 What I need:
A bowl
A balloon
Ice cubes
Hot water
An empty soda bottle
 What I do-1:
I place an empty soda bottle in a bowl of ice cubes. When the bottle
becomes cold, I take out the bottle from the ice bowl and slip a
deflated balloon over the neck of the bottle.
What I observe:

 What I do-2:
After the bottle has returned to room temperature, I place it in a bowl
of hot water.

The question that occurs to me:
Why did the balloon not show any change when the bottle was cold and get
inflated when placed in hot water?
