Can putting boiling water in a plastic bottle, waiting for it to cool, and then drinking it be dangerous?
The plastic gets soft, but the water never seems to taste too different. Could the plastic be letting impurities, or any harmful materials, into the water?

putting boiling hot water in a plastic bottle, would melt the bottle .You should let the water cool before putting it in a plastic bottle.
Can you get money from recycling plastic or does that only work with aluminum in Idaho?
Does the plastic have to be a bottle or just any plastic. How about glass and paper?
Question answered by Mike1942f
Every item made of plastic in recent times has a number inside triangle molded into it. The number identifies the kind of plastic. Not all kinds can be recycled. You will have to ask whether the places that take stuff for recycling will pay anything. Generally they don't for anything but aluminum, but it varies by local and from year to year.
Would plastic wood be good to use on models?
I've already found out what plastic wood is on here. Now, I need to know if it would be good on model cars, or if anybody here has used it on model cars.

Plastic wood might be useable - what are you doing?
If your're filling in seams and gaps it may be ok in very small amounts - but you need to check on a piece of the 'parts tree' to see if it'll melt your kit plastic (some kits are very soft plastic). Try wetting the surface slightly (like wetting the tip of your finger), then smoothing it out before it hardens. If it has a different density than the plastic you may not be able to sand it smooth after it hardens without damaging the kit.
If you are sculpting a piece to add to the kit, it might be easier to sculpt it on a piece of foil or cellophane wrap, then superglue it to the kit after it CURES (curing is different than drying - drying may take an hour or two, curing can take a day or two especially if it's thick). If you glue it on (or paint it) before it cures, it will be ruined.
Your best bet is to go toa craft store like Michaels or AC Moore and buy some plastic model kit putty (Squadron Shop putty is the best and some regular stores carry it as well as most hobby shops, but there are others you can buy as well).
Be sure to tell them you need putty that can be used on plastic.
How is plastic made strong for planes, etc?
I have heard that airplane/aircraft wings are often made out of plastic.
Not the plastic that we see everyday, but strengthened plastic.
I have to do a PowerPoint on this subject. And I was wondering if anybody knows how researchers and scientists have been able to strengthen plastic.
If I can have information/links I would greatly appreciate it.
Anything that has to do with strengthening plastic and how its done would be great.

Most aircraft wings are made out of metal, however in modern aircraft the use of carbon fibre reinforced plastics (CFRPs) is quite common. For example, 22% of the weight of the Airbus A380 is made up by CFRPs.
As the following article states, the new Airbus A400M military transport aircraft will have an all-CFRP wingbox. (The wingbox is the primary load-bearing part of the wing).
http://www.compositesworld.com/hpc/issues/2005/September/977
It also says that CFRPs will make up over 50 % of the structural weight of the the still-to-be-built Airbus A350 and Boeing 787. The wing leading edge and stabilizers will be the only visible metal parts left!
It's clear that plastics are the future in aircraft construction. For more information about CFRPs, check out Wikipedia:

How to really clean a plastic bottle but not have soap smell or residue left behind?
I have a plastic bottle that I use for various liquids and it needs to be cleaned desperately, but I do not want to use the regular soap and water method because last time, it didn't really clean it that well and it also left behind some soap smell as well as a bit of soap residue along the sides. (Yes, I thoroughly rinsed it). I've tried rubbing alcohol, but it didn't clean it that well. I'm thinking of trying bleach next, but does anyone have any suggestions on a solution or chemical that I can use that does a REALLY, REALLY good job of cleaning something? Thanks in advance.

Question answered by Gabriel
You can use lukewarm remember you can not use hot water because the bottle is plastic and can affect or melt. In the market exist a tablets for clean. Some there are some cleaning tablets with odors and other, you can ask in the farmer or shopping center of janitorial.
This we can use with cold water or hot water is very easy, you put the water in the plastic, them wait a few minutes, this depend of the label instruction is a paper paste in the bottle of pastille.
You can use some janitorial supply for dry the bottle, but after remove the liquid.
What can we do to reduce the plastic polluting our environment?
Plastic is made from fossil fuel, the same as our gasoline. So everytime we buy something plastic we are using more fossil fuel. We have plastic bottles, plastic bags, plastic everywhere that may take thousands of years to dissolve. What can we do as consumers to reduce the amount of plastic that ends up in our landfills besides the most common answer of recycle?
I'm not looking for simple answers here. I'm looking for an informed discussion.
It's too easy to say, recycle, don't buy plastic, etc. Plastic is everywhere on almost all things we use. Our cars, in our houses, furniture, anything you buy has some plastic in it.
What are some different ideas for reducing the amount of plastic disposed in our environment.

Thank you for posting this question. I appreciate your concerns on this.
The next threat to this plant is Global Warming and pollution. In most of the countries plastic is burnt out which produces carbon dioxide and other harmful gases. This carbon dioxide is a real culprit which causes the Global Warming. I see people are going away from natural lifestyle and becoming more and more synthetic, by mind and by possession also. We should kick start the awareness in the community and on global level to discard the usage of plastic unless and until it is absolutely necessary and there is no substitution for that. Using plastic bags as a carry bag is a foolish idea as there is a simple substitution for that. And this contributes to major part of pollution whether it caused by burning or dumping. People should be made aware of ecological balance, environment care. And most importantly, these things should be taught in schools as compulsory learning. There should be compulsory essays on these topics in schools. Not forgetting, our children are the next generation which can save this planet, so it is utmost necessary to educate them on this and imbibe the thoughts of care and love towards nature and environment.
Is it better to put a plastic vapor barrier up over the concrete foundation walls when finishing a basement?
Some contractors have said that the plastic vapor barrier will keep moisture from getting to the 2x4's/drywall but others have said that it will actually create moisture since plastic cannot breathe but concrete does. So what's best: plastic, or no plastic? Thanks and God Bless!

Question answered by Brendan P
I never heard of using plastic on the walls. Alot of contractors use plastic over the stones before concrete is poured to prevent moisture from coming up through the floor. Actually if they do not use the plastic often the floor can not be painted as the hydrostatic pressure will pop the paint. For your walls I would just coat the walls with DRYLOCK or Sherwin Williams has a product called H and C Basement and Masonry Waterproofer. if you go to a Sherwin Williams store they are more of an expert then your local LOWES OR HOME DEPOT
What causes plastic eyeglass lenses to turn yellow?
I've had a pair for over ten years. They are plastic, hi-index. A few years ago they started to turn yellow and are now noticeably yellow. Is this caused by UV exposure? Can it be prevented?
I'm having new plastic lenses made, by Essilor, I think. Are the newer lenses less, with their newer materials and technology, less prone to yellowing? Thanks!
McRib
Question answered by U V
Yeah... this is just wear and tear of the plastic material.. constantly exposed to sun-light (and UV). Most hi-index lenses will have a multicoat - which includes a UV inhibitor, and this can go yellow over time.
As for your new lenses... if they're SINGLE VISION lenses... most companies are quite equivalent. Also, how high is your hi-index? 1.60, 1.67, 1.71, or 1.74?
1.60 = Hoya (japanese) Eyas is best.
Higher than that... they're all the same..
Lens designs now are much improved. If you have lots of $$, then go for the 'FREE-FORM' lenses... They reduce high order aberrations.. as well as reduce peripheral distortion and 'swim' effects.

How to get rid of plastic smell from new shower curtain liner?
A week ago I got a new plastic shower curtain liner and hung it up. It gave off a strong plastic smell (I don't know how else to describe it), but that wasn't unexpected for a new plastic curtain. But, it is still giving off that strong plastic odor seven days later.
What can I do to get rid of the plastic odor?
Hooray for Everything
Question answered by Simon M
You can't unfortunately.
These types of plastic shower curtains are made from vinyl (PVC, essentially) which in its pure state is a very stiff, rigid plastic. In order to make the material softer, so that it moves like a normal curtain, the vinyl incorporates a "plasticiser" which is a liquid that sits between the plastic molecules thereby creating a looser, softer stucture.
Vinyl itself has no odour, what you can smell is the plasticiser, and since it will always be present in the vinyl there is nothing much you can do about it. Generally speaking, lower cost vinyls tend to incorporate lower priced (and more unpleasant smelling) plasticisers.
