The students built a lamp out of pine cones over four weeks. They cut the needles off of 20 pine cones, attached them to a wire triangle frame using silicone glue, and inserted a metal grille inside to prevent shorts. Though the limited time and initial structural issues caused problems, the lamp was completed using inexpensive recycled materials like pine cones, wire, and metal bars. The project taught the students what can be made from recycled goods without pollution through effort and patience.
