The balloon may lose some air during that half hour.Also, at a lower temperature, the remaining air uses less space.
at least -18 degrees
Assuming you are attempting to puncture a balloon and keep it intact, I would reccomend puncturing the balloon near the knot, where the rubber is thick and not streched out. If you are trying to pop the balloon, then I would puncture the balloon where the rubber is thinnest.

The answers depend on the sizes of these objects.
If plants are put into a freezer, they freeze.

No, the balloon with the least amount of air will not necessarily go out faster. Factors such as wind speed and direction, temperature, and weight of the balloon will also affect the rate at which the balloon goes out.
Ballon means either 'balloon' (a hot-air balloon) or 'ball' (at least the size of the handball one).

You can store it in the freezer in a large ziplock freezer bag, to prevent weevils from getting into it. It should be fine for at least a year; I've had some ground flax in the freezer for at least 2 years that still tastes fine.
Any chest style freezer is stable enough that tipping over will not be a concern. anonymous@oola.com
For at least six hours before balloon valvuloplasty, the patient will have to avoid eating or drinking anything
The smallest commercially (easily) available steel rod is about 0.014" diameter.

A balloon is less dense than an apple because it is filled with air, which has a much lower density than the solid matter that makes up an apple.
