逐步指導

1

步驟 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

步驟 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

步驟 3: Paint the white inner rind

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

4

步驟 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

步驟 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.

步驟 6: 添加 RoxGeo 代碼

在你的石頭底部或背面寫上 ROXGEO.COM，接著加上斜線和你石頭的唯一代碼（例如 ROXGEO.COM/ABC123）。這樣尋找者就能直接訪問你石頭的個人資料頁面並記錄他們的發現。如果石頭太小無法寫下完整地址，可以寫 #ROX，接著是沒有空格的代碼（例如 #ROXABC123）——這樣簡短，容易在 Google 上搜尋，並直接引導到你石頭的旅程頁面。使用細尖的永久性標記筆或壓克力畫筆，並用透明清漆封住，這樣代碼在雨水、陽光和冒險中都能保持可讀。

有用的提示

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.
對於底部的 RoxGeo 代碼，使用防水永久性標記筆（如 Sharpie）或壓克力畫筆。在代碼上塗抹 2-3 層透明密封劑——這樣可以在雨水、陽光和處理中保持可讀數月。
在你的石頭上寫上 #ROXCODE（例如 #ROXABC123）可以讓人通過 Google 搜尋輕鬆找到。我們會主動優化這個標籤，因此任何搜尋它的人都能快速找到你石頭的個人資料頁面。
完整地址 ROXGEO.COM/CODE 會直接帶尋找者到你石頭的卡片，讓他們可以查看完整的旅行歷史、之前的尋找者和每個停留點的照片。
