The painting that disappears

Painting on paper leaves you with an object. A sheet that needs somewhere to dry, then somewhere to live, then a decision about whether it is one of the ones you keep.

Water Painting Outside does not produce one. The brush goes on wet, the mark shows up dark against the surface, and then it lightens until there is nothing there.

What it takes

A small bowl of water and a wide brush. That is the whole list.

You also need an outdoor surface that water shows up on. Paving, a wall, a fence panel, the flat side of a planter. Somewhere the wet patch reads clearly against the dry surface around it.

The activity is listed at 15 to 30 minutes. That is an estimate of the activity rather than a promise about how long anybody will stay with it.

Setting it out

Put a small amount of water in a wide-based bowl that sits steadily, and stand it on flat ground away from where the child is actually painting, so the bowl is not underfoot mid-stroke.

Pick the spot before you fill anything. Away from steps and away from anywhere with traffic. Check the weather and the surface temperature first, and avoid anything hot underfoot or already slippery. Wet ground can be slippery underfoot, so clear spills as they happen rather than at the end.

An adult stays within arm’s reach of a two or three year old in an outdoor space that is not enclosed. Younger children need direct supervision throughout. Nobody is left outdoors alone, and nobody is left alone near the water.

Then show them once. Dip the brush, press it against the surface, lift it off. Refill the bowl when it runs low.

What actually happens

The first mark is the interesting bit. Water on a dry surface goes noticeably darker than everything around it, so a brushstroke reads almost like paint.

Then it starts to go. The mark lightens as it dries, until the surface looks the way it did before. How long that takes depends on the day, and it is not something to plan around.

Which sets up the thing this activity does that paper cannot. You can paint over the same patch again. You can chase a mark and try to go over it before it vanishes. You can write a name and watch what happens to it as it dries.

Nothing to keep

At the end there is no wet sheet, no drying rack, no decision about what to do with it.

That cuts both ways and it is worth knowing before you start. There is nothing to show anybody afterwards, and nothing to photograph unless you do it while the mark is still dark.

Stop when their interest moves on to something else. The marks will finish drying whether anybody is watching them or not.
