No, Not at all because they are made up of Bisphenol, a chemical, which is really harmful to health
will a plastic bottle remain the same in the next fifteen years
The plastic drink bottle feels warmer than a metal can because the metal can has a higher thermal conductivity compared to the plastic drink bottle. Thermal conductivity is the property of a substance to conduct heat, and the metal can, being made of metal, has a much higher ability to conduct heat compared with the plastic bottle. This means that when you touch the metal can, it draws out your own body heat faster than than when you touch the plastic bottle, so the can feels cooler.
Crushing a plastic bottle is a physical change, not a physical reaction. This is because the plastic's chemical composition remains the same even though its physical form has changed.
No, not in theory. However, if the oral hygeine of the person drinking from the bottle is poor, it is possible to leave harmful bacteria on the mouth of the bottle. This could be a problem if multiple people drink from the same bottle.
Basically, its from the suction from the person drinking it. actually its form the external air pressure crushing it as you remove air from the inside, if you leave a small gap as you smoke this will not happen. it is important to remember you are only removing the equalising air form the bottle, it is the inequality that makes vacuumed bottles crush and shaken soda bottles expand as they have higher air prssure than the outside, check you physics mate
It is generally safe for a baby to drink from the same bottle of breastmilk twice, as long as the milk has been stored properly and the bottle has been cleaned and sanitized between feedings. However, it is important to follow proper guidelines for storing and handling breastmilk to ensure its safety for the baby.
A PET plastic bottle (number 1) will last for months, probably years. Just make sure you wash it with warm water and detergent to prevent bacteria growth, especially the mouthpiece. That's all you have to worry about.

All plastic can be recycled, so, yes, plastic bottle tops can be recycled.But maybe your town or city doesn't recycle them. So check.Bottle tops are usually made from Plastic #5 and the bottles are usually made from Plastic #1. So they have to be separated.Take the bottle caps OFF and then recycle both the cap and the bottle.A:Plastic recycling is very complex and requires that the same types of plastics be separated from other types so as to not ruin the meld. Also, just because plastic has the "chasing arrows" doesn't mean that they are recyclable in your area. This just tells the trained eye what type of plastic they are. The tops of the water bottles are often made from a plastic resin which is obviously different from the plastic used to make the bottle. When plastic is recycled and melted down it is crucial that all the plastic is the same type. If different plastics gets mixed into a batch, the batch is downgraded.To be safe, I would at minimum remove the plastic bottle cap from the bottle to make the recycling process easier.See the link below.Yes indeed, they should be recycled. They are a different kind of plastic, so they should not be left on the bottles.I have as yet only found one company that recycles plastic bottle caps. Aveda is a beauty care product company and is accepting plastic bottle caps that they have recyled into new caps and containers for their products. See their web site: http://aveda.aveda.com/aboutaveda/caps.asp I would love to hear of any other locations for recycling bottle caps.
In the first place the water in the bottle would keep the temperature of the plastic down preventing it from burning and leaking, The same as you would do by boiling water over a flame in a paper cup, However the water in the bottle would heat up and eventually the pressure inside the bottle would burst it like a balloon.
no this is just a rumor but make sure you are switching bottles every now and then because after a long period of time toxins from the plastic can get into your water so it is fine as long as you do not use the same bottle over a long period of time
