The video tutorial explains the rapid self-duplication of bacteria in a Petri dish using an exponential growth model. It demonstrates how to calculate the number of bacteria after 120 minutes using the function B(t) = 10 * 2^(t/12). The tutorial walks through the calculation process, verifies the result, and concludes with the final count of bacteria, which is 10,240.
