Baking Soda and Vinegar Rocket Experiment: Launching a Simple Rocket

The Baking Soda and Vinegar Rocket experiment is an exciting and hands-on activity that demonstrates the reaction between baking soda and vinegar to create a gas that propels a simple rocket into the air. This experiment provides a fun way to learn about chemical reactions and the principles of propulsion.

Baking Soda and Vinegar Rocket Experiment

Materials Needed for this science experiment:

  1. Film canister with a tight-fitting lid or plastic bottle (clear if possible)
  2. Baking soda
  3. Vinegar
  4. Tissue or paper towel
  5. Protective cover for the workspace
  6. Optional: Food coloring


1. Set Up the Workspace: Choose a clean and open area for the experiment. Place a protective cover on the surface to catch any spills.

2. Prepare the Film Canister: Open the film canister and place a small amount of baking soda (about 1 teaspoon) in the canister’s bottom. If you want to add a colorful effect, you can add a drop of food coloring to the baking soda.

3. Add Vinegar: Pour vinegar (about 1-2 tablespoons) into a small container. Wrap a tissue or paper towel around the mouth of the film canister, making sure it doesn’t block the opening.

4. Assemble the Rocket: Quickly place the lid on the film canister, sealing it tightly. Make sure the tissue or paper towel is securely in place, acting as a plug.

5. Position the Rocket: Place the film canister rocket on a flat surface, lid side down. Step back to a safe distance.

6. Lift the Rocket: Lift the film canister slightly and turn it upside down so that the vinegar comes into contact with the baking soda.

7. Launch the Rocket: Set the canister back down and stand clear. The chemical reaction between the baking soda and vinegar will produce carbon dioxide gas, building up pressure inside the canister. Eventually, the pressure will cause the lid to pop off, and the rocket will launch into the air.

8. Observe and Enjoy: Watch in amazement as your rocket launches into the air with a fizzy propulsion. The reaction between the baking soda and vinegar generates the gas that propels the rocket.

9. Experiment with Variations: You can experiment with different amounts of baking soda and vinegar to see how they affect the rocket’s launch height and intensity.

10. Reflect on Chemical Reactions: Discuss with children how the reaction between baking soda (a base) and vinegar (an acid) produces carbon dioxide gas. The gas builds up pressure inside the canister, causing the lid to pop off and propelling the rocket.

11. Safety Note: Always launch the rocket outdoors in an open area. Make sure to stand clear and avoid pointing the rocket at people or animals.

The Baking Soda and Vinegar Rocket experiment is a thrilling and educational way to explore the principles of chemical reactions and propulsion. It’s a fantastic opportunity for children to engage with science in a hands-on and visually impressive manner.
