FIRST PHOTO: Carden Academy of Maui 7th-graders Tiana Wetter, 12, (left) and Isabel Reithbrock, 12, pour a measure of water into their bottle rocket Saturday morning during the Maui Regional Science Olympiad Tournament at the University of Hawaii Maui College. The girls said they made their rocket "Isiana" out of two plastic bottles, PVC pipe, a dog's chew toy, tape and pieces of plastic snipped from a science folder.
SECOND PHOTO: The rocket launched with an explosion of water and air pressure but didn't soar as high as expected. "We should have used less water," Isabel said.
THIRD PHOTO: Lokelani Intermediate School 8th-grader Aaron Gilo, 13, checks on the increasing lean of his team's tower as the stress of weight is slowly added during Saturday's tower-building competition. Aaron and classmate Ryan Laberinto, 13, built the tower in two weeks. It supported 17 pounds before failing under the weight.
