You may be able to design a device with little or no electrical knowledge or experience that is relatively safe for perhaps 99% of the population, depending on dumb luck and how you apply it, only to discover you are the unfortunate 1%.  Your entire idea is well ... shocking!

Well, this may not be an animation, but it is a pretty darn good online text covering introductory electrical engineering concepts.\n\nhttp://www.ibiblio.org/obp/electricCircuits/

Sounds like you already have some fantastic ideas!  I personally like the soda can and chocolate bar method.  I have to admit, I'd never heard of it until you mentioned it.  Now, I look forward to trying it.\n\nDon't forget flint.  That's an effective and popular method.\nYou don't necessarily need the 9-Volt battery with steel wool, I've seen it done with flashlight batteries.\nYou can still do the condom and water, just use a clear balloon (if you can find one).\n\nI'd stay away from chemicals for that age group.\n\nHere are some links for you to take a look at...\n\nhttp://www.onagocag.com/fire.html\nhttp://members.cox.net/bsatroop218/skills/nomatch/nomatch.html\nhttp://www.christianhomekeeper.com/fire.html\nhttp://www.fieldandstream.com/fieldstream/outdoorskills/article/0,13199,1149562,00.html\nhttp://www.alpharubicon.com/primitive/firewithout.htm\nhttp://www.bizarrelabs.com/firebow.htm

You are making a small battery and experiencing "galvanic shock" due to a reaction between your saliva, your fillings and the aluminum foil.\n\nSearch "electromotive series" for thousands of references.

If you can find and cut the power supply do it. Otherwise try to pull the person by grading him from the clothes DO NOT touch his skin with your bare hands 'cause you'll be electrocuted too.

Ok. Try This.....\n\nStart with a clear glass or plastic jar, some stripped wire, a strip of aluminum foil, and a larger piece of aluminum foil. \n \nBend the wire over the top of the jar so that it goes over the middle and is wrapped around the opening of the jar. Now fold the aluminum foil strip over and drop it over the wire, so that it hangs down into the jar.  \n\nNext take the larger piece of aluminum foil: make it roughly circular by cutting or folding the corners underneath, and press it over the top of the jar. Next wrap electrical tape (or any tape) over the edges of the aluminum foil holding it to the jar. Finally smooth out any bumps in the foil. \n \nYour electroscope should look something like this. \n \nComb your hair a few times and hold the comb close to the top of the electroscope. The ends of the aluminum foil should push away from each other because of electric charge. \n \nYou can discharge the scope with your hand while holding the comb close to the top of the scope. \n \nMove your hand away. \n \nMove the comb away. \n \nA charge has been induced into the electroscope. When you were discharging the scope charge remained close to the comb and when you moved the comb away that charge was released to spread through the rest of the metal parts including the aluminum strip. \n\nHope this helps.

May b u cud try something from a post office box. Its simple as its based on wheat stone bridge.\n\nOr may be u cud study effect of frequency on reactance of inductor/capacitor. \n\nThese r easy and all viva is from theory only. No need to study extra...\n\ngud luck for ur boards.\n\n\nthere is nothing like 'good level'. u cud pick up any topic, even the simplest 1 n make a gr8 project out of it. some more suggestions - time period of physical pendulum, obtaining points where b=0 for various magnets etc. dont u hav enough lab manuals, friends to give u details. ask ur teachers they will help u.\n\n\naur waise bhi yaar, just chill, if u dont make ur proj ur school will surely make 1 for u. after all its reputation is at stake

Someone has used a gasifier and captive-piston engine to make a one-moving part alternating-current generator. The piston is magnetized and the coils are in the body of the cylinder. The trapped air in the cylinder at each end of the piston acts as an air shock to eliminate rebound and impact damage. No sensors needed. No make and break circuit. The voltage drops to zero at the end-points of travel of the piston. Search on this and you can probably find the same one I saw. I think this is where they got the idea for those new shake-up LED flashlights.

I once read about a device with which reconditioning may be achieved 90% of the time on some types of batteries by applying a very brief, high voltage pulse (kinda like a camera's flash system) across the terminals of individual rechargeable cells.  I tried an improvised version of it with NiCD and sealed lead batteries, and it seemed to work most of the time.  I couldn't find plans for the device when I searched just now, though, so I can't really tell you more than that.  Unless you're knowledgeable in the field of electronics, I suggest you just get another battery because the method of recycling I just described may be dangerous.

use a potato and two different metals as electrodes. The link will help you, do your own homework, or web searching atleast! it was the second link in google for g** sake!

take a common butter knife and a paper clip.  Unfold the paper clip and re shape it into an angled "U".  Drape it over the knife edge, hold your arm strait and Try to keep the wire still.\nYou can't.  The harder you try, the more your muscles tremble.  A Robot does not have that problem.  A surgeon can use a robot to eliminate the problem so that she/he can do very fine surgery.

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel

Yes the electricity sparks can cause an explosion. I read about that a long time ago.

It's possible.  For a given source of electricity, there's always a trade-off between voltage (the potential or "pressure" of an electric current) and amperes (the "quantity" of electricity).  A tesla coil, for example, can take 110-volt house current and ramp it up to millions of volts; but the amperes are very low, so one usually doesn't feel more than a tickle.  The danger with a Tesla coil is that if it isn't wired correctly, some of those volts get traded back down for amps; and then you can have a nasty shock.  The human body is largely made up of water, so it doesn't take many volts to overcome the body's electrical resistance.  Even 6 volts is enough -- witness a car battery.  It's the amps that'll get you.\n\nAn analogy would be the difference between a cosmic ray passing through you at 186,000 miles per second, versus a bus hitting you at a mere 30 miles an hour.  You'll definitely feel the bus more.\n\nSo even a nine-volt battery (I assume you mean a "transistor" battery rather than a car battery) can deliver enough amps to hurt.  Because a battery delivers its charge at a slow rate (low amps), you have to use a capacitor to "gather up" enough electricity to deliver a charge at enough amps to make it hurt.  Theoretically, you could drain all of the charge from a battery into a capacitor, then let it all go in one burst; which I imagine would be enough to really hurt, if not actually kill.*\n\nI don't have a 9-volt handy to check the ratings, so I couldn't say what the maximum would be.  Maybe someone else here knows that part of the answer.\n\n* Just as a person can drown in 1 inch of water, so is it possible for someone to be killed by even a small current of electricity.  If the charge was delivered from one hand to the other, for instance, which would take the current across the heart, even a small shock could be fatal.  A pacemaker, for instance, delivers electric shocks to the heart which are measured in mere millivolts; but if that shock is delivered improperly it can cause heart failure.\n\nOh, and P.S., that's why you don't play around with the insides of a television, even if it's unplugged.  There are several capacitors in there which continue to hold a charge for a very long time, and have more than enough amps to kill you.  This has been a public service message.

Nothing more than the standard high-voltage hazard boxed set. You know, fatal static discharges, being skewered by a lightning bolt, that sort of thing. Also they were designed by one of the strangest sci guys ever to show up on this planet- you can't help feeling like there's something wierd about them.

Take precautions against static electricity, especially when you open the box or handle the chip.  Mild static damage can ruin miniature electronics like chips easily.  If you felt the shock, it was probably enough to ruin it right away, more mild damage should show up within six months.\n\nYou've probably learned the static rules, then forgotten bits.  I know I have.  Here's a refresher. http://www.webopedia.com/DidYouKnow/Computer_Science/2002/static.asp

e-mail me: intel_knight-at-yahoo-dot-com\n\nAnd I have no clue how to build that EMP thing, or if it is even possible. I just thought it would be a cool thing to have.
