Printing Without a Printer

A group project where we mass-produced a random expression without using a printer or ink. My group juiced enough red cabbage to “paint” more than twenty-five 2’x4’ sheets of paper. We then carved each letter into a cabbage halve. Red cabbage juice is a known pH indicator, so it changes colors when either acidic or basic liquids touch it. Drain cleaner is one of the most basic substances, so it produced this vibrant, yellow color when it reacted with the cabbage juice.
