Take back the pavement. That’s one of the slogans of a new campaign by Lush, makers of handmade cosmetics.

From now until 26, Lush stores across Canada are giving out seed bombs. The idea is to throw the seed bomb somewhere that needs colourful flowers (vacant lots, empty planter boxes and alleyways), and watch the transformation.

They call it a random act of kindness to Mother Nature, and it’s to honour Earth Day on April 22.

Seed bombs are made of soil, seeds, water and clay and rolled into a small ball.
