Creating a working model of an electroscope using copper wire, a plastic bottle, and aluminum foil is a great project to demonstrate static electricity.

Below are the steps and materials required for this project:

Materials Required

  • Plastic Bottle: Empty and clean, with the cap.
  • Copper Wire: Approximately 12-18 inches.
  • Aluminum Foil: For making the leaves and ball.
  • Cardboard or Plastic Sheet: For the base.
  • Scissors: For cutting the aluminum foil.
  • Tape or Glue: For securing components.


  • Wire Cutters: For cutting the copper wire.
  • Needle-Nose Pliers: For bending the wire.

  1. Prepare the Plastic Bottle:
    • Clean and dry the plastic bottle thoroughly.
    • Cut off the bottom of the bottle to allow access to the interior. This opening will also help stabilize the bottle when placed on a flat surface.
  2. Prepare the Copper Wire:
    • Cut a piece of copper wire approximately 12-18 inches long.
    • Using needle-nose pliers, bend one end of the copper wire into a small loop or a tight spiral. This will hold the aluminum ball at the top.
    • Create a straight section of the wire (about 6-8 inches) that will run through the cap and into the bottle.
    • Bend the bottom end of the wire into a small hook or loop to attach the aluminum foil leaves.
  3. Attach the Copper Wire to the Bottle Cap:
    • Drill or punch a small hole in the center of the bottle cap, just large enough for the copper wire to pass through.
    • Insert the straight section of the copper wire through the hole in the cap so that the loop or spiral is above the cap and the hook or loop is inside the bottle.
    • Secure the wire in place by adding a dab of glue around the hole where the wire passes through the cap.
  4. Make the Aluminum Foil Leaves:
    • Cut two small strips of aluminum foil, approximately 1 inch wide and 2 inches long.
    • Fold each strip in half lengthwise to make them sturdier.
    • Punch a small hole near the top of each strip.
  5. Attach the Aluminum Foil Leaves:
    • Hang the aluminum foil leaves on the hook or loop inside the bottle, making sure they are free to move and hang parallel to each other.
  6. Make the Aluminum Foil Ball:
    • Take a small piece of aluminum foil and crumple it into a tight ball, about the size of a marble.
    • Attach this ball to the loop or spiral at the top of the copper wire. This ball will help gather static electricity.
  7. Assemble the Electroscope:
    • Screw the cap with the attached copper wire back onto the bottle.
    • Place the bottle upright on the cardboard or plastic sheet base to stabilize it.
  8. Test the Electroscope:
    • To test the electroscope, generate some static electricity by rubbing a plastic comb or balloon on your hair or a piece of wool.
    • Bring the charged object close to the aluminum ball at the top of the electroscope without touching it.
    • Observe the aluminum foil leaves inside the bottle. If the electroscope is working correctly, the leaves will repel each other and spread apart due to the transferred static charge.

This model demonstrates the principles of electrostatics, showing how electric charges can be detected and measured by the movement of the aluminum foil leaves.
