Question

Why the balloons come closer on blowing air
Answers

Answer 1

Answer:

This is because the high pressure air in the balloon pushes outward harder than the low pressure air in the bottle. The air in the balloon pushes out against the walls, keeping it inflated. When the hole is unplugged, air flows back into the bottle.

Answer 2

Balloons come closer on blowing air because:-

By blowing air forcefully between the balloons you created an area of low pressure. ... The air pressure between the balloons decreased in comparison with the air pressure around the rest of the balloons. Because higher pressure pushes toward lower pressure the balloons were pushed toward each other.
