  1. Gather the materials

    Get an empty, clean soda bottle, liquid dish soap, a small cup, a packet of active yeast, a pair of safety goggles, a small funnel and a bottle of hydrogen peroxide. Standard hydrogen peroxide works, but 8 percent hydrogen peroxide, which can be found at a beauty supply store, produces a stronger reaction.

  2. Mix the soap and hydrogen peroxide

    Put on your safety goggles. Add the soap and hydrogen peroxide to the soda bottle. Swirl the bottle to combine the liquids. Place the soda bottle in a wide basin or sink.

  3. Prepare the yeast

    Fill the cup with warm water. Pour the packet of yeast into the cup, and stir until the yeast is evenly distributed throughout the water. Let the yeast rest for about five minutes.

  4. Add the yeast to the soap and hydrogen peroxide

    Place the funnel in the mouth of the soda bottle, and pour the yeast solution into the funnel. Remove the funnel, and step back from the reaction.
