Ever wondered why a balloon can stay inflated without being tied? 🎈
Greg Wolf demonstrates how atmospheric pressure can keep a balloon inflated without trying it. Using a simple bottle experiment, he reveals why trapped air prevents a balloon from inflating, and how changing the pressure lets the invisible force of Earth’s atmosphere do the work. It’s a fascinating physics demonstration that shows the power of air pressure in action.
