No. Swallowing air is not a good thing. It has zero benefits. Aerophagia is the term commonly heard when someone refers to swallowing too much air. If you swallow too much air it can cause (painful) intestinal cramps, abdominal pains, and you'll belch excessively. If only we could live in the Willy Wonka world.
It has air inside that makes it float.
When a balloon is blown up by mouth, it will not float, but fall to the ground. This is because the air inside is the same density as the air outside. For a balloon to float up into the air, it must be inflated with a gas that is lighter than air - such as helium.
density
Water has a higher density than air. Anything that is less dense will float. The tube's covering is not enough to make it sink when filled with air. That is also the reason that oil and water don't mix.
It's less dense then water, that's why it floats
Pumice has tiny air pockets to help it float in water.
to help it to float on water.
letting it float
once they die,all the air bubbles in them help them float to the top!
The wings of a bird help the bird float on air currents. That's why a bird doesn't have to flap the whole time. It can float or soar.
Helium is lighter than air, hence it will rise up in air, making things float up in the air.
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
things float in air because of density
No a train does not float in the air, no train does.
