A mechanism controls the release of the gas formed by the chemical reaction and allows the gas to reach a high pressure inside the rocket prior to release.

1. A toy bottle rocket that uses a mixture of baking soda and vinegar to produce a propellant gas, the bottle rocket comprising: a bottle having a bottle mouth opening; an elongated tube, separate from the bottle, for holding baking soda while the tube is inserted into the mouth of the bottle, the tube having opposite end openings and an outer diameter that is less than the diameter of the bottle's mouth opening; a stopper member assembly having an end portion that is at least partially insertable into one open end of the tube, for closing that end of the tube and connecting the tube to the stopper member assembly, the stopper member assembly further including means for compressing another portion of the stopper member assembly along a lengthwise axis, to thereby expand the circumference of the stopper member assembly outwardly against the mouth opening of the bottle after the combined stopper member assembly and tube are together inserted into the mouth opening of the bottle, for increasing the friction between the stopper member assembly and the mouth opening, and to thereby create a higher resistance to gas pressure build-up inside the bottle when the baking soda is mixed with the vinegar.
