| Fully animated 'Escaping of air from balloon' shows how molecular diffusion takes place, what appears as a solid object is in fact not so, especially if we zoom in to molecular level. The deflating of a balloon over a period of time is a result of this effect.

This animation has audio.
Category : Diffusion
Type : Animation with sound
Animation Type : Regular
Total animation length: 12 minute
The animation has the following sections: Balloon and its structure
Air Escaping out of balloon
Common Questions
- Myth: The pressure inside a bigger balloon is higher
- Science Project 1: Interconnecting two balloons
- Why it is difficult to start blowing a balloon?
- Why do balloons filled with helium deflate faster?
- Can a balloon inflate when kept for some days?
- Science Project 2 - Balloon inflates when kept in air
- Myth: Balloon will deflate faster in a cold room

| Polymer chains play a big role in diffusion of air or helium out of a balloon. |
|
|
|
These are questions that are answered in detailed, there are some science projects pertaining to diffusion, common myths about balloon and questions on inflation and deflation of a balloon. |
|
It is difficult to realize that the escaping of air from balloon is a function of diffusion, diffusion normally occurs through porous membranes but a balloon looks solid, how is it possible for diffusion to occur. A balloon is however made up of polymer chains. These chains have spaces between them to make them porous.
