Rocket propellant is mass that is stored in some form of propellant tank, prior to being used as the propulsive mass that is ejected from a rocket engine in the form of a fluid jet to produce thrust. A fuel propellant is often burned with an oxidizer propellant to produce large volumes of very hot gas. These gases expand and push on a nozzle, which accelerates them until they rush out of the back of the rocket at extremely high speed, creating thrust. Sometimes the propellant is not burned, but can be externally heated for more performance. For smaller attitude control thrusters, a compressed gas escapes the spacecraft through a propelling nozzle.

Chemical rocket propellants are most commonly used, which undergo exothermic chemical reactions to produce hot gas used by a rocket for propulsive purposes.

In ion propulsion, the propellant is made of electrically charged atoms (ions), which are electromagnetically pushed out of the back of the spacecraft. Magnetically accelerated ion drives are not usually considered to be rockets however, but a similar class of thrusters use electrical heating and magnetic nozzles.

Martin Stääf (born 13 November 1978), aka Liquid Stranger, is a Swedish-born electronic musician, described by Generation Bass as ”the epitome of Transnational Dubstep covering everything from Latin, Asian, Eastern European and Jamaican Dancehall dubs.” Martin Stääf is known for his experimental approach to composition where he merges genres to create a unique style of music. Martin Woods of Chillbase describes Liquid Stranger's music as a “unique blend of Ambience, Big Band Jazz, Dubstep and Psychedelica drizzled over electronic Dub Reggae grooves.” Stääf lives in Scottsdale, Arizona.

Martin Stääf was born 13 November 1978 in Varberg on the Swedish West Coast. He started playing the piano and did classical piano concerts between the ages of 6-8. Stääf started experimenting with synthesizers in the mid 80s and abandoned the classical music world to spend the next 10 years producing his own material. Stääf states: ”I never thought about releasing any of my music until I was 17. Then, all of a sudden, it was time to get a job and I realized that there was nothing else I wanted to do at that time than making music.”

Jeffrey Vinokur (born August 24, 1990), who also goes by the stage name The Dancing Scientist, is an American science educator known for combining the hip hop dance genre of popping with live science demonstrations. He has performed his science and dance act on America's Got Talent and at venues such as the Liberty Science Center, the Maryland Science Center, the Saint Louis Science Center, the World Science Festival, and the grand opening of the Wisconsin Institutes for Discovery. He has also appeared on CW 11 NewsCBS News, and Fox 2 News. His mentors include physicist Clint Sprott. In 2009 he founded the Madison Dance Conference at the University of Wisconsin–Madison, and his online Popping videos have accumulated over 10 million hits.

Jeffrey Vinokur was born in 1990 and raised in Montvale, New Jersey to Russian parents. He developed an interest in science while attending school, first at Fieldstone Middle School and then Pascack Hills High School.

While a senior in high school he began watching online videos and DVDs on hip hop dancing, and after six months of practice traveled to New York City, where he learned the sub-genre of hip-hop dancing "popping" from dancers such as Jazzy J of The Electric Boogaloos, Dementia of ABM Crew, Future Ninja of House of Ninja, and Hit Master Fish of G-Style. Afterwards he began posting instructional dance videos on YouTube under the username "TheRussianTiger," and the videos have since garnered millions of views.
