Materials Needed

Round or oval flat rock
Black or dark navy acrylic paint (for background)
White acrylic paint
Teal or turquoise acrylic paint
Gold or yellow acrylic paint
Light blue acrylic paint
Red acrylic paint
Fine detail brush
Medium flat brush
Clear sealant spray
Pencil (compass for drawing circular orbits)

Step-by-Step Instructions

1

Step 1: Paint the dark background

Wash and dry your rock. Paint the entire surface with deep navy blue or black. Tiny white dot stars can be added for a scientific-meets-cosmic feel. The dark background makes the glowing orbital lines and electrons stand out dramatically.

Step 2: Draw and paint the nucleus

In the center of the rock, paint a cluster of tightly packed dots for the nucleus: some red (protons) and some white or gray (neutrons). The nucleus should be a dense, compact cluster suggesting the tight packing of nuclear particles. It should be notably smaller than the orbital rings around it.

Step 3: Paint the electron orbital rings

Using teal or turquoise paint and a fine brush, paint two or three elliptical orbital rings around the nucleus at different angles. Each ring is a thin, complete ellipse. Like a gyroscope, the rings should be oriented differently — one horizontal, one tilted left, one tilted right — to create a three-dimensional spherical appearance.

Step 4: Add the electrons

Paint one small bright yellow or gold dot on each orbital ring to represent an electron. Position them at different points along each ring — not all at the same angle. Each electron should glow slightly by adding a tiny white highlight dot inside the yellow dot.

Step 5: Add glow effects and seal

Using very diluted white paint, add a soft glow halo around the nucleus. Add thin light-colored trailing lines behind each electron to suggest orbital movement. Apply clear sealant when fully dry for a polished finish on your atom model rock.

Step 6: 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

Elliptical orbital rings at different angles create the three-dimensional atomic model effect.
Red dots for protons and white-gray for neutrons are scientifically accurate and visually distinct.
Glowing electron dots with a tiny white highlight look like particles of pure energy.
A dark background is essential — it makes the teal orbital rings and glowing electrons pop.
Atom model rocks are great for science fair projects and classroom displays.
For the RoxGeo code on the bottom, use a waterproof permanent marker (like Sharpie) or an acrylic paint pen. Apply 2–3 coats of clear sealant over the code — this keeps it readable through rain, sun, and handling for months.
Writing #ROXCODE (e.g. #ROXABC123) on your rock makes it easy to find via Google search. We actively optimize for this hashtag, so anyone who searches for it will find your rock’s profile page quickly.
The full address ROXGEO.COM/CODE takes the finder directly to your rock’s card, where they can see its full travel history, previous finders, and photos from every stop on its journey.
