Kids (with the help of adults) assembled small rockets. Later those rockets were launched so that each kid could marvel at his or her own rocket's flight.

A team of two boys glued pieces of rockets together.

A man asked two girls which one would like to volunteer to press the button to launch rockets.

The test rockets were launched using compressed air. A blue hose led compressed air to an array of electrically actuated valves. That way, only one rocket could be launched at a time.
