Today, we’re going to have some fun with science by exploring what happens when you mix baking soda and vinegar. These are safe to use, but remember, don’t taste them or touch your face while experimenting!
For our first experiment, we’ll see how baking soda reacts with different liquids. You can use liquids you have at home, but make sure to include vinegar. If you have different types of vinegar, try them all to see which one reacts the most!
Here are some liquids you might find at home: tap water, lemon juice, coffee, lime juice, and distilled vinegar. You can use a small paint palette or an ice cube tray for this experiment. Start by putting a little baking soda in each section. The more sections you have, the more liquids you can test!
First, let’s try tap water. It doesn’t do much with the baking soda. Next, add a few drops of lemon juice. Wow! It bubbles up! Lime juice is similar to lemon juice, so it should react too. And it does, even more than the lemon juice!
Now, let’s try coffee. Like water, it doesn’t react much. Finally, let’s test vinegar. It makes the biggest reaction with the baking soda!
Now that we know vinegar reacts the most with baking soda, let’s use this reaction for another experiment. You’ll need a small container, a straw, baking soda, vinegar, and some modeling clay.
First, seal the area around the straw with modeling clay so no gas escapes. Add some water to your container. When you mix baking soda and vinegar inside, the gas will push the water out through the straw. This can get messy, so try it outside, even if it’s raining!
Start by adding vinegar, then quickly add baking soda and close the lid. Watch the fizzy fountain!
For this experiment, we’ll use the gas from the baking soda and vinegar reaction to put out a candle. You’ll need vinegar, baking soda, a small glass, a funnel, a candle, and a lighter. Make sure an adult helps with the candle.
First, pour a little vinegar into the glass. Then quickly add baking soda. Place the funnel on top to catch the gas. Light the candle and hold it over the funnel. The gas will put out the flame!
In this experiment, we’ll make a cork pop using baking soda and vinegar. You’ll need a bottle, a cork, a funnel, vinegar, and baking soda. Be careful, as the cork can fly high!
First, use the funnel to add baking soda to the bottle. Then quickly pour in vinegar and put the cork in. Step back and watch the cork pop!
These experiments are a fun way to learn about science. You can also explore more about math, reading, and writing with the Kids Academy app. Have fun experimenting!
Observation Journal: Start a science journal to record your observations from each experiment. Draw pictures of what you see when you mix baking soda with different liquids. Write down which liquid made the most bubbles and why you think that happened. Share your journal with a friend or family member and explain your findings.
Bubble Race: Create a bubble race using different types of vinegar. Use small cups and place a spoonful of baking soda in each. Add a different type of vinegar to each cup (e.g., apple cider vinegar, white vinegar, balsamic vinegar) and see which one creates bubbles the fastest. Predict which vinegar will win the race before you start, and then discuss why some vinegars might react faster than others.
Everyday Reactions: Go on a scavenger hunt around your home to find other items that might react with baking soda. Try things like orange juice, soda, or even toothpaste. Make sure to ask an adult for permission before using any items. Record your results and think about why some items react and others don’t. Discuss with your family how these reactions might be similar to or different from the baking soda and vinegar reaction.

For today’s set of experiments, we’re going to explore the reaction between baking soda and vinegar. While both of these compounds are relatively safe, it’s important to remind young scientists not to taste or touch their faces with any of these chemicals.
For our first experiment, we’ll examine the reaction between baking soda and several different types of liquids. You can choose any liquids you have at home, but make sure to include some type of vinegar. If you have more than one type of vinegar, feel free to experiment with those to see which one creates the best reaction.
I’ve selected a few simple liquids that you can find at home: regular tap water, lemon juice, coffee, lime juice, and distilled vinegar. I’ll be using a small paint palette as my experiment plate, but an ice cube tray works well too. Let’s start by adding a small amount of baking soda to each compartment. The more compartments you have, the more liquids you can experiment with.
The tap water seems to absorb the baking soda without much of a reaction. Now, let’s add a few drops of lemon juice. We can see that the lemon juice causes quite a reaction with the baking soda. Since lime juice and lemon juice are similar, we expect the lime juice to have a similar reaction. The lime juice appears to be even more reactive than the lemon juice.
Now, let’s try some coffee. Just like the water, the coffee absorbs the baking soda but doesn’t produce much of a reaction. Lastly, let’s test our vinegar. The vinegar reacts the most with the baking soda.
Now that we know vinegar is the most reactive liquid with our baking soda, let’s gather some more materials and try another experiment.
Our next experiment will use the reaction we observed earlier. We’ll need a small container, a straw, baking soda, vinegar, and a small amount of modeling clay. First, cover the hole around the straw with modeling clay to prevent any gases from escaping. Next, add some water to your container. When we mix the baking soda and vinegar inside, the expanding gases will push the water down and out through the straw. This experiment can be messy, so we’ll head outside to test it out. It should work fine even on a rainy day.
First, we’ll add the vinegar, then quickly add the baking soda and screw on the lid.
The reaction between baking soda and vinegar creates carbon dioxide gas, which we’ll use to extinguish a candle. For this experiment, we’ll need vinegar, baking soda, a small glass, a funnel that fits over the glass, a candle, and a lighter. Make sure to have adult supervision when using flames.
First, add a small amount of vinegar to the glass. Then, we’ll quickly move through the next steps: add the baking soda, and the reaction will occur inside the jar. Quickly place the funnel on top to capture the carbon dioxide gas. Light the candle, hold it over the funnel, and we should see the flame extinguished by the expanding carbon dioxide gas.
For the next experiment, we’ll use a bottle cork, funnel, vinegar, and baking soda. This cork can pop quite high, so use caution. First, add the dry ingredients using the funnel. Then, quickly add the vinegar and insert the cork, stepping back immediately. This experiment may take a few minutes, so keep your distance.
