From the science of seeing to spies and seaweed, this series of short talks has something for everyone! Join CHaOS’s enthusiastic volunteers to discover some jaw-dropping science in these sessions, with a live stream of the talk and the chance to ask your questions straight to the speaker. Plus, you can try it all for yourself at home with the brand-new Experiment Files we’ve designed to accompany these talks!

Choose from seven different talks over three separate days and tune in to a live stream of the talk from our volunteers, who will then run a Q&A session in real time! There will be quizzes and polls, and an introduction from the speakers. The talks themselves will last 25 minutes, with up to 15 minutes  for the Q&A session.

Take a look at the relevant Experiment Files here, and find our YouTube channel here - you can see some examples of talks from previous years on our channel, too!

For a full list of talks, visit here! We're covering everything from the physics of rollercoasters to the lives of stars!
