逐步说明

1

步骤 1: Prepare the rock

Wash and dry your rock. An oval or round rock works well as a watermelon slice. Cover your workspace with newspaper.

2

步骤 2: 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.

3

步骤 3: Paint the white inner rind

Inside the green rind, add a thin white stripe to separate the rind from the red flesh.

4

步骤 4: Fill with red flesh

Fill the center area with bright red paint. Apply two coats for vivid color. Let each coat dry fully.

5

步骤 5: 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.

步骤 6: 添加RoxGeo代码

在岩石的底部或背面写上 ROXGEO.COM，后面跟一个斜杠和你岩石的唯一代码（例如 ROXGEO.COM/ABC123）。这让发现者可以直接访问你岩石的个人资料页面并记录他们的发现。如果岩石太小而无法写下完整地址，可以写 #ROX 后跟没有空格的代码（例如 #ROXABC123）——这样简短，容易在Google上搜索，并直接引导到你岩石的旅程页面。使用细尖永久性马克笔或丙烯颜料笔，并用透明清漆封住，以确保代码在雨水、阳光和冒险中保持可读。

实用小贴士

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.
对于底部的RoxGeo代码，请使用防水的永久性马克笔（如Sharpie）或丙烯画笔。在代码上涂抹2-3层透明密封剂——这可以让它在雨水、阳光和多次处理下保持可读性，持续数月。
在你的岩石上写上#ROXCODE（例如#ROXABC123）可以通过谷歌搜索轻松找到它。我们积极优化这个标签，因此任何搜索它的人都能快速找到你岩石的个人资料页面。
完整地址ROXGEO.COM/CODE将直接带领发现者到你的岩石卡片上，在那里他们可以看到它的完整旅行历史、之前的发现者和每个停靠点的照片。
