Q:What plastic is used in flasks?
The highest melting point plastic I found was Polyether ether ketone (PEEK) with a melting point of 640°F. Glass melts at 2600-2900 °F, so plastic flasks are not a viable alternative to glass. The bunsen burner flame using natural gas has a maximum temperature of 3562°F. I suppose you could argue that if liquid was in the flask, the liquid temperature would cool the base of the plastic flask, so it would might work. But plastic is a good insulator as well, so the plastic might start to melt even with liquid in the flask. And if the water boiled away, the flask would melt for sure, unlike a Pyrex glass flask.
Q:What's the most heat resistant kind of plastic?
The most heat resistant is a bit of a trick question. Plastics can react to heat very differently depending on pressure, and other variables. Now to your question, there are two main families of polymers (plastics) thermosets and thermoplastics. Thermoplastics are what you generally think of as plastic. They can be melted and cured multiple times, and include things like teflon, polyester, PVC and acrylic. The other family is thermosets. Once thermosets are cured, they cannot be melted and re-cured (that doesn't mean they don't melt, just that when they melt, they change irrevocably), generally have greater hardness, and include things like epoxies and melamine. In the past, a thermoset material called Bakelite was used for handles for cooking utensils, and a thermoset material called Duroplast, was used to build the German Trabant automobile.
Q:Elastic and plastic collision?
In an elastic collision the prefix word perfectly being omitted, mechanical energy is conserved. In a plastic collision unlike the above there is some permanent deformation due to the collision. This deformation means that some energy was not conserved (ie lost in terms of the total mechanical energy)
Q:Would termites bore through plastic?
Termites often chew through softer plastics. They play havoc with buried cables and sometimes hole water pipes causing service interruptions and major damage. A window is something else. Mostly they'll chew plastics that are buried or hidden away. Sometimes they'll eat through plastics that are up against wood their partying in at the time but they don't often wander out into the open and start such a major chewing job. My guess is that it is something else. Probably best to get a pest inspector around, there are likely to be other, really subtle, clues that will help tell the story.

Q:Help! Burnt plastic on burner!?
The good news is you didn't have a fire. The bad news is you are going to have a really tough time removing the plastic residue. It depends on the type of plastic, but assuming it is the usual type of softer plastic (such as Tupperware, etc.), these things are heck to remove. You may have to try to heat the burner again, until the plastic just begins to soften, and then use a putty knife to scrape the residue off. Then, when the element is cooler, use a wire brush such as you use on a barbecue grille to scrape the rest off. (DON'T breathe the fumes as the plastic melts ! ) You might also try to write or telephone the company which manufactured the plastic cover, and tell them (don't be embarrassed--you are not the first person to do this. Maybe they can suggest a chemical that can soften the plastic and make it easier to remove. But remember that many chemicals, such as acetone, are very flammible, so you don't want to use it on a hot or warm burner element. That's about the best I can suggest. Good luck.
Q:Would plastic, card or paper make a better sail?
The sail has to take a curved airfoil shape to be effective so card would not be best since it won't bend well. Paper falls apart when wet, not a good choice for a boat. Plastic is the best choice. High tech sails are made with mylar and kevlar, special types of plastic.
Q:Does plastic have to burn to release fumes?
Polymers from some plastics can supposedly leach. This happens e.g. if you microwave something without removing the saran wrap. In general the environmental hazard with plastics and polystyrene is not that they're toxic, but that they will last for thousands of years. It's unfortunately more economical to make them disposable than to recycle. If oil hit $200 a barrel or there were higher pollution fines /landfill fees this would change.
Q:Liquid that will stain plastic...?
Soaking it in hot water with a bit of bleach in it may do it. There is some stuff in the dishwashing detergent aisle at Wal Mart ... it's called plastic booster or something like that. I think you can put it in your dishwasher and it helps get that kind of stuff off. I've personally never spent the money to try it, so I don't know how well it works. I just usually wash the container and surrender myself to the fact that it's just going to be stained!
Q:Paper or plastic?
My wife and I re-use both. The paper seem easier and faster to recycle but the wife says she likes to crochet doormats out of the plastic bags. They all get used one way or another.
