The Pee Battery

Use your urine to make electricity! With the pee battery you can make enough energy to power a small electric motor. It is quite an easy project without the use of dangerous chemicals! All you need is

1. an empty aluminum can (e.g. coke can),
2. a piece of copper,
3. vinegar,
4. crocodile clips
5. and urine

Following tools are handy for this instructable:

• steel wool
• can opener
• electric drill

• Remove the top of the aluminum can. Use a can opener.

• Cans have a coating inside. You need to remove it.
• The easiest way is to scrub it using steel wool.
• By using an electric drill you can get this job done faster.

• First, add urine to the can. The urine will act as electrolyte.
• Second, add vinegar to the can. The vinegar will boost the voltage as it adds more acid to the electrolyte of this battery.
• Third, put a piece of copper in the electrolyte. Connect it with a crocodile clip.
• Finally, connect a second crocodile clip to the can. Make sure it touches the inside of the can.

• The aluminum of the can is the cathode, which is the negative terminal.
• The piece of copper is the anode, which is the positive terminal.
• The urine in the can is the electrolyte.
• Now chemical reactions inside the can create opposite charges on the copper and aluminium can, but the urine prevents the charge from flowing.
• If you connect a motor to both crocodile clips, the charge flows through and powers the electric motor!
