Step-by-Step Instructions
-
Prepare the rock
Wash and dry your rock. An oval or round rock works well as a watermelon slice. Cover your workspace with newspaper.
-
Paint the green rind
Paint the outer edge of the rock with dark green paint to create the rind - about 1–2 cm wide all around. Let dry.
-
Paint the white inner rind
Inside the green rind, add a thin white stripe to separate the rind from the red flesh.
-
Fill with red flesh
Fill the center area with bright red paint. Apply two coats for vivid color. Let each coat dry fully.
-
Add seeds and seal
Using black paint and a toothpick, scatter 5–8 oval watermelon seed shapes across the red flesh. Seal with clear sealant when dry.

Add RoxGeo Code
On the bottom or back of your rock, write ROXGEO.COM followed by a slash and your rock’s unique code (e.g. ROXGEO.COM/ABC123). This lets the finder go directly to your rock’s profile page and log their discovery. If the rock is too small for the full address, write #ROX followed by the code without spaces (e.g. #ROXABC123) — it’s short, easy to search on Google, and leads straight to your rock’s journey page. Use a fine-tip permanent marker or acrylic paint pen, and seal it with clear varnish so the code stays readable through rain, sun, and adventure.
Helpful Tips
- A half-circle shaped rock looks exactly like a watermelon slice.
- Add light green zigzag stripes on the dark green rind for realism.
- Keep seeds oval and pointed - watermelon seeds have a distinct teardrop shape.
- A gloss sealant makes the red flesh look juicy and fresh.
- These bright summer rocks are wonderful for hiding at the park.
