This science teacher in Terrigal, New South Wales, demonstrates the exponential growth of the COVID-19 virus by using bread and a toaster.
Jacob Strickling uses the toasting of bread as an analogy to the development and spreading of COVID-19 during this pandemic.
The teacher highlights the importance of social distancing as for the first few intervals the bread remains white yet in this analogy symptoms can still be spread.
As time goes on the bread becomes more and more toasted indicating more people becoming infected by the virus, as shown on Jacob's graph.
