Signups for Mini Tour 2018 are now open!

CHaOS needs volunteers for the 2018 Winter Roadshow (also known as "Mini Tour")! To sign up, click here!

We're looking for scientists, engineers, medics and vets, mathematicians and computer scientists to join us at schools and public events around Cambridgeshire, where we'll get kids excited about science using fun, hands-on experiments! The roadshow will run from the 29th November to the 4th December, and you can join us for anything from just one day to the whole six days.

We'll be visiting:

  • Four Cambridgeshire schools (29th, 30th, 3rd, 4th)
  • Mill Road Winter Fair (Saturday 1st)
  • An Institute of Physics event (Sunday 2nd)

What exactly does it involve?

We've got lots of our favourite of hands-on experiments that we've designed to demonstrate interesting scientific principles. You might find yourself demonstrating how bridges stay up, pulling the DNA out of a kiwi, or even introducing children to Boris the friendly skeleton! The ideas are simple, but with enthusiastic and interested demonstrators we can show children that science isn't a 'boring' subject.

Each morning you join us, we'll pick you up from Cambridge and travel to the event, where you'll spend the day demonstrating your experiment to kids and getting them excited about science, and drop you back in the afternoon. You'll get a free lunch (and plenty of 'bounce' or snacks) too!

I've never done anything like this before.... will I be any good?

No experience is necessary, and every year we have loads of people who haven't done CHaOS before. If you're a scientist (including mathmos, vets, medics, engineers or compscis) you already know more than enough to demonstrate. The experiments have interesting and useful descriptions to explain the science and if you are unsure you can always ask one of the friendly committee members.


If you've got any questions about the event or about CHaOS generally, please get in touch with us at, or find us on Facebook!
