A little history on the soda light
I wanted to make the clock run on grass, so I tried it, and it worked, but it was dim and only lasted for about a minute. So i tried other stuff, that worked but it was expensive fruit, and for that price you could by a small battery. Later in the week we had a party with soda and i tried soda, clearly because it is called SODA clock it worked, and it was bright. And because you can get soda for 40 cents (food max) I used soda.

Step 1:

All you need is a/some:
Two glass or plastic bottles
lemon clock kit (or pottato etc.)
Scrap wood
To make it you will need a/some:
Dremel
Hot glue

Step 2:

Cut two lines for the metal in both of the caps for the bottle.

Step 3:

Drill a in the wood two holes. They need to be far enough apart that you can turn the bottles if the vaps went in them. I personaly think mine is to far apart.

Step 4:

Glue one copper and one zinc rod in eeach cap, and glue the caps in the wood.

Step 5:

Wire it. If you want you can cover it in hot glue to keep the wires from coming undone.

The red wire goes to the copper(in mine).
