步驟 1: Prepare and sketch

Wash and dry your rock. A triangular or cone-shaped rock works best for a volcano. Use a pencil to divide the rock into sections: the mountain base (bottom two-thirds) and the eruption area (top third).

步驟 2: Paint the mountain

Paint the lower portion of the rock with brown paint. Add darker brown or gray streaks along the sides to create depth and rocky texture. Blend the colors slightly where they meet for a natural look.

步驟 3: Create the lava flow

Starting from the top of the rock, paint streams of red and orange flowing down the sides. Make the lava thicker at the top and thinner as it flows down. Add yellow highlights in the center of the lava streams for a glowing effect.

步驟 4: Paint the eruption

At the very top, paint a bright explosion of yellow and orange bursting upward. Add small red and orange dots flying outward from the crater to represent volcanic debris. Use black to outline the crater opening.

步驟 5: Add details and seal

Add smoke wisps with light gray paint above the eruption. Paint a few small rocks or boulders at the base using dark gray. Once fully dry, apply clear sealant to preserve your erupting volcano.

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。
