Want to launch your own mini rocket at home? 🚀 With just baking soda, vinegar, and a simple container, you can create an exciting chemical reaction that blasts a rocket into the air. It’s safe, fun, and a perfect science project for kids and curious minds.
What You’ll Need
- An empty plastic bottle (small soda bottle works best)
- Baking soda (2–3 tablespoons)
- Vinegar (½ cup)
- Tissue paper or napkin
- Cork or tight bottle cap
- Open outdoor space
Step-by-Step Instructions
1. Prepare the Baking Soda Packet
Wrap 2–3 tablespoons of baking soda inside a small piece of tissue. Twist the ends to make a little packet.
2. Add Vinegar to the Bottle
Pour about half a cup of vinegar into the plastic bottle.
3. Insert the Baking Soda Packet
Carefully drop the packet into the bottle.
4. Seal Quickly
Put the cork or cap tightly on the bottle and place it on the ground upside down (cap facing down).
5. Stand Back and Launch!
In just a few seconds, pressure will build up and your rocket will launch into the air.
Why Does It Work?
- Baking soda (a base) reacts with vinegar (an acid).
- This creates carbon dioxide gas (CO₂).
- The gas builds pressure inside the bottle until it explodes out, pushing the bottle upwards like a rocket.
Fun Variations
- Try different bottle sizes to see how high they go.
- Add food coloring to vinegar for a colorful splash.
- Create a launch pad with cardboard for more stability.
Safety Note ⚠️
Do this experiment outdoors only. Stand at a safe distance after sealing the bottle, and never point the rocket at people or animals.
Conclusion
The baking soda and vinegar rocket is a simple yet powerful way to learn about chemical reactions and gas pressure. Plus, it’s one of the most exciting backyard science experiments you can try at home.
