## Introduction: Salt Water Energy

guys are you want to make energy

Fine!

what you need is ................SALT! ohh not the movieee

the white powder you use in your kitchen

yes the salt!

my last year science project

now What you need are

1. salt

2.water

3.wire

4.led

5.multimeter

6.plastic cup

7.copper sheet

8 aluminum foil

ummmmmm....ahhh!

double-sided tape

## Step 1: Step-1:making Saltwater

first take two glasses

pour water to 3/4 height of glass

mix 3-4 spoons of salt

mix it !

ok now

stick this glasses to the board (optional)

circuit is given above !

## Step 2: Step-2: Peparing Your Circuit

now,

take a piece of copper foil

connect it to the wire (red)

take a piece of aluminum foil

connect it to the wire (black)

now connect these as shown in the image to multimeter

and also to the L.E.D

now the light glows !

## Step 3: Step-3:understanding the Circuit

now 1 glass of water = 0.5 volt

and 2 glass of water =1 volt

you may use as many glasses as you want

now enjoy !!!!!!!!!!!!!!!!!!!!

This is a really cool project! Do you have any more photos of how you built it? Thanks for sharing!

congratulations you've built a wet cell battery using the galvanic potentials of your two metal electrodes and salt water as your electrolyte
