We love escape rooms, and it's awesome how the industry has evolved to provide ever more impressive and immersive experiences. Some of the top escape rooms today are huge warehouse-spanning installations with six-figure budgets. But what if they didn't have to be? Last year, our team had the opportunity to build a pop-up escape room. We wanted to match the creative ambition and capacity for wonder demonstrated by the biggest and best escape rooms in the world; implemented with the scrappy enthusiasm, inherent impermanence, and modest budget of an amateur theatre production. What we built turned out to be a real dream. Over our five-month run, our core team (gradually bolstered by dozens more volunteers) provided a unique and delightful experience for over six hundred visitors of all ages, including twenty children, two babies, and one dog. We received amazing feedback, tremendously kind reviews, and hugely encouraging industry recognition. In this talk we'll cover how we turned our ideas into reality, what went to plan, what went wrong, and what we learned. Most importantly, we hope to show what is possible and perhaps inspire other projects, because we'd love to see more escape rooms in the world.
