You learn as you go. Now I can identify meteorites and name the constellations like Orion. It was strange to see other moons and suns, not just the ones that we know.
After the shows we were just in time to make and launch our own rockets. It works on the principle of Newton’s third law, that every action has an equal and opposite reaction. We took a large plastic bottle and they showed us how to make it aerodynamic with wings, which we designed and painted.
For the launch outside they half filled the rocket with water and launched it with compressed air. Mine went hundreds of yards into the air and hit the weather station. It’s the oldest in the world so just as well it survived my rocket.
In the exhibition area we learned about all the people who went to the Moon while my little sister squished aliens in a video game in the children’s room and my brothers dressed up as astronauts and guided a rocket through space. Then they had their photos taken on the Moon. Wish they’d stayed there.
