Find out more about Crash, Bang, Squelch! 2019 here.

Crash, Bang, Squelch! (CBS!) is the biggest single event of the CHaOS year, taking place as part of the Cambridge Science Festival. For Crash, Bang, Squelch! CHaOS has over 50 experiments in one place, for more than 2000 visitors to see during the day. In 2019, CBS! is taking place on Saturday 16h March 2019, and is open to the public from 10am-5pm. Like all CHaOS public events, CBS! is absolutely free.

Come along to Crash, Bang, Squelch! to see lots of exciting hands-on science experiments! You can have go yourself and find out lots about why things work they way they do!

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...

We also run a series of 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.

Times are listed on this year's event page: pre-booking is strongly recommended as there will only be limited tickets on the day!

Please note that CBS! is usually very popular - in 2019 we will be offering pre-booking for timed tickets - booking will open in early February.

Now that the building work has finished, all of our activities are fully accessible. A map of the location is shown to the left.

In 2018 CHaOS had a fantastic series of events at the Science Festival, with busy events on both of the main weekends. On Saturday 17th March, 'Crash, Bang, Squelch!' was full to capacity all day, and all 8 brilliant talks in the lecture theatre next door were also very well attended.
