Balloons are light, colourful, and exciting — but they are also fragile. They rise quickly, draw attention, and can disappear just as fast. That mix of excitement and risk has helped balloons float into everyday English. Balloon-inspired idioms often talk about sudden success, unrealistic hopes, or moments when excitement meets reality.
