This is due to condensation. The cold surface of the bottle condenses the water vapor in the air (humidity) into liquid water.
A good experiment to try, when it's really cold outside, is to buy a bottle of bubbles. Blow the bubbles outside and see what happens to them.
Condensation - The surface of the bottle and the air just above it will be cool enough to allow condensation of the water vapor in the air onto the bottle's surface.
Your water bottle contains some air along with the water. The air is warm when you leave the house but it cools off outside. Cooling air contracts. Since the water bottle is sealed air-tight, no new air can get in. The contracting cooling air inside the bottle exerts less internal pressure on the bottle, so the external pressure which remains constant (24 pounds per square inch) will then partially collapse the bottle.
You sshouldnt but, it could be cold and since cold= freezy it would be easier
Yes! If you heat a bottle with hot water, the balloon would grow bigger and bigger while if you put it under cold water, you would find out that the balloon became deflated again.
because it is hot outside so the bottle sweats as it absorbs heat
When a cold water bottle is placed on a warmer surface, such as a bench, the air around the bottle cools down and cannot hold as much moisture, causing condensation to form on the outside of the bottle. This moisture then transfers to the bench, leaving a ring of moisture.
Yes, it is bad. While cold it will not cure properly and you may just end up with a jellified mess.
It would be advised if you do not want to get cold.
That would be a good idea, especially if your house does not get much sunlight. And if it's wintertime, and cold outside, then I would definitely leave the light on.

You can leave your kids outside in the snow for a while to play depending on the temperature and their age. A good way to make sure they're safe playing in the cold is to make sure they're dressed as warmly as possible.
sometimes not in cold weather
Not exactly.The water that appears on the outside of the icy bottle is condensation of the water vapor in the air around the bottle. The cold temperature of the ice in the bottle causes the condensation. There are lots of water molecules in air -- there is more water in the air on a humid day then on a hot dry day, but there is always some water in the air. When air is cooled by coming in contact with the icy bottle, it condenses, and goes from being a gas to being a liquid (just like how steam turns back into water when it cools). It is the condensed water from the air that makes the outside of the bottle wet.If a cold bottle was in air that had no water vapor in it (unlikely except in a laboratory), then it would not get wet.

leave it outside
it causes condensation
