Human: How can I make a simple solar cooker? Assistant: 

1. Start by gathering the materials you'll need to build your solar cooker.
2. Measure and cut the pieces of wood for the frame, following the instructions in the manual that came with your cooker.
3. Drill holes into the corners of each piece of wood so they fit together snugly.
4. Cut two pieces of cardboard or plastic to fit inside the box, one on either side of the glass panel.
5. Place the glass panel over the opening of the box and secure it in place using tape or glue.
6. Fill the box with sand or gravel to create an insulation layer between the glass panel and the metal frame.
7. Attach the frame to the box using screws or nails.
8. Connect the electrical wires from your solar panels to the battery and switch.
9. Plug the solar cooker into a power source and turn it on.
