On a table inside the hangar, Dr. Bill Gutman, Director of Aerospace Operations at Spaceport America, explained the various materials used in spacecraft design, passing around cubes of aluminium, magnesium, and tungsten for guests to hold. Periodically, he would lead his audience outside, launching a water bottle with water and air pressure alone, then another water bottle with a squirt of pure alcohol and a spark. The whole affair felt very much like a guest speaker exposition for a middle school, or a field trip to a children's museum. ¡Explora!, a children's museum in Albuquerque, had multiple activity tables set up in the hangar, too. Some were related: construct a paper glider to float up this plastic tube over a fan pointed upwards, and some weren't, like a table covered in microscopes.
