Shaving cream marbling for kids: swirl, press, scrape

Art technique

Marbled paper from a can of shaving foam

Spread shaving foam in a tray, drop food colouring on it and drag a toothpick through to pull the colour into veins. Press paper on top, scrape the foam away, and the marbled pattern stays on the paper.

Quick facts

Age

4+ for swirling and printing

Time

30 minutes, plus an hour to dry

Mess

High, but it is soap: it wipes up

Adult needed

Yes: to spread the foam and handle the food colouring

You need (cost)

Plain white shaving foam, food colouring, card, a ruler

On screen / for real

Both

What you'll make

Sheets of marbled paper with soft veins and swirls of colour, good for cards, bookmarks, gift tags or the cover of a notebook. One tray of foam gives two or three prints.

In Extreme Drawing

Science tab → Shaving foam. Drag to squirt a thick white bed of stiff foam: the same foam as soap suds, whipped stiffer. It stands and only collapses slowly.
Science tab → Food colouring (red, blue, green or yellow). Drip a few drops on the foam. They stay where they land, as blobs of colour, instead of spreading as they would on a puddle.
Craft tab → Poke → Toothpick or Skewer (in the full toolbox). Draw it through the blobs: the colour is pulled out into streaks and veins and the foam closes in behind the stick. The colours stay apart; they don’t turn to mud.
Press and scrape. Hold the Hand still on the foam for a few seconds to press the colour into the paper, then drag the Scraper (Toolbox) across. The foam comes up on the blade and the marbled print is left on the paper.

Also try: a sticker under the foam (in the full toolbox). The foam lies on the sticker, so its colour never reaches the paper underneath.

For real

Do it for real

You need

Plain white shaving foam (foam, not gel)
Liquid food colouring or liquid watercolour
A baking tray or plastic tray
A toothpick, skewer or fork
Thick paper or card, a little smaller than the tray
A ruler or an old plastic card for scraping
Kitchen paper and an apron

Step by step

Make a foam bed
An adult sprays a layer of foam about 2 cm thick into the tray. Smooth the top flat with the ruler.
Drop the colours
Add drops of two or three colours across the foam, with gaps between them.
Swirl gently
Drag the toothpick through in lines, waves or loops. Stop while you can still see separate colours: too much swirling turns it brown.
Press the paper
Lay the card flat on the foam and pat it gently all over. Don’t push it down into the foam.
Lift and scrape
Peel the card off, lay it foam side up and scrape the foam away in one sweep with the ruler.
Let it dry
Leave it flat for about an hour. The soap dries invisibly and the colour stays.

Variations to try

Easter eggs

Cut egg shapes out of card before you print, for a row of marbled Easter eggs on the window.

Autumn leaves

Red, orange and yellow foam prints, cut into leaf shapes once dry.

Cards and bookmarks

Print a whole sheet, then cut it up: every piece has a different pattern.

One colour, many shades

Use only blue, with a lot in some places and a little in others. The veins show up even better.

In the app vs on paper

On screen

The paper is already under the foam: you press with your hand and scrape the foam off the page. Colour is only moved, never made or lost, so what the paper gets, the foam loses. Shaving foam, food colouring, the hand and the scraper are free; the toothpick is in the full toolbox.

On real paper

You lay the paper on top of the foam and lift it off. You can print two or three sheets from one tray, each paler than the last, and the leftover foam is wonderful to squish (then wash your hands).

Why the colour stays put in foam

Foam is millions of tiny bubbles. Together they are stiff enough to hold a drop of colour still, so it stays exactly where you put it until a stick drags it along.

For grown-ups. Shaving foam is gas held in thin films of soapy water. It behaves like a soft solid with a yield stress: it keeps its shape, and a drop of dye in place, until it is sheared. A toothpick shears a narrow path and stretches each blob into a thin streak, the same “tine stroke” marblers make with a stylus. The dye sits in the water of the bubble walls; where the paper touches, it soaks up colour from the surface layer, and the foam scrapes off because it never soaked in. Compare magic milk, where soap makes the colour move by itself.

Try next: what do you predict?

One minute or five?

Does the print get stronger if the card waits on the foam longer?

A second print?

Can you print again from the same foam? How different does it look?

Two colours or six?

Which gives the prettiest veins before it turns brown?

Foam or milk?

In magic milk the colours move on their own. Why don’t they in foam?

For teachers

In the classroom

Shaving-foam marbling fits KS1 and KS2 art (printing and pattern) and a conversation about solids, liquids and in-between things like foam. Pair it with magic milk to compare colour that stays put with colour that rushes away.

States of matter lesson Ideas for teachers

Questions parents ask

What kind of shaving cream works for marbling?

Plain white shaving foam that comes out of the can as foam. Gel only turns to foam when rubbed, so it is hard to spread evenly. Foam for sensitive skin is kindest to hands.

Can you use paint instead of food colouring?

Liquid watercolour works well. Thick paint sits in lumps on top and doesn’t soak into the paper as easily.

Why did my marbling turn brown?

Too much swirling mixes the colours into one. Drag the stick through only a few times, and pick colours that look good together, such as blue and yellow.

Does the colour come off the paper?

No: it soaks into the paper and stays when the foam is scraped off. Let it dry flat before you stack the sheets.

Is it the same as magic milk?

Both float colour on something white, but on milk the soap makes the colour rush away by itself. In foam the colour stays put until you move it.

Swirl the foam on screen

Squirt a bed of shaving foam, drip in food colouring, swirl and scrape, all without a tray to wash up. Then try the real one.
