Create a marble effect on a plastic pail with leftover nail polish. Brush a coat of primer onto the exterior and the inner rim of your clean pail. Once dry, apply two more coats of paint, letting the pail dry completely between coats. Fill a container with enough room-temperature water to fully immerse the pail. Drizzle about ¼ of the bottle of nail polish over the water to create a film on the surface. Immediately swirl the polish using a skewer before it gets too sticky, then dip the pail into the water container at an angle and rotate it, allowing the polish to adhere. Pull the pail out of the container, let the water drip off and place upside down on a covered work surface to dry. Flip it over and fill with a leafy or flowering houseplant, making it even better for our environment!
