- Citrus Fruits (lemon, lime, orange, grapefruit)

- Copper nail, screw, or wire (2” long)

- Zinc nail or screw or galvanized nail (2” long)

- Holiday light with 2” or 5” cm leads

- Alligator clips or electrical tape (Optional)

1. Gently roll your fruit on a table to soften, careful not to break the skin.

2. Insert the zinc and copper nails into the fruit so they are about 2” apart. You do not want them touching, and avoid puncturing through the end of the fruit.

3. Remove enough insulation from the lead of the light so that you can wrap one lead around the zinc nail, and one lead around the copper nail. If you like, you can use electrical tape or alligator clips to keep the wire from coming apart from the nails.

4. After connecting the second nail, the light will illuminate!
