May21_144 Preparing for the launch. The blue barrel holds water used for the bottle rockets. May21_145 The teenagers occasionally got a chance to launch a rocket. May21_146 Water is added to the bottle then placed on the launcher. The neck of the bottle is pressed down over an o-ring, then the release clamp is slid over the neck's flange to hold the rocket until ready to launch. May21_147 A tire pump is used to pump the bottle up to 60 psi. The lighter weight kids needed help getting the pressure up. Note the boy on the left has a 3 bottle rocket. The longer rocket with fins doesn't tumble like the single bottles do. May21_148 A trail of water is left behind as the bottle rocket takes off. May21_149 One rocket is on the launcher. Another is being placed on the launcher. May21_150 A closeup of the launcher. May21_151 A dad helps a future space scientist get the bottle pressure to 60 psi. May21_152 A bottle is caught in action. The rocket is so fast that a picture like this is hard to get. May21_153 A beautiful model of the Space Shuttle. May21_154 Checking out the launchers. May21_155 This youngster is being helped by a dad. May21_156 The Space Shuttle is ready to launch. Note that the bottle rocket nozzle is not in the center of gravity. The rocket went into the crowd of people, not into the air. May21_157 Many of the rockets were just plain bottles, but some were dressed with fins and port holes. May21_158 There was quite a crowd, with a waiting line behind each launcher. May21_160 The rocket was just launched. May21_161 Another rocket just took off. May21_162 Trying to get the pressure to 60 psi.
