embargo was skyrocketing energy prices as a result of limited supply and heavy demand. Rationing went into effect‚ with supplies of petroleum products being carefully doled out with ration cards and flag systems‚ in which people could take turns buying gas and other fuels on the basis of license plate numbers.

SHAMINMENISHA How Water Rockets Work A water rocket works using the same principles as other rockets. There are three main forces in action: thrust (Fapp)‚ drag (Ffr) and weight (w=mg). The water‚ which is forced out by the difference between internal and atmospheric pressure‚ is a reaction mass that provides the thrust. All rockets have a reaction mass‚ which can vary from hot gasses that are expelled when a fuel is burnt (in the Space Shuttle’s SRB’s for example) to water in a water rocket. The
