Crash, Bang, Squelch! 2011

Crash, Bang, Squelch! 2011 will be happening on Saturday 19th March 2011 (the first day after the end of Lent Term).

*** Waiting list now in operation! (From Thursday 10th February)***

We've had so many offers of help now that we're warning people that we may not have space for further volunteers. Once experiment allocations are confirmed for existing volunteers in the next week or so we'll finalise how many spaces remain. However, we do seem to have fewer Chemists and Physicists, so if you're prepared to demonstrate these experiments we might be able to suqeeze you in!

How to sign up

More about CHaOS and Crash, Bang, Squelch!

**What is CHaOS?** 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. We're run by an enthusiastic student committee and get help running our events from lots of enthusiastic undergraduate and postgraduate demonstrators.

**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 (right next to the whale) on Saturday 19th March 2011. 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 19th March is after the end of lectures, so you can have great 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 after the event for all those who help!

**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, 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. We'll also run several briefing sessions just before the event so you know exactly how everything will work on the day.

**Sounds great! How do I sign up?** The sign up page is linked at the top of this page. You will be able to select which experiments you want to do before the event, and there's lots of other information about CHaOS and the experiments on the rest of our demonstrator website (http://www.chaosscience.org.uk/demonstrator)- please have a look to find out what we do! Also, why not get your friends to sign up too?

**Questions?** If you've got any questions about Crash Bang Squelch!, or about CHaOS generally, please get in touch with us at contact@chaosscience.org.uk.

[Note: In previous years people have confused Crash, Bang, Squelch! and other Science Festival events, some of which also happen on Saturday 19th 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!]
