I have 4 electrical wires that i need to "switch" together via a relay, example: wires 1234 5678 9QWE, wires 1234 normally connect to 5678 but i need to switch them so 1234 breaks from 5678 and goes to 9QWE, obviously i could do it with 4 two-way switches but i only want one that switches them all together. hope someone can make some sense of this. Thanks

Carter seeing a U F O ,do you think there are exterestial beings visiting our planet or maybe a form of terestial being that have always lived among us but we are unable at times to see or comunicate with them Is it possible that these things are God,angels or maybe the devil and his demons ?It appears that many credible witinesses have testified that they have seen these things without any apparent agenda except to expose the truth.What do you think?

http://s180.photobucket.com/albums/x245/vrooom911/

I live in Houston, TX and keep finding these orangish spiders in my bathroom. They don't seem to jump much and aren't very fast. Please let me know what type of spider this is and if possible some helpful websites for spiders as I cannot find a picture of these anywhere. I don't think they are posinous, but it is always nice to be certain. Thank you

I watched the moon walking footage form the Apollo missions and I have a simple question: I don’t understand why the dust or fine sand always falls immediately to ground while the astronauts which are much heavier have to deal with the lesser gravitation. Isn’t this mass related: the heavier the faster one should drop (Newton) and therefore for the dust with less mass and gravitation it should take much longer ? Just curious? Note I haven’t made my mind up what I should believe about the whole thing. This is a scientific question, ok!
