Balloons fly because they are filled with something very light, like helium or hot air! 🌬️
When a balloon is filled with helium, it's lighter than the air around it, so it floats up, up, up into the sky! 🎈
Just like how a bubble floats in the air, balloons do the same!
Balloons fly because of something called buoyancy! 🎈
When a balloon is filled with helium or hot air, it becomes lighter than the air around it. The air outside pushes the balloon up, making it float!
Helium is a special gas that's much lighter than the air we breathe. Hot air also rises because it's less dense than cold air.
That's why birthday balloons float, and hot air balloons can carry people high in the sky!
Balloons fly due to the principles of buoyancy and gas density. 🎈
Helium balloons float because helium is less dense than the nitrogen and oxygen in the air. This creates an upward force called lift.
Hot air balloons work similarly: when air is heated, its molecules move faster and spread out, making it less dense than cooler air. The balloon rises because the warmer air inside is lighter than the cooler air outside.
The science behind this is called Archimedes' Principle, which states that any object in a fluid (like air) is pushed upward by a force equal to the weight of the displaced fluid.
