The particles に (Ni) and で (De) can both be used to specify locations, but each serves a different purpose. If you ever wondered how they're different, or you've been using them without knowing the difference, this episode is for you! In this episode, Kanae and Rachel discuss the basic difference and illustrate it using examples and quizzes. They even talk about which particle to use to describe niche situations like "egging a house" or "dropping a phone in the toilet."
