electricity experiment help

[Got nads?]

Does anybody know how to light a light bulb, using simple everyday materials you can use i.e. if you are stranded on an island. Can be anything! You can use water, wind, or something of that sort. The only way I know how to do this is by using a potatoe as battery. Please help!:confused:

if you have a CB you can hold a flourescent bulb up to the antenna when you key the mic and it will make it light up

I remember doing a project like that back in highschool . We had used lemon juice , cause of the acid, and some wire . There's more to it ( but i forget what) and it made the bulb light up . :D
