Art School | Bleaching

by , posted on December 26th, 2012 in Art School, Science Fun




Today we are back in the kitchen for our art lesson, but it’s more to do with science than cooking for today’s cool project. We will learn natural ways to lighten color. Lemons, oranges, limes and other citrus fruits have high concentrations of citric acid. Citric acid is used for many things, it’s not only in food, but it can be added to foods for flavoring, it’s used in soaps, detergents, and also used to dye things. We will be using lemon juice as our alternative to bleach. Bleach is a chemical that can remove color or lighten something. But it’s not safe for kids, so we are substituting bleach with good old lemons.

Supplies: lemons, hand juicer, watercolor paper, watercolors, brush, pencil, water, bowl

You’ll want to juice 1-2 lemons depending on how many pieces you are painting. Once the lemons are juiced, set that aside and work on the drawings. Cut your watercolor paper into cards about 5.5 in by 4.5 in. Let your kids free draw whatever they’d like, it can be as simple as some shapes or with any details they’d like.

Once all your cards are drawn, start painting with watercolors. Be sure the entire card is painted so there’s not any white left. The darker the colors, the more you will see the contrast once the lemon juice is used.

When the paintings are finished set them aside until they are nice and dry.

Now it’s time to paint with the lemon juice. Using a brush, you can brush the lemon juice on in dots or lines. Some of my kids decided to do it haphazardly with some splotches here and there, and others wanted to be more specific with their lines making stripes or a grid. After the lemon juice is brushed on certain parts, let it sit for a 1-3 minutes and than blot with a paper towel to remove any excess juice.

You’ll see the transformation the most on the darker watercolors.

When complete, hang to admire how science and art have merged!
