Would you like to discover our exhibitions in a fun and interactive way? Try our treasure hunt, "On the Trail of Particles"!

Step into the shoes of CERN scientists

Your mission: follow their trail and uncover the secrets of our Universe. From the Big Bang to the high-energy collisions taking place deep beneath the Earth's surface, each clue will bring you closer to understanding the origins of everything around us. Stay curious, observe carefully, and trust your instincts… the Universe does not reveal its mysteries easily.

Answer 8 questions, with the answers hidden throughout the exhibitions—and sometimes beyond. Each correct answer will unlock the next step of your adventure.

To take part, all you need is a smartphone, an internet connection (or connect to the free CERN-Visitors Wi-Fi once you're here), your curiosity, and about 45 minutes of your time.
