This is some of the most clever art I’ve seen in a while. Using plants and soap to make the cities more eco-conscience, it’s brilliant!! I really hope this catches on and becomes popular. So, even though there might be legal consequences for green-tagging (can they really arrest you for washing a wall?), I’m going to do this.
3 handfuls of moss (preferably with most dirt washed off)
3 cups warm water
2 tablespoons water retention gel
1/2 cup buttermilk
Add all to blender and blend 2-5 minutes (until gel forms)
Transfer to bucket
Paint onto wood or rough concrete
Come back weekly to mist with water
Watch it grow.
Just clean things you find caked with dirt in artistic fashions.
you can use:
soap and brush
water pressure cleaners
your fingers (sometimes)
