Is it safe to use PET bottles for storing drinking water.what does triangle & number on its bottom signifies?

The symbols on the bottom indicate the type of plastic. This information is (theoretically) used for recycling purposes. Not all plastics can be dumped togeter for recycling.\n\nIf the bottle hasn't been used there shouldn't be a problem. I would not recommend a used bottle unless it has been boiled, and personally wouldn't use it even then.

Yes, it is healthy to drink 1.5 l water in the morning.\nkidney's would benefit on the contrary to getting damaged as they will process a relatively pure and dilute blood, which is otherwise more concentrated and impure because of other elements from food etc.\n\nI did try this method for around 6 months and got benefitted. I would also suggest you to use copper vessel to store water overnight that you drink in the morning.

Can this realy be true that there is an antifreeeze chemical for animal drinking water ?\nI doubt it. I am not a farmer, but I know that they simply keep the animal drinking vessels protected from the weather.\n\nI admit to not being an expert.

I've been using a plastic water bottle again and again (for drinking water from), and I've been fine, however if you are worried, then wash it out properly between uses (as in with detergent and hot water).  We use glasses again and again, and this is considered ok, so why not plastic water bottles?

I just watched a news special recently on nbc re: freezing water bottles.\n\nI found this article that I copied and pasted.  But I have also read on other websites that it does not.\n\n"DIOXINS Carcinogens cause cancer. Especially breast cancer. Don't freeze your plastic water bottles with water as this also releases dioxins in the plastic. Dr. Edward Fujimoto from Castle Hospital was on a TV program explaining this health hazard. He is the manager of the Wellness Program at the hospital. He was talking about dioxins and how bad they are for us. He said that we should not be heating our food in the microwave using plastic containers. This applies to foods that contain fat. He said that the combination of fat, high heat and plastics releases dioxins into the food and ultimately into the cells of the body. Dioxins are carcinogens and highly toxic to the cells of our bodies.\n\nThen I found this article from John Hopkins that says it does not\n\n\nBALTIMORE -- Johns Hopkins researchers have responded to an e-mail warning against freezing water bottles. A recent e-mail hoax claims Hopkins scientists warned people that freezing plastic bottles releases dioxins into the water. But the researchers say that's entirely false -- they said freezing plastic water bottles will not expose people to dangerous chemicals.\n\nResults | Disclaimer \n \nAccording to Dr. Rolf Halden, of the Johns Hopkins Bloomberg School of Public Health, freezing actually works against the release of chemicals and scientists are not even sure plastics contain dioxins. \nHowever, Halden does warn that another group of chemicals that are used to make plastic less brittle can be released if you place them in hot water or heat them in the microwave.\n\nBut Halden stresses that people should not be afraid of drinking water and that "you are more likely to suffer from the adverse effects of dehydration than from the miniscule amounts of chemical contaminants present in your water supply."\n\nHe also said people should be more concerned about the quality of the water they drink more than the bottle from which they drink it. Although people tend to assume bottled water is the safest route, Halden said city water is much more highly regulated and monitored for quality.

or_try_this is correct.  It is dense, and a 30-inch column of mercury fits in a laboratory better than a 34-foot column of water.  It is stable and doesn't evaporate at room temperature.  Its thermal expansion can be compensated for, but it's usually small compared to the pressure differences it's measuring.  It looks scientific, too.

If you re-use the plastic bottles, you'd have to wash them in hot water.  Washing in hot water starts to break down the plastic.  (Just like cooking in plastic in the microwave eventually breaks the plastic down).  Just drinking from a new container doesn't hurt you.

There is no MSDS for drinking water.  If you are selling water, it is FDA or USDA labels you have to have.  Drinking bottles in a workplace do not require special labels, but a laminated label might work best.

Could you try the old idea of different types of liquid in a clear glass/plastic tube. Each has a different density, so the heaviest goes to the bottom, the lightest to the top? Cant remember the exact liquids to use, but something dense like oil, then baby oil, water, etc.....the tube can be shaken, but the liquids will always seperate out in layers......

Can you put the bottle in a zip-lock bag?  This might keep her from fooling around with it.  I personally, would not drink from the bottle if she handled it.

well,not all soft drink are safe.\nover sugarated.

i would assume it depends on the plastic.  But NaOH pellets are stored in HPDE (high density polyethylene) plastic containers.  So my thinking is if concentrated NaOH is stored in plastic than the liquid should also be able.

I don't know how true that one is.. but you can get sick from drinking straight from the can.  Who knows where the top of that can has been?  Sure rats could pee on it, and all kinds of other things.. I pour mine into a cup, or wash the top of the can just to be sure.

I looked at the barf bag on my plane and did not find any warnings restricting its use. I think all the restaurant doggie bags should switch to barf bags so they don't leak all over your purse and seat on the way home. Lets hear it for the multi-purpose barf bag.

The bottle is not vented.  If the bottle was vented at the top, all the water would flow out onto the floor.  Since it is not vented, a vacuum is created inside the bottle so the water stays in the bottle until the level in the bowl goes down far enough to uncover the mouth of the bottle and then it is vented until the level in the bowl fills up again to cover the mouth of the bottle back up.\n\nTry filling the sink with water...then dip a cup into the water in the sink and turn it upside down.  If you pull the cup up above the water level in the sink, the water will remain in the cup until the lip of the cup comes out of the water in the sink.  If you only let it stay out of the water for a split second, it may be possible to keep some of the water still in the cup.  The pet bowl works on this same principle.

It means that it is recyclable. The number indicates the type of plastic. The numbers are\n1 = Polyethylene terephthalate\n2 = High-density polyethylene\n3 = Polyvinyl chloride\n4 = Low density polyethylene\n5 = Polypropylene\n6 = Polystyrene\n7 = Any other plastics

have several cats.   both will drink out of the faucet, but prefer drinking out of the fish tank which they stand on top of and straddle (the fish have been know to come up and brush against their tongues, they have never tried to catch the fish).   one of mine likes to suck hair,   both want to sit on top of the compt (they both can't fit at same time so turns are taken).   one likes to sit in my lap while i type on comp resting her head on my hands as they go up and down (makes typing hard to say the least and if she decides she doesn't like it she makes me start messing up).   one likes to chew wool (and boxes),  i have a drawer with wool fragments (that she has made) she opens it and takes them out and plays with them.   the other,  i have to be careful since she wants to get in and lay in the refrigerator ( i once shut her in there, but now i know i am more careful),  this one also likes to open drawers and cabinets (i find her resting in them all the time)  needless to say when i come home it looks as if the place has been ransacked.   there is more, but will leave it at these.  i don't believe i have ever had a "normal" pet in my life,  and i like it that way.
