience collisions of a different kind with members of CERN's very own Table Football club.

Come and explore the science behind the LHC and the Higgs boson with a tactile particle-accelerator model and immersive audio equipment.
