yes it can because the plastic will somehow change the water and you can get sick from drinking it
Ayraayra: If you have taken a drink of the water the bacteria inside your mouth gets on the opening of the bottle, it then can grow since it has a warm wet and dark place to stay.
The water bottle may be sealed tightly, making it difficult to open.
Lift the empty bottle out of the water cooler and move out of the way. Open the seal of the full bottle, while it is sitting on something. Lift the full bottle and flip over quickly, so that the narrow end (where you took off the sealed cap) fits in the opening of the cooler. Adjust to make sure it is centered and balanced on the cooler. Enjoy

send an astronaut with a bottle of water and open it in space
To open a hard-to-open bottle, you can try using a rubber grip or a towel for better grip, running the bottle under hot water to expand the cap, or using a bottle opener or a pair of pliers for extra leverage.
Nothing. The bottle is now truly empty.
Unless you carefully read the label on the bottle, you will only know whether the bottle contains spring or sparkling water, once you open the bottle. If on opening the bottle there is a hiss, it contains a sparkling water - not flat spring water.
Bubbles in your water bottle are likely caused by gases dissolved in the water, such as carbon dioxide. When you open the bottle, the pressure decreases, causing the gases to come out of solution and form bubbles.
Try to make your fingers very strong then open it with your fingers and look at it when you open it.
in closed water bottle system preasure generates due to vaporization of water. but this process of vaporization stopes when equilibrium is acheved for a perticular temperature. but in open bottle system equilibrium is NT acheved and hence vapour preasure can NT be measured.
When a tightly capped bottle of water is kept in the open sunlight, it heats up and the water inside starts to evaporate. The evaporation process releases gases trapped in the water, creating bubbles around the bottle. The heat from the sunlight accelerates this process.
As soon as someones mouth touches the bottle, bacteria is present. Allowed to sit for a couple of days, the water will "foul"...(develop an unfresh taste). Refridgeration helps delay this fouling process whilst direct sunlight and heat will hasten it. Bottles that have been LEFT OPEN for days or weeks may have additional contaminants introduced to them, and, if ingested may cause mild diarrhea. Keeping open bottles "cool" will cause no problems.
