We had an amazing talk on Monday evening by Dr Maria Pavlidou from The University of Birmingham Physics and Astronomy Department about extremes of temperature. She intrigued all of the audience, including 3 and 4 year olds, demonstrating and explaining about temperatures from absolute zero, -273 degrees C to 100 degrees C and even higher. Everyone loved the liquid nitrogen which was fascinating, especially when thrown on the floor and my favourite part was when the fresh leaves shattered after being soaked in the liquid nitrogen. The hovering magnet experiment used for trains, looked just out of a magic show, inspiring us all to go into the world of physics. We were given a real treat!
