Back to Light is a creatively scientific series by photographer Caleb Charland that explores the naturally electrifying power of ordinary objects like fruits and loose change. The images in the series features a number of materials, including consumables readily found in one's pantry, generating enough power to light lamps and LED lights. We had previously seen Charland light a lamp with 300 apples, but now the grocery list has expanded to include oranges, lemons, limes, grapefruits, pomelos, and vinegar.
