At the end of the meal the children are invited to hunt for the Afikoman (the piece of matzah that was hidden earlier) and it is redeemed from the children who have found it, since it is necessary to have this taste of matzah as the last taste at the end of the meal. One way of redeeming it is to ask the children to name an organization that is working for social justice, freedom, peace, or healing of the earth, and the adults agree to contribute to that group in accordance with their own means.] [The Afikoman is distributed among the Seder company, and every one eats a bite of it.]
