Making Carbon Dioxide at Home




Introduction: Making Carbon Dioxide at Home

This tutorial will teach you the very simple procedure to trap a balloon of carbon dioxide using only common household kitchen supplies.

Step 1: What You Will Need

You won't need much to do this experiment, but you will need these:
1. Narrow-mouthed vase or bottle
2. Baking soda
3. Spoon
4. Vinegar
5. A balloon

Step 2: Step One: Fill the Bottle

Take the spoon and put in some baking soda. Doesn't really matter how much, just make sure you've got a couple of spoonfuls.

Step 3: Step Two: Fill the Balloon

First, fill the balloon with air like the first picture indicates. Then stretch it over the mouth of the vinegar bottle and fill it with vinegar. Pinch it closed and hold it until the next step.

Step 4: Step Three: Prepare for the Reaction

Carefully stretch the balloon over the mouth of the bottle- don't dump the vinegar in yet! Then carefully move the setup into a sink and set the vase down.

Step 5: Step Four: Perform the Reaction

With your hand on the mouth of the bottle, carefully tip the balloon over, dumping in the vinegar. Watch as the balloon fills with a gas. That gas is a good portion carbon dioxide. Although it isn't pure because of the air in the bottle, it's enough to extinguish a candle.

You're finished! Clean up your mess and make sure to favorite this tutorial!

    Thank you for sharing this!

    Is there any way you could post the chemical reactions going on here as well?

    (This is a very quick explanation and process, and I really appreciate it. I am inferring that the Carbon from Sodium Bicarbonate (NaHCO3) is reacting with Oxygen in the Vinegar (CH3COOH), to form Carbon Dioxide (CO2). However I am curious, what is the substance left in the vial!?!?)
