E = MC² Coffee T-Shirt | Funny Science & Coffee Graphic Tee | Comfort Colors Shirt

Einstein got us most of the way there—but every coffee drinker knows the formula could use one small revision. This playful twist on the world's most famous equation proves that real energy comes from milk and an unhealthy amount of coffee. Clean typography and subtle vintage distressing keep the design timeless, making it perfect for scientists, engineers, teachers, students, baristas, and anyone whose day doesn't officially begin until the first cup. Printed on a premium Comfort Colors garment-dyed tee, it's a smart conversation starter for caffeine-powered minds.
