air
A water balloon is filled with water, and other balloons are filled with air or helium.
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
Density of any balloon depends on the material of the balloon and how much the balloon is filled.
I think a water balloon can be tossed if the water balloon is filled lightly. If the water balloon is filled heavily it might break before someone catches it. Also I did this before and I measured it and it was 74 feet and 5 inches exactly!
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
The balloon expands.
The balloon is filled with a gas.
A balloon filled with helium will likely deflate faster than a balloon filled with air because helium molecules are smaller and can escape through the balloon material more easily.
Putting an air-filled balloon in a refrigerator will cause it to shrink.
An invertebrate skeleton, such as a hydrostatic skeleton found in some soft-bodied animals like jellyfish and worms, is similar to a filled water balloon. This type of skeleton uses fluid pressure to provide support and structure to the body.
A balloon! When a balloon is filled with air or gas and becomes overinflated, it can pop suddenly.
The duration an air-filled balloon stays inflated can vary based on factors such as the quality of the balloon, temperature, and air pressure. Under normal conditions, an air-filled balloon can stay inflated for several days to a week before starting to deflate.
