Doing Work While Playing

Taking a queue from Google, I have come up with an idea (that I’d like to get paid for) for doing work while playing: Put seeds (grass, tree, flower, etc.) in pellets/paintballs, so when people are playing (practicing war ???), they can at least be doing something useful, like planting food. The pellets/paintballs (depends on what type of weapon you’re using) can be biodegradable, and when coming in contact with water (can you say rain?), melt, yielding up the see contained within.
