How To Make a Sun Jar

Light up someone's life by capturing sunshine in a jar for them.


  • TIP: Double-check that the light-sensing diode is visible through the lid: It's the component that tells your sun jar to light up at night.
  • Step 1: Set the jar in the sunlight. When the sun's rays hit the solar panel, they'll charge the battery. Once the sun goes down, the light inside the jar will turn on automatically, using the solar energy stored in the battery.
  • Step 2: Bask in the sunshine – even at night!
  • FACT: In one hour, the sun provides enough energy to meet the entire world's needs for one year.
  • Step 3: Glue the LED circuit board in the center of the solar panel, placing the light-sensing diode so that it is visible from the top of the jar's glass lid. Carefully close the lid.
  • Step 4: Glue the battery holder and battery to the solar panel, leaving room in the center for the circuit board.
  • Step 5: Check the type of screws used on a solar garden light, which you can find at garden stores. Use the appropriate screwdriver to remove the solar circuitry from the light. The circuitry will consist of a solar panel, a light-emitting diode, or LED, a light-sensing diode, and a rechargeable battery holder with battery.
  • Step 6: If the components are attached to each other or to a plastic casing, pry them apart, but keep their wires connected.
  • TIP: You may need a utility knife to cut the battery holder out of its plastic cover.
  • Step 7: Using an adhesive that can attach plastic to glass, glue the four corners of the side of the solar panel with the lines running across it to the underside of the lid.
  • Step 8: Frost the inside of the jar with a frosting spray, let it dry, and then spray another coat. Don't frost the lid.
