A movement has begun in Emmaus and it’s on the rocks.

As a community building and goodwill spreading activity, folks are painting small rocks and hiding them throughout the borough.

Any group or individual may participate, and the rules are few.

Find a rock, paint it and place the rock where someone else may discover it. Painters and finders are encouraged to post pictures of their rock creations or discoveries on the Emmaus Rocks Facebook page.

The Facebook page also reminds participants to avoid placing rocks where someone may trip over them or where they may cause property damage. In addition, rocks are not to be removed from landscaping and players should avoid trespassing. Since children may find them, all rock decor must be PG and sealing the finished products protects the rocks from weather damage.

The purpose of the activity is to spread joy. Therefore, once a rock is placed, it becomes a gift to the person who finds it. Those who discover the painted rocks may take them for a short time, admire and re-hide them immediately or just let them be.

Rocks are being found by children, adults and even a beagle named Bugle who found a rock in Northwood Cemetery.

Paint on Main hosted an event Aug. 20 to provide supplies and inspiration for those interested in painting rocks.

Take a walk around Emmaus. Painted rocks are popping up everywhere. They come in all shapes, sizes, colors and designs. Some are merely decorated while others contain information about their origins. What they have in common is that, when showing or talking about the rocks, those who have found them smile.

Some rocks have inspirational messages such as “you are beautiful” or “be kind.”
