Using scissors, cut three to four 12-inch pieces of ribbon. Staple the ribbons onto the top of a basic cork. Set the cork aside.
Place a funnel into the opening of a plastic water bottle.
Pour 1/2 cup of baking soda into the bottle through the funnel. Tap the funnel to ensure that all of the baking soda entered the bottle.
Pour 1 cup of white vinegar into the bottle through the funnel. Tightly and quickly plug the opening of the bottle. Push the cork deeply into the bottle.
Shakeu the bottle vigorously, and hold the bottle so that the cork is facing straight up and away from you. The plugged cork with attached ribbons will shoot off into the sky.
