Cambridge Hands-On Science (CHaOS)

Hello, and welcome to CHaOS!

**What is CHaOS?**
If you don’t know who we are, Cambridge Hands On Science (aka CHaOS) is a student society which aims to show children and families that science can be fun and exciting, and something that they can understand.

**CHaOS need student volunteers**
We’re now recruiting volunteers for our biggest annual event, “Crash, Bang, Squelch!”- this a huge hands on science day that we run during the Cambridge Science Festival. We’ll be taking over the Zoology Department in the New Museums site (on the right when you enter through the arch) on Saturday 14th March 2015. We’ll have lots of own exciting experiments, and we’ll need lots of enthusiastic student volunteers to help demonstrate them to the public. Saturday 14th March is after the end of lectures, so you can have fun helping out without worrying about work.

**What exactly does it involve?**
We’ve got a huge number of hands-on experiments that we’ve designed to demonstrate interesting scientific principles. You might find yourself demonstrating how bridges stay up, why some things glow in the dark or even introducing children to Boris the skeleton. The ideas are simple, but with enthusiastic and interested demonstrators we can show children that science isn’t a ‘boring’ subject.

You can choose to demonstrate in the morning or afternoon, and if you choose to do the whole day we’ll even provide you with a *free lunch (whoever said there was no such thing?). Even better, there is a *free party* in the evening for all the demonstrators.

**Sounds great! How do I sign up?**
The sign up page is on our website at You will be able to select which experiments you want to do after your initial signup, and there’s lots of other information about CHaOS and the experiments on our demonstrator website ( please have a look to find out what we do! Also, why not get your friends to sign up 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 Crash Bang Squelch!, or about CHaOS generally, please get in touch with us at

[Note: In previous years people have confused Crash, Bang, Squelch! and other Science Festival events, some of which also happen on Saturday 14th March… Obviously we think Crash, Bang, Squelch! is the most fun, but it makes everyone’s life easier if you make sure you’re not double booked!]

Thanks for reading all the way to the bottom- we hope to see you at a CHaOS event soon!
