Let's say that you take a plastic 1-liter soda bottle, empty out the soft drink it contains, put the cap back on it (so you have a sealed bottle full of air), tie a string around it like you would a balloon, and dive down to the bottom of the deep end of a swimming pool with it. Since the bottle is full of air, you can imagine it will have a strong desire to rise to the surface. You can sit on the bottom of the pool with it, holding the string, and it will act just like a helium balloon does in air. If you let go of the string the bottle will quickly rise to the surface of the water.
The reason that this soda bottle "balloon" wants to rise in the water is because water is a fluid and the 1-liter bottle is displacing one liter of that fluid. The bottle and the air in it weigh perhaps an ounce at most (1 liter of air weighs about a gram, and the bottle is very light as well). The liter of water it displaces, however, weights about 1,000 grams (2.2 pounds or so). Because the weight of the bottle and its air is less than the weight of the water it displaces, the bottle floats. This is the law of buoyancy.
Another way is the way a hot air balloon works. Put a gas fire almost in the balloon. The fire puts really hot air in the balloon. The material the balloon is made of keeps the hot air in. the balloon rises because hot rises. the temperature must be a certain amount higher then the air out side depending on the load.

What is aeronotical engeneering?
Aeronautical Engineering is the study of the principles and engineering of flight. From Balloons up to Spacecraft.
What is aerostat radar?
Aerostat radar is a low-level surveillance system that uses aerostats (moored balloons) as radar platforms.
Why do balloons fly at low altitudes?
Thy are held up by gas that is lighter than air. The hgher you go, the less dense air gets and therefore the less the difference between the gas being used to hold the balloon aloft and the air outside. They can therefore only go so high. Also, most balloons are not pressurised therefore the people fying in them would pass out for lack of oxygen if they went much above 10,000feet
What things were invented between 1750-1900?
Lots of things were invented during the industrial revolution but here are a few: Steam engines Canals Factories Hot air balloons Vaccines Telephone
How do government balloons work?
Government balloons are just like normal balloons except for the fact that they are used for government purposes. The government will use hot air balloons to transport military supplies, carry weapons, and to travel.
How does radar system work?
because of balloons and man mad
What are different types of water balloons?
there are the ones that work and the ones that don't
What is the relationship between air and balloons?
This relationship between the temperature and volume of a gas, which became known as Charles' law, provides an explanation of how hot-air balloons work
Where can one find personalized birthday balloons?
Personalized birthday balloons can be found at Party City, Fast Balloons, Balloons Tomorrow, Zoom Balloon and 1-800-Balloons. Personalized balloons at Party City can range from $3.99 to $9.99.
How many types of balloons are there?
There are a variety of balloons available, including latex balloons, foil (mylar) balloons, helium balloons, air-filled balloons, water balloons, and LED light-up balloons. Each type serves different purposes, from decorations to entertainment.
What kinds of balloons are there?
hot air balloons, colorful ones what kind of simple quesion is this!
How do weather balloons work to gather atmospheric data?
Weather balloons work by carrying instruments called radiosondes that measure various atmospheric parameters such as temperature, humidity, and pressure as they ascend through the atmosphere. The balloons are filled with helium or hydrogen gas, which causes them to rise and reach high altitudes where the data can be collected and transmitted back to the ground station.
How do bell jar lungs work?
The bell jar is an airtight space. When the rubber diaphragram is pulled the volume of the space increases and air rushes into fill it, therefore expanding the balloons. When the diaphragram is released the volume of the space dcreases and the air in the balloons is pushed out. The balloons deflate.
How do water balloon slingshots work?
They don't. Try filing the balloons with mashed potatoes instead.
What gases are used in hot air balloons to make it work?
Heated air, like what you breath.
What types of balloons are there?
There are primarily two types of balloons based on the material they are made from: latex balloons, made from natural rubber, and foil balloons, made from metalized nylon. Latex balloons are affordable and biodegradable, while foil balloons are more durable and can hold helium for a longer period of time.
