if your making one for a model airplane, your probaly gonna have to make a pulse jet.

i read a guide last night and it helped alot. But, i have all my messaging accounts on trillian, and want to keep it this way. All i need to understand is (1. what do i need to type in where it says "server alias". I think i need to type in a network name, but i doubt it. (2. im just confused about the server thing. Can i access any network on one server?

Arent you supposed to be able to use an ipod as an external hard drive? If you can do this, why cant you pull songs from it?It seems kinda wierd.

Can you guy/gals help me get on IRC? I have no knowledge of the way it works. I know i need a sever name. I am running trillian for all my instant messaging, so id like to definetly just connect through this. Is there servers that are better than other? Whats a server alias?

i read that book, i think everyone here should read it. Great book. Yes, latentheat, this always happens to me, were i here about something, then i here about it alot. The book goes from his childhood chemistry, to more complex chem, then to radiation and light energy. Has alot of very interesting chemistry history in it also. Thats funny, i told my teacher to read it.

take a cooler and cut one intake vent into the lid, and another hole for a fan. Fill with ice and close. Turn it on and and you got a simple AC. Seeing this thread makes me want to take apart an old minature freezer (maybe, if im careful, not break any of the evaporator joints) and make an ac.

Grinding it with a wood stick would (1. not explode it and (2. would not create a spark. If it did manage to ignite, it would burn very slow. That is, if the stick had been powdered. I read in Uncle Tungsten that if you make a mix of potassium chlorate and sugar, and pour a small amount on the concrete and hit it with a hammer youll get a bang.

like a mobile? A mobile phone? If thats what you mean, then the radiation that Bi emits is completely different from microwave radiation.

i love saying dihydrogen monoxide to people as a joke. I had a small vial at school, so i filled it with water and pretended to trip and spilt it on some kid and i was like "oh crap, i got dihydrogen monoxideon you" and he started freaking out.

go to the auto parts store and ask for battery acid.

Are your anodes/cathodes made of copper? Sometimes during electroysis with salt solution you get a copper complex or something.

So, im wondering, how do insects and plants go about producing these esters?

i thought it was 1983. I used to get my zinc for casting out of pennies,but it is boring and imoure, so i bought a five pound zinc 99% boat anode of ebay for like 10 bucks. I had to melt it into little blob ingots so i can remelt them latter. It took like 20 minutes to melt the thing with a MAPP gas torch!

I have. You can buy 99% NaOH form the hardware store as lye drain cleaner. Eats hairs and other organic "drain cloggers".

well, isopropyl alcohol dries realy fast to.

I already mentioned an attachment thing that they already made. Um, tommlo, why does your ranking just say "registered user"?

budelwegraph, this is obviosly his first post here, so dont give him a hard time. Please give more imformation.

i love those neodymium magnets. Ive been severely pinched by one though. I got mine when i took apart a seagate 2.11 GB hard drive that came out of a packard bell running windows 95. Now i wish i hadnt destroyed it, i could of put it in my dell to store music or other crap. I wonder if this would even be possible becuase its so old. Oh well, not like i need it, i still have like 101GB with four movies on it and a few gigs of music. Its a 144GB hard drive. How about this, a hard disk floppy. Kinda like a zip, but with a hard dist instead. Do you think it is possible to do something like this? It would need a whole new drive though.

Im sure the ULTIMATE sharpie remover is 99% isopropyl alcohol. Instant.

Well, dont they make those things you screw onto bottles that you pump to keep the pressure up so it doesnt gradulaly go flat. I dont imagine this would work though.

I heard you just have to boil acetic acid with your alcohol and distill the product and theres your ester. Btw, what ester is created between Isopropyl alcohol and acetic acid? iospentenyl acetate? Im just guessing by the "iso" prefix.

Funny, crash. About the carbonated thing... iM NOT SURE THATS POSSIBLE WITHOUT MAKING THE DRINK HAZARDOUS TO HIMAN CONCUMPTION. i HATE CAPS lock.

Tonight we had some low clouds and i actualy hit the clouds with my laser. Amazing. I also tok apart a red laser, pretty amazingf succh a small diode can produce so much light.
