Scratch art for kids: make your own without a kit

Art technique

Scratch the black away and a rainbow appears

Colour a card with bright crayon, paint black over it and let it dry. Scratch with a toothpick and the black breaks off in a thin line, showing the crayon colours. The wax stops the paint soaking in, so it comes away cleanly.

What you'll make

Your own scratchboard: a black card that turns into starbursts, a night city or a rocket full of rainbow lines wherever you scratch. Shop-bought scratch paper works the same way; this one costs only crayons and paint.

In Extreme Drawing

Crayon (drawing bar): colour a patch in bright stripes. The crayon only catches the raised fibres of the paper, so go over it a few times.
Paint (drawing bar): paint black all over the crayon.
Time → Wait 1 hour. Brush paint sets hard in about an hour. (Black poster paint from the Paint bucket, Toolbox, sets in a few minutes.)
Craft tab → Poke → Toothpick or Skewer (in the full toolbox): drag it across the dry black. The point breaks the paint along a fine line, about half a millimetre wide, down to the crayon, and the crumbs land just beside the line.

Also try: dragging the toothpick through the paint while it is still wet. It ploughs a soft furrow instead of a clean line. Compare a scratch over crayon with one over bare paper: without the wax underneath, the black has soaked into the paper.

For real

Do it for real

You need

Thick white card (thin paper tears)
Wax crayons in bright colours (leave out the black)
Black poster paint or acrylic paint
A few drops of dish soap (washing-up liquid)
A wide brush
Something to scratch with: a wooden toothpick, a bamboo skewer, an opened paper clip or an empty ballpoint pen
Newspaper under your work

Step by step

Colour every bit
Fill the whole card with crayon, pressing hard. Stripes or patches of bright colour work best. Any gap will scratch out white.
Mix the black
Stir a few drops of dish soap into about two tablespoons of black paint. Without it, the paint beads up on the wax.
Paint it black
Brush on an even coat. If colour shows through once it is dry, add a second coat.
Let it dry completely
At least an hour, overnight is better. Paint that is still soft smears instead of scratching.
Scratch your picture
Draw with the point. Press lightly for thin lines; use the side of a skewer for wide patches.
Brush off the crumbs
Tip the black flakes onto the newspaper and fold it up, so they don’t get trodden into the carpet.

Variations to try

Shooting stars

Scratch bursts of lines out from a point. Rainbow crayon under black looks just like a night sky full of shooting stars.

Halloween

Orange, purple and green crayon under black: scratch bats, a moon and spider webs.

Space

A rocket, planets and stars. Scratch dots for far-away stars and the side of the skewer for comet tails.

No-paint version

Colour bright, then cover it with a thick layer of black crayon or oil pastel and scratch through that. Less mess, but it takes strong arms.

In the app vs on paper

On screen

Drying is one tap (Wait 1 hour), and Undo takes back a slip. The scratch is a crisp line, with the crumbs falling beside it. The crayon, the paint and the wait are free; the toothpick and skewer are in the full toolbox.

On real paper

Real drying takes an hour or a night, and the paint needs a little soap to stick to the wax. But the real card has the scrape you can hear, the shiny wax under the black, and a picture you can hang on the fridge.

Why the paint comes off in clean lines

Crayon is wax, and wax doesn’t let paint soak in. So the black paint dries as a thin skin lying on top of the wax, and a sharp point can lift it off.

For grown-ups. Wax is hydrophobic: water-based paint can’t wet or soak into a waxed surface, so it dries as a separate film with little grip on the layer below. The dish soap is a surfactant that lowers the paint’s surface tension so it spreads over the wax instead of beading up. Once dry the film is brittle, and a hard point concentrates force on a tiny area, cracking it along the line and exposing the wax. Artists call scratching through one layer to another sgraffito (Italian for “scratched”).

Try next: what do you predict?

One coat or two?

Which scratches more cleanly: one thin coat of black or two?

Wet or dry?

What happens if you scratch before the paint has dried?

White crayon underneath?

Will it look like plain paper, or shinier?

Oil pastel instead of crayon?

Oil pastels are waxy and oily. Do they work the same?

For teachers

In the classroom

Scratch art fits art lessons on line and contrast, and the science behind it (wax keeps water out) fits KS1 everyday materials and NGSS 2-PS1-1 (describing materials by their properties, such as waterproof). Scratch a few lines on the whiteboard to show the idea, then let the class predict what dish soap changes.

Questions parents ask

How do you make scratch art paper at home?

Cover thick card with bright crayon, paint it with black poster paint mixed with a few drops of dish soap, and let it dry completely. Then scratch with a toothpick.

Why does my paint bead up on the crayon?

Wax pushes water away. Stir a few drops of dish soap into the paint so it spreads, and add a second coat once the first is dry.

What can kids scratch with?

A wooden toothpick, a bamboo skewer, an opened paper clip, a used-up ballpoint pen or the end of a paintbrush. Younger children do best with the blunter tools.

Can I make scratch art without paint?

Yes: colour with bright crayons, cover them with a heavy layer of black crayon or oil pastel, and scratch through that.

What else is scratch art called?

Scratchboard, scraperboard (in the UK) or sgraffito, the artists’ name for scratching through one layer to show another.

Scratch a rocket on screen

Colour, paint it black, wait an hour in one tap and scratch. Then make the real card at the kitchen table.
