Chia Pets...on Acid

Remember Grandma-approved eco-friendly mud graffiti?

London native Helen Nodding has taken a similar approach: non-destructive moss graffiti. Helen was inspired by the cold hard steel, glass, and concrete of the city:

"I'm always cheered up when I see weeds pushing through a crack in a paving stone, or grass growing somewhere where nobody had planned for it to be."

Inspired to try-it-yourself? Helen was kind enough to post an Instructable. Scroll all the way down for her recipe, via Supernaturale.

Moss Graffiti Recipe (makes several small pieces or 1 large piece of graffiti):

1 can of beer

1/2 teaspoon sugar

Several clumps garden moss, cleaned of dirt and rocks

You will also need a plastic container (with lid),

a blender and a paintbrush

To begin the recipe, first of all gather together several clumps of moss (moss can usually be found in moist, shady places) and crumble them into a blender. Then add the beer and sugar and blend just long enough to create a smooth, creamy consistency. Now pour the mixture into a plastic container.

Find a suitable damp and shady wall on to which you can apply your moss milkshake. Paint your chosen design onto the wall (either free-hand or using a stencil). If possible try to return to the area over the following weeks to ensure that the mixture is kept moist. Soon the bits of blended moss should begin to re-couperate into a whole rooted plant – maintaining your chosen design before eventually colonising the whole area.
