On Saturday 13th March 2010 CHaOS will take over the zoology labs of the University of Cambridge for a day for Crash, Bang, Squelch!, inviting in over 2000 visitors to see lots of exciting hands-on experiments from all areas of science.

The event is open from 10am-4pm, and is absolutely free. Drop in any time, there's no need to book in advance, although in busy periods timed tickets may by issued for later in the day (we might run out of tickets before the end of the day, so get here early to avoid disappointment).
More information, including details about the exciting talks we're running next door to CBS!, will appear here soon.

We're currently in the process of developing a brand new website, with lots of updated information about CHaOS and the events we run.

(NB: We're still keeping this site up to date as well at the moment).

Crash, Bang, Squelch! is the biggest single event of the CHaOS year, bringing over 50 experiments into one place, for more than 2000 visitors to see during the day. This year CBS! is on Saturday 14th March, and is open to the public from 10am-4pm. Like all CHaOS public events, CBS! is absolutely free.
Come along to see lots of exciting hands-on science experiments, have go yourself and find out lots about what is going on. Our experiments will show you why hot air balloons stay up, what happens when you split water in half, how your lungs work, and much, much more...
This year, we will also be running some talks in a lecture theatre next door to CBS!, with lots of exciting experiments that are just too big to fit into the normal lab! See below for talk times, pre-booking is not required, just show up and be amazed.
Note that CBS! is usually very popular, and during busy periods we are likely to be preventing long queues by issuing timed tickets for later in the day. Last year we ran out of tickets at around 2.30pm, so get here early to avoid disappointment!
If you're a student in Cambridge and are interested in helping out with CBS, then you might like to visit our Demonstrator sign-up page.
The venue is fully accessible to those with mobility difficulties, and there are toilets on site. See here for a map of the location.
