In this episode of How Do You Not Know This?, Tony decides it’s time to truly test the show’s concept—with a deep dive into primary school science. What starts as a simple quiz on the water cycle quickly turns into chaos when Dom admits he doesn’t know what clouds are or that they produce rain. Daliso is convinced no one can be this clueless, but Dom keeps the surprises coming with confusion over evaporation, mammals vs reptiles, cold-blooded animals, and even basic human anatomy. This might set a record for the number of times you find yourself asking, how do you not know this?
