It depends which foil and what you are doing... if you are using BacoFoil non-stick the shiny side needs to touch the food, as this is the side with the non-stickyness on. the rest of the foil, it doesn't really matter - just remember that the shiny side will reflect more heat, so the food will cook quicker!

You should use tin foil with the shiny side facing inwards towards the food and the dull side facing outwards when cooking with fire. This can help reflect heat away from the food and prevent the foil from burning.
Well, honey, aluminum foil is a conductor, not an insulator. So, if you're looking to wrap up your leftovers and also conduct some electricity, aluminum foil is your go-to. Just don't go sticking it in the microwave unless you want a little light show to go with your reheated dinner.
foil?
Heating aluminum foil can cause it to melt or catch fire, so it is not recommended to heat it up.
Foil can be a noun or a verb.Noun:She wrapped the leftover biscuits in aluminum foil.orHe drew his foil and prepared to fence.Verb:They will foil my plans of global domination!
An easy way to identify a place with high radioactivity is to roll up a ball of foil in you're hand and when the foil gets warm (Not hot) you are about 12 meters away from a highly radioactive location.
Only a single component makes up aluminum foil, which is the aluminum element. Hence, aluminum foil is considered as a pure substance.

If an electric current passes through a foil, the foil will heat up due to resistance in the material. The degree of heating will depend on the amount of current flowing through the foil and the resistance of the material. Excessive current through a foil can lead to overheating and potential damage to the foil.
The metal foil is a resistor---it conducts electricity but also resists its flow somewhat. When the sheet is bent one way it stretches the foil slightly, making it longer and thinner. This raises its resistance, since the electricity has further to go and a more constricted path to follow. On the other hand, when the sheet is bent in the other direction it compresses the foil, making it shorter and wider and lowering the resistance. Because the foil strip is so long, even slight strains will cause fairly big changes in the resistance, which will be picked up by the Wheatstone bridge.
