Rainworks
In October, about a dozen Rotarians from the Rotary Club of Eau Claire Morning, Wisconsin, along with some of their family members, used a product called Invisible Spray to stencil temporary, water-activated artwork on sidewalks throughout the city.
Rainworks, manufacturer of the hydrophobic, nontoxic liquid spray, donated the product, which allows users to create designs that only appear when the sidewalks get wet. At a cost of about $130, 16 ounces can cover up to 110 square feet. “We thought in the difficult times of the pandemic, we could bring smiles to our community” and inspire other organizations to do the same, says Sarah Stackhouse, a co-president of the club.
 A “thank you” below an image of a fire-fighter’s hat was traced outside a fire station, while a drawing at the entrance to a theatre featured musical notes and suggested “singing in the rain.”
