because when you breath in the balloon then the balloon goes biger and and when you let go of the balloon then the air comes out its exactly like our breathing system
The model of lungs with a balloon demonstrates how the lungs expand and contract during the breathing process. When the balloon is inflated, it represents the lungs filling with air during inhalation. When the balloon deflates, it shows the lungs releasing air during exhalation. This model helps visualize how the lungs work to take in oxygen and remove carbon dioxide from the body.
A balloon pump works by pushing air into the balloon through a narrow nozzle. By squeezing the handle, the pump creates pressure that forces air to flow into the balloon, inflating it. The one-way valve on the pump prevents air from escaping and maintains the balloon's inflation.
It is called a balloon pump.
because your reserve air is been use up little by little and so have difficulties in breathing the more you blow the balloon.
with a bicycle pump
A demonstration of pressure could be done best with a balloon and a pump. By inflating the balloon using the pump, the increasing pressure inside the balloon can be observed by its expansion. This can help illustrate how pressure can cause a volume to change.

To blow up a big balloon without a pump, you can simply use your mouth to blow air into the balloon. Hold the neck of the balloon securely while blowing into it to inflate it. It may take a bit more effort and time compared to using a pump, but it is a simple and effective method.
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
To inflate a balloon, you can blow air into it by using your lungs to push air out of your mouth and into the balloon. Alternatively, you can use a pump to push air into the balloon.
There are several techniques to using a balloon pump correctly. The safest way is to make sure one has a firm grip of the pump and make sure that the ballon is in complete contact with the nozzle.
