Yay! My pawrents have left Hawaii! Aloha Hawaii!! Guess what? My pawrents sent me a postcard - they really do miss me! The picture shown is of the "spouting horn" in Kauai. The water spouts out of an underwater lava tube. When the waves crash into the shore they push water into one end of the tube which thrusts water out of the other end - this end is on dry land. Aloha Hawaii.
