Cambridge Science Fair

Some 300 events all held in Cambridge in March. Some are drop-in; some need to be pre-booked, and they can book up fast.

Really aimed at teenagers, looking to find out more about science, though kind of interesting to anyone interested in science. It is run by the university and so the science and the researchers are world class.

The day I went to was very busy, though well worth the effort.
