On the 2nd of Feburary Doctor Mike Watkinson came into class 5AD. He is a scientist who works at Queen Marys University of Biology. He came into our class to show us science on solids, liquids and gases, which our year was learning about. Mike showed us tricks with liquid nitrogen. The whole room fell silent as he stuck his hand into the liqiud nitrogen. He froze flowers and bananas by putting them into the liquid nitrogen, and then smashed them with a hammer. After that his assistant Debs brought him an egg with a frying pan. He made the egg stick to the pan. At the very end he made ice cream using custard and liquid nitrogen. We had a great tim and hope they come again.
