An EpiPen seems simple: just one step to administer a life-saving dose of adrenaline. This video reveals the hidden genius behind that simplicity, using a dissected pen and a large-scale model to explain the three distinct, battery-free mechanisms that work in sequence. Discover the clever engineering that fires the needle, delivers the dose, and automatically makes the device safe after use.
