Q:Desert Punk. I need some ideas for making a helmet and face shield for a costume?: Leave your hair down and kind it so it appears fairly shaggy like. Wear ripped thin denims and a biig band tee blouse tied up within the again Wear black eyeliner fairly feel and winged out at the most sensible with tons of masscara and pink lipstick

Q:Why does it take so long to extinguish forest fires?: You failed the drug screen and were terminated. There is no malice on the company's part. The fact that it came out diluted the first time, states that you were trying to get it out of your system. The retest was to confirm it since that does not get out of your system for up up 2 months. The check was mailed on Friday you should received no later than Wed.

Q:What is the size of the PVC pipe joint?: In practical applications, stabilizers must be added to improve the stability of the heat and light. PVC is very hard and can only be dissolved in a few solvents such as cyclohexanone, two dichloroethane and tetrahydrofuran. It is stable for organic and inorganic acids, alkalis and salts, and the chemical stability decreases with the increase of the use temperature.

Q:Why don't fire fighters use that white foamy stuff that you get in fire extinguishers to fight everyday fires, instead of water?Basically I was watching the news today and there was some cottage fire's some where in England and it just got me thinking. Is the white foamy stuff in fire extinguishers only good for small fires?That makes no sense though. And also if water is better for the bigger fire's then why aren't fire extinguishers filled with water.As soon as this popped in to my head I knew I wouldn't be able to stop thinking about it.So to recap my main question is;Why is water used instead of the stuff in fire extinguishers to fight fires?Any help would be great. :): When these units are professionally installed, especially on a wood floor, they are always connected to a floor drain. The pans are designed to contain a certain amount of water related to minor spill but would not, (obviously), take care of a major leak. If I were installing this I would locate the floor drain and then cut the pan at the bottom to match the drain. Depending upon the size of your drain, (usually 3), you should be able to by an adapter to slightly raise and seal the drain to the pan. Don't forget to caulk the fittings

Q:Most people have seen the model of the lung with a balloon. How is this different from the actual lung itself? Also what is the advantage of the actual structure of the lungs?: It depends on the surface on which the lightning strikes, the material surrounding the impact zone (wood, mettal,plaster, etc) allso the earthing of the house.Normaly the electronics which ate plugged in will be destroyed (also dengerous if using wirelless phones on the exact moment), generaly on buildings without lightning rod's a small flame occurs at the impact zone but rapidly extinguishes.

Q:A man handling a chemical gets a phone call and accidentally spills the chemical onto his hands without wearing safety gloves. All I wanna know is if this is related to workplace safety.: All meat killed by anonymous trolls is unsafe to eat.

Q:if a room is burning and there are two exits, a window near u and a far door, and u r getting low on air, and u only have a blanket and 1 litre of water,and the door is about 90 sec far running what would u do????: Look at brass fittings, they make ball valves as small as 1/4

Q:cant really figure it outcan you?: no real way to stop them from stealing them but you're best chance would be to install a paging type alarm system so that it will notify you when the alarm goes off, install motion lights where you're car sits, get a dog any size will do as long as it will bark, go to harbourfreight web site and buy a security camera i think they still have them for $40.00, they are b/w with night vision and sound they hook to you're TVs A/V inputs, but the night vision is kinda weak after 20 feet, talk to you're neighbours see who stays up at night and who's home during the day and set up you're own neighbourhood watch, try to park you're car close to you're bedroom window, because they will use a cordless sawzall to cut out the converter, so welding wont help and trying to make a plate to cover it would only increase you're chances for a fire, most scrape yards pay between 10 and 40 dollars for converters depends on the type, the reason is for the honey combs inside of it, its some type of ceramic material, what its used for i have no ideal, but they want the guts out of them badly. I've heard roomers of the honey combs being used for some type of medical research, again its just a roomer. other than locking it up in a garage i guess you could air bag you're ride and set it on the frame when you're not driving lol would be alot harder to get to it that way . best of luck and i would get a good alarm and camera with sound, and try to park close to you're bedroom, if you do catch them in the act i wouldn't confront them keep you're distance, call the cops which will take a hour for them to show I'm sure and yell what do you think you're doing to my car or something like *^*%^*^*%^ away from my *(^%(^% car you ^*%$*^%lol, from a safe distance,

Q:I have a large collection of LPs, many of which are out of print. I'm not a rare LP collector as such but enjoy the music very much and don't want to lose the music I've amassed. What are some opinions as to the risk(s)/benefits of recording these onto CD-R and giving the bulk of this space hogging vinyl over to the flea market?: Sorry, but we cannot tell you much about what will happen because there is not much information. The suitability of the 11/2 pipe will depend on how much flow you desire and how much pressure is available in the 3 Pipe at the point of connection. Also the 2 hp pump data does not really reflect the flow and pressure capability of the pump. Where (which floor) do you intend to put the pump and where is the 1 1/2 connection ? A 1 1/2 pipe will handle about 40 gpm at a reasonable velocity and with pressure loss of about 3 psi per 100 equivalent feet. Equivalent feet takes into account the additional pressure loss Thur fittings. Approx. small water pump horsepower gpm x psi / 5500. Pump head is commonly expressed in feet (of water column). To get the equivalent water pressure (psi) divide feet by 2.31

Q:Okay, so I'm watching Kick-*** (It won't let me type it), and there are metal detectors outside the school?! What? Is that what all American schools are like? So you can't take knives or anything to school? And, does it work? Are there less slashings and stuff?Oh andis as* a swear word in America? I'm confused? It isn't, like, worth being censored in England?: with my kids i make them go outside take awy the controls and limit the amount of time that they play on it. if they try to get back inside i lock the door. your the parent get it under control he's only 7
