simple! We can use glass bottles because it can be recycled
Ballons are made of an elastic plastic while a bottle in a harder plastic
Bottle caps are made not out of PET plastic because that would make the separation from the bottle imposible, PET does not float, so the caps have to be HDPE, PP or other plastic that is less dense than water, thus makin the separation process posible when the bottles are recycled.
The imitation is more marked by something other than the plastic cap of the bottle; the label on the neck should be embossed. Johnnie Walker black label is the most popularly counterfeited liquor.
Since air is less dense than water, the air pushes the bottle upward. The water filled bottle would sink because the density is greater than water.
Metal is a good conductor of heat, so it draws heat away from your skin faster than other materials like glass or plastic. This rapid heat transfer makes metal objects feel colder to the touch even when they are at the same temperature as a bottle.
A plastic always sink in oil like a plastic bottle will always float in oil.
it should if you have the plastic piece that holds the ipod still but other than that it should definitely work
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.
you can if you want to, but unfortunately it is very bad for your body. If you use a plastic bottle too much the chemicals and plastic that is a part of your bottle start to come off and into your water, which you drink. A better alternative than re using your plastic bottle, would be to go to Earth Fare or a place like that, and by a bottle that says BPA free.
As long as you're not the sort of person who thinks that you should test how far it will go, than yes. Not only is it durable in situations that you would use it, it is also more ecologically friendly in comparison to a plastic water bottle.
Why plastic is more dangerous... than what? Your question isn't complete, however, I can still give you a reason why plastic is more dangerous than metal. (In water bottle form.) Plastic is more dangerous than metal in water bottle form because when plastic heats up (like say it's left in a hot car for a long time) it releases a chemical called Bisphenol A (BPA) into the water or whatever is in your water bottle. This is potentially harmful. Metal does not release this kind of chemical. I hope I helped!! :)
Beer Is Stored In A Glass Bottle Because, If You Stored It In Plastic You Could Taste A Plastic Taste Off It And Also Glass Get Colder Quiker Than Plastic.
