Cambridge Science Festival - First Saturday

Today was the main day at the Cambridge Science Festival where there are Free lectures, drop-in sessions and hands-on sessions are on offer as museums and labs open their doors.             

We started the day with the engineering department making a fixed wing aircraft which uses the energy stored in a rubber strip to drive a propeller and pull it through the air (or at least that was the idea) :).  It was great fun and all the girls were able to make something that flew.            

 We then went to lecture about parasites before losing the big girls riding, which left P, E and me to visit the chemistry department where we made goo, extracted strawberry DNA, saw a superconductor, explored  density, and ate ice-cream made by liquid nitrogen amongst other things.
