Aluminum foil does not give power to batteries to light a light bulb. The common batteries that we use in flashlights and portable electrical/electronic devices, like the "D" cells, "C" cells, "AA" and "AAA" cells, are made with a zinc can. This zinc outer container for the battery has two jobs. It acts as a housing to contain the electrolyte, and reacts with the electrolyte to create voltage. There isn't any aluminum involved. The actual chemical reactions involved in the generation of voltage in the zinc-carbon or zinc-manganese (the "alkaline") cell can by found by Surfing the link to our friends at Wikipedia. They're down with all this. And you can be to.
Yes. Aluminium is a very good conductor of electricity, and works with salt water.
No you can not
it would be better to store them in foil because no light would get in and do bad things to the food
There are three possible characteristics to a materials reflectivity, which are all due to the orientation of its molecules: Transparent - light travels through the material Reflective - light is redirected away from the material Opaque - light is absorbed by the material Foil absorbing light means it is opaque because that is the definition of the term.
Aluminium is used for soil because it is light and impermeable to oxygen and water.
No you dummy .
The light bulb!
Whatever you do don't put aluminum foil around the end of the light bulb as it burns and that is not safe at all.
to make a torch you need batteries (obviously), a switch (you can buy a standard switch or make a pressure switch out of foil and cardboard), a light bulb, wires (3 if you are using any kind of switch) and a housing (something to hold the batteries, wires, light bulb etc. together). I would also recommend using a light bulb holder and wires with alligator clips (if you dont have solder) as these make the construction more sturdy. they may increase bulk but they are worth it especially as it is easy to replace the bulb and there is no solder needed therefore nothing has to be broken to replace anything.
You would need tin foil ,3 volt battery and a bulb.First you wrap the tin foil around the battery and then attach the bulb your switch will be the opposite side where you place the bulb,if you press i will turn on and if you leave it will turn off.I hope that's helpful.

Foil reflects light
No you can not
Aluminum foil will conduct electricity, so it can be used to complete a circuit and light a lamp..
It should reflect the light.
yes put aluminum foil extending from the positive to negative an feel the heat!!
Many things are reflected from natural light, for example: Solar power light, iron, metal, tin foil and planets (all), moon, mirror. But there are much more too.
