A bright 13-year-old boy, named Thabo, took an interest in the construction of fireworks. He reached out to his father's friend, who is a science Professor, to assist him to build fireworks for Christmas. Thabo and the Professor built a firework rocket in Thabo's home backyard and launched it to test their creation. The rocket soared at excessive speed to a height of 220 meters, erupted into flames and fell onto the thatched roof of a lapa at a nearby tavern. The lapa burnt down. Can the standard negligence test, as it is usually stated in South African case law, be applied to Thabo and the Professor, or must the negligence test be adapted when applied to Thabo and the Professor respectively? Discuss in detail, with reference to relevant case law.
