This mug celebrates the most famous equation in rocketry: the Tsiolkovsky Rocket Equation. One side features the equation itself, while the other illustrates the true challenge of spaceflight—the alarming amount of coffee required as your delta-v ambitions grow. Perfect for rocket scientists and aspiring rocket scientists alike.
Mugs are dishwasher (top rack preferred) and microwave safe, but please don't stick it in an air fryer.
