Rainworks Invisible Spray

Rainworks Invisible Spray


Science and art come together with Rainworks Invisible Spray, a substance that repels water, letting the user create positive messages and art on the pavement that reveal themselves when it rains. The formula, which is 100% biodegradable, can last up to four months. You can donate to the Rainworks Kickstarter campaign here.
