The Kindness Rocks Project is sweeping the nation. Here's how it works: Paint a rock with bright colors and a positive message, then hide it somewhere for a friend or stranger to find. If you find a rock, read the message and re-hide it. Spread kindness, encouragement, and happiness one rock at a time with this ready-to-use kit. Includes 10 natural river rocks, water-resistant paint, 2 brushes, more than 30 waterproof transfer designs and 4 metallic gold transfers. Ages 6 and up.
