When I was that age I jumped off a cliff high enough that one of my eardrums burst. I had to have a piece of skin from behind my ear grafted onto it. I think I win.

Lets just say my body hit the ground quite a while before the screwdriver.

Figuring a screwdriver has plenty of insulation to draw tesla coil arcs safely.

I have seen these markers and I was wondering if anybody knew the chemicals used in making them. The paper that goes with the markers is coated in some type of solution that will turn the clear ink in the markers the corrisponding color but each marker turns the paper a different color. Anybody know how they make them?

Make sure it contains lots of high voltage and explosions.

I'm trying to learn japanese.

I did the same thing but I put it in a rod shaped mold for an electrode in electroplating.

30V will NOT spark through the air without preionization. However, Assuming you can supply enough current, if the wires come close enough together to touch the tips will heat up enough to ionize the air. The wires can then be pulled back creating an arc between the wires. This works much better with carbon though.

I disagree. Although ionization CAN happen first it does not always. It completely depends on the conditions. If you have two spherical electrodes the air will ionize the same time the spark forms because the spheres reduce corona keeping the air from becoming ionized. In triggered spark gaps a higher voltage spark will ionize the air allowing a lower voltage discharge across the gap. Also, a spark IS ionized air (plasma).

ET has a linux version. And its FREE.

They have the opposite effect on people with ADD.

What are everybody's views on stimulants (such as Ritalin and Adderall, but not limited to) prescribed for AD/HD? I few topics I'm interested in: Stimulants prescribed for school-age children Teachers pushing stimulants on students Stimulants prescribed for adult ADD

Ill second that, but not that.

I can handle B.O. or potential death, but certainly not both at the same time!

Splitting salt or buying sodium? I was referring to the former.

Melting the salt is the easy part (use a plumbers torch and a brick), the hard part is getting metallic sodium. At those temperatures the sodium will react with the air almost instantly. You would have to spray the reaction with an inert gas which would make direct heating impossible. You would thus have to heat from the underside which would be much more complicated and require more heat to overcome the losses. Electrolysis of NaCl is possible but if you want it to work it wont be cheap. You might as well just buy sodium off ebay.

Informative? On what?

Thats a fictional compound but not element.

Yes, bismuth is rather nice too. It also has a lot of fun qualities such as diamagnetism. Is strontium really that much better than lithium? Lithium is already ahead just for having a better name.

I'm really glad you live in Indiana.

You don't need the negative outputs, just the positive and ground. Also, if you see a wire thats the same color as another then they are the same output. There is only one 5+ output it's just split into multiple wires. You can use one and ignore the rest.

Yea but I still think copper pwns platinum. Osmium looks nice but I dont have any...

My favorite changes from day to day. My current favorite is copper because you can plate it on to everything. I also think its one of the most attractive elements. Bismuth and gallium are also fun. Mercury is not expensive. Its actually pretty cheap and a lot of people would pay you to take it from them.
