Can you really launch marshmallows out of a vacuum cleaner, make rockets from everyday household items, or launch teddy bears using liquid nitrogen?
The curiosity drew close to 200 people to Sci-Enza Science Centre in the Faculty of Natural and Agricultural Sciences late in 2022 to see Dr Graham Walker's Science Circus live! Dr Graham Walker is from the Australian National University, working specifically at the university's Centre for the Public Awareness of Science.
Dr Graham Walker has been performing science shows for almost three decades to demystify the myths that science is difficult and complex or only happens in laboratories. He excites and leaves the audience intrigued using simple materials you can get in your kitchen, from a vacuum cleaner demonstrating the relationship between time and velocity to the bicarbonate of soda rockets for teaching about Newton's Third Law.
The 'Science Circus' was made possible through the support and sponsorship of the Australian Government Direct Aid Program through the Australian High Commission South Africa.
