Conductors are materials that will allow electricity to flow through them. Materials that contain 1, 2, or 3 valence electrons are good conductors. Some examples of good conductors are gold, silver, aluminum, and copper. Insulators are materials, or combinations of materials, with a high number of valence electrons (5, 6, 7, and 8). Examples of good insulators are porcelain, glass, air, and rubber.
If you are talking about the balsa wood then you just need to just the wood into necessary parts of the suspension bridge.Download pictures of suspension bridge and then carve out the lower part with roads and put holes on the sides of the flat wood for lower part.Then make the towers to which the cables are attached.You can either design yours or see the picture and carve or cut them out.Let the shape be simple as you want it to be easily and quickly done.Drill holes in the tower at the top on the sides so to attach the cables.Make sure that the pillars or towers are much larger in length as you will see it in the picture you shall download(** MAKE ONLY ONE PILLAR JUST TO SYMBOLIZE).So let the towers be like that.Get the cables either of plastic strings or some soft metal strings and let them pass through holes and tie a knot at the ends to fix them there.Making the bridge out of the balsa wood shall be a not more than 8 hours of consistent working.So Just make sure what you are making and draw out what you are going to make how it is going to look. Using a different material might reduce time like thermocol sheets but as they are fragile so it can be difficult to do the job with them.

"How to Make Red Fort With Thermocol"
The chemical name for thermocol is expanded polystyrene (EPS), which is a synthetic polymer made from the monomer styrene.
Yes.
how to make school using thermocol
Yes, thermocol balls are made of expanded polystyrene foam, which is less dense than water. This is why thermocol balls will float on water.
no
its plastic
Because the heat supplied to thermocol is absorbed by the water inside thermocol and this continues till the temperature reach the boiling point of water. Once the temperature reaches to boiling point of water then the temperature of water inside the thermocol is same as the temperature on the outer side of thermocol facing the heat and then only the thermocol glass will start burning.
