The chemical reaction between the baking powder and vinegar leads to the production of carbon dioxide gas. The carbon dioxide fills the body of the rocket until it is full and under pressure. At this point the carbon dioxide gas begins to escape downwards out the bottom of the rocket creating thrust. This pushes the rocket to fly upwards.
