They incorporated commonly available fireworks such as cherry bombs into their rockets, and Parsons suggested using glue as a binding agent to increase the rocket fuel's stability.

He flourished academically, becoming editor of the school's newspaper El Universitano and winning an award for literary excellence; teachers who had trained at the nearby California Institute of Technology Caltech honed his attentions on the study of chemistry.
Parsons soon constructed a solid-fuel rocket engineand with Forman corresponded with pioneer rocket engineers including Robert H. Parsons and von Braun had hours of telephone conversations about rocketry in their respective countries as well as their own research.
John Avenue, where he continued to pursue his interests in literature and poetry. He saved money in the hope of continuing his academic studies and began a degree in chemistry at Stanford Universitybut found the tuition fees unaffordable and returned to Pasadena.
JPL marks this experiment as its foundation. Malina wrote in that the self-educated Parsons "lacked the discipline of a formal higher education, [but] had an uninhibited and fruitful imagination. Landis writes that their creativity "kept Malina focused toward building actual rocket engines, not just solving equations on paper".
They often socialized, smoking marijuana and drinking, while Malina and Parsons set about writing a semiautobiographical science fiction screenplay they planned to pitch to Hollywood with strong anti-capitalist and pacifist themes. Left foreground to right: Parsons met Helen Northrup at a local church dance and proposed marriage in July At one point he pawned Helen's engagement ring, and he often asked her family for loans.

Consider: a single light-year is an inconceivable abyss. Denumerable but inconceivable. At an ordinary speed — say, a reasonable pace for a car in a megalopolitan traffic, two kilometers per minute — you would consume almost nine million years in crossing it.
