You can find directions
HERE to print out and include with your jars, if you like. If you can translate them into another language, I'd be happy to post them here as well.
This is what they say:
You hold in your hands a bit of world peace which, together with all the bits that everyone else will soon hold, can be opened and let loose on the world simultaneously to bring - you guessed it - world peace.
Store in a bright warm place. Kitchen windowsill works great. Hold often.
This jar is equipped to generate about three more jars of world peace each week. You may be able to care for yours to generate more. If you wish, you can pour a bit of it into more jars and pass each to a friend, acquaintance, or anyone really, with a copy of these directions.
Once all the bits of peace have been distributed, we will have a coordinated newscast for everyone in all languages throughout the world during a coordinated world minute for everyone to open their jars and let each of their pieces of peace out.
