Get a bunch of little plastic cups, fill them with soil, and sprinkle some seeds in them. It doesn’t matter what kind of seeds you put in — they can be flowers, or fruit, or vegetables. After you put everything in the cups, put a little label on them with a message like “Make the world a better place. Plant me.” Then, go around your neighborhood, or any neighborhood for that matter, and simply place a cup on everybody’s doorstep. Theyll find the cup eventually, and who knows, maybe sooner or later youll notice new plants along your street!
