Designed by Jeff Zischke, Solar Soda Lights are made of repurposed 32 oz. plastic soda cups, and a solar module. The ink is removed and designs are cut /drawn experimented with on the cup. The lights need to be charged for 3 hours a day in the direct sun and will last throughout the night for 8 hours. I have drawing/layout plans on the website as well.
