Give each player a drinking straw. Divide the den into two teams. Give the first player on each team a square of tissue paper. On signal, he tries to lift the tissue paper off the table by inhaling through the straw and pass it to the next member of his team without dropping it. The next player must take the tissue paper using the straw and pass it to the next team member. If the paper falls, it must be picked up with the straw.
