what solution can light a light bulb?pls pls pls?

If u meant what solution would conduct electricity then any salt solution would do  the trick. If you meant what solution would produce electricity to light a bulb then you need to prepare a dilute solution of sulphuric acid ( be careful! wear gloves! Wear goggles! If you are a kid, do it under supervision of an adult..that means your parents or teacher :-) ) In the acid solution suspend two plates of dis-similar metals ( say zinc and copper) and connect the plates to the bulb( a flash light bulb, 1.5 V) using copper wires..and see it glow.\n\nThere are other ways and more elegant styles..however this is the simplest.

check out hydroponics, soilless growth, with sodium halide lamps. Amazing growth rate but expensive for electricity. you can find the right kit on ebay. happy growing, man:)

Here's an idea. Make one that will shock people(low voltage) when they ring your bell. ;-)

I would probably use Light Emiting Diodes connected to a low voltage dc source using very small gauge twin-lead wire.

I suppose it should not be a problem.  Only the high voltage should let the bulb fail.  check the voltage rating of the bulb.  The input voltage should not be higher than the voltage indicated in the bulb.

1. A battery lighting up a filament bulb.\n\n2. Use LM317 IC to build a constant current source.\n(http://www.uoguelph.ca/~antoon/gadgets/sccs.htm)\n\n3. Battery Charger

Ok, this is how you do it.  You need to have the following items: A coil of copper wire, a barrel shaped magnet, a tube, and a bulb.  Take the tube, and this could even be a paper towel cardboard center, and wrap coils of wire around the outside of the tube as many times as you can.  This should cover the outside of the tube.  Now, take the two ends of the wire and connect them to the + and - of the bulb that you will be using.  You must then place the magnet (a barrel magnet is best, but any will do.  The stronger the better) inside the tube, and cover both ends of the tube.  Now, as long as you are shaking the tube lengthwise, and the magnet slides up and down inside the tube, the bulb will shine.  To make a more practical flashlight, you could do one of two things.  Either have an electrical storage device that will hold the charge so you don't have to keep shaking it, or you could rig something up that will keep the magnet moving inside.  Either or both will work.

There is indeed a machine, called a light meter, that you can use. You an also use a device called a Secchi disk which is much more low tech.

The old potato powered lightbulb.

1) write a book like "lords of the rings" and make big buck and share with us here who have answer your question.\n\n2)invent something, just imagine what would it be like if edison didnt invent the light bulb. Imagine somebody at that time tells you the he will make light without fire or talk to a friends miles and mild away at that time.\n\nanyways...get a rest and do something like fishing, hiking, or better yet try to answer question on yahoo answer.\n\nhappy huntin'

It's impossible to say considering you give no indication of your lighting needs.\n\nThey do make fourescent bulbs which fit into regular incandescent sockets.  The flourescent bulbs use a lot less energy.

there should be a botton (like a light switch) that you can push to see if your light shuts off! but your prolly jus asking this ? to be a smart ass!  \n\n*sometimes when im board i like to put my little brother in there to make sure it shut off!

Check out this company - that are awesome -\n\nwww.lightimpressionsdirect.com

I'd probably choose luminescent due to the cheapness and effectivity of the lightbulb; I personally don't like the light a incandescent light bulb gives off.

It sounds like you are creating a basic electrical circuit. with the batteries, wires, bulbs and paper clip you can make either a series or parallel circuit. The light bulbs will light up when you have a complete single loop for series. When you measure the current it should be the same anywhere on the circuit. In a parallel circuit you are splitting the circuits into three or more branches, with one bulb on each side. When measured each branch should be using half the current. You shouldn't have any problem finding a site online that shows this experiment. use keywords, including science experiments for kids. I found the experiment in Reader's Digest,"How Science Works"

Turn off the lights and go home, \n;-)

It takes energy to push that current through your lights and appliances, and that's what your paying for. One way to see it is to consider that what comes out the downstream prong is at 0 volts and therefore of no use to anyone. Or, you could just wire all your lamps in series and see how that works!
