I have to find out what items can be used as conductors for bulbs. I will have to find out which items allow it to go through and how effectively will it go through? Why do some make it brighter? How come this one doesn’t light up?
I am testing items like nails,rubber bands,foil,copper,etc.
Please help me decide what types of items work the best

MORE DETAILS BELOW:
I am going to set my circuit board which I will use to test my materials. I am going to need 3 pieces of wire with an alligator clip at each end. Then to test each object, I am going to attach one clip of the black wire to the (-) battery terminal by clipping the alligator securely to the terminal. I am going to this again but with the red wire to the (+) terminal. For another wire I am going to use the other end of my black wire to attach it to the light bulb lead. And with my yellow wire I am also going to attach that to another bulb. I will connect my materials between the free ends of the red wire and the yellow wire. I will make a data table for the results, including a place to write the type of material, source of material, and the brightness of the bulb. Next I will place the first material into the circuit by clipping one end to the free red clip and the other end to the free yellow clip. I will repeat this process several times with each material to see

which one make the bulb the brightest!

Silver is the best
Material Resistivity (Ωm)
Silver-------- 1.47×10−8
Copper------1.72×10−8
Gold----------2.44×10−8
Aluminium- 2.82×10−8
Tungsten----- 5.6×10−8
Brass--------- 0.8×10−7
Iron------------ 1.0×10−7
Platinum----- 1.1×10−7

Best Conductive Materials

I assume you mean electrical conductors to light up a light bulb.
The best conductors are gold, silver, copper, and aluminum - in that order, though it does depend on whether you're comparing on a volume, weight, or molar basis.
Generally speaking, any metal will be a good conductor for your experiment and any non-metal will be an insulator. There are some exceptions though - try running the electricity through a pencil lead, for example. It's carbon and non-metallic, but it will conduct some electricity (not well though).
You could also experiment with water. Water by itself isn't a good conductor, but if you dissolve some salt in it it will begin conducting fairly well.
Hope that helps.

Silver & Gold are the best conductors.
But they are rare and expensive. So you might want to use copper or Aluminum- the next best conductors.
It all depends on the purpose of you circuit.

Hi ankush_wah, why can't we mention mica as that one which conducts heat somehow but an insulator for electric current. We often see mica coverage over the heating element in case of iron box. Hope I am correct to some extent.

All metals are conductors
best are silver, copper, aluminium

copper, zinc , aluminum foil is great
water is an excellent conductor IE: electrocution with a hair dryer in the bathtub.
plastic absolutely not...
string, not a chance,
metals and liquids are the best!
