I don't know what it is about bubbles that makes kids so happy! I give them bubbles and they scream like I just told them we are going to Disneyworld. Then they are in a trance watching each other make bubbles. Elizabeth summed it up well by saying "There is nothing more beautiful than watching bubbles." Seriously. My secret to calming that inevitable late afternoon/evening storm of tantrums: bubbles, man, bubbles.
