20 Baking Soda Experiments for Kids

Kids love science experiments and this really is the perfect way to keep your little scientists busy while developing a sense of wonder. And when it comes to baking soda experiments for kids, the list is truly fascinating!

The sizzle, bubbles, eruptions and excitement of watching a chemical reaction—all while being child-safe—before your eyes is nothing short of thrilling.

(Check out the Screaming Cup science experiment we wrote about a while back.)

And that is why all baking Experiments with baking soda are very successful among children of all ages.

Now, before we get started on this amazing list of fun things you can make with baking soda, here’s a little science on the wonderful chemical reaction used in all the experiments.

The science of cooking Soda eruptions

From a chemical point of view, baking soda is a base. When mixed with an acid such as vinegar, they react to create a rather spectacular show of carbon dioxide eruption.

Although water is also a byproduct of the reaction, it presents a far less spectacular show than the explosion of carbon dioxide, which is a gas.

Technically, this is what happens:

Sodium bicarbonate + acetic acid -> Sodium acetate + Carbon dioxide + water

C2H4O2 + NaHCO3 -> NaC2H3O2 + CO2 + H2O

The above equation for acetic acid and sodium bicarbonate explains the scientific reaction between baking soda and vinegar. Now that you understand what’s going on here, let’s jump right into the list of insanely cool things you can make with baking soda.

Fun and easy baking soda experiments for kids

1. Volcano eruption

This is one of our all-time favorites and we’ve made it almost a million times with the kids. This is a great science experiment for kids if they team up with the geology units.

In addition to baking soda and vinegar, you will need:

• Dish soap
• Orange food coloring
• Old plastic bottle
• Plaster of Paris/plaster

Step 1: Take an old plastic bottle and cover it with plaster or plaster of paris to make it look like a mountain. Let it dry!

Step 2: Mix food coloring and dishwashing liquid with vinegar. Leave it aside!

Step 3: Finally, add a handful of baking soda to your volcanic mountain.

Step 4: Pour vinegar, dishwashing liquid and food coloring into the bottle to see your very own erupting volcano.

2. Hatching of eggs

This is a great science project that can keep younger kids busy for hours. Let your kids hatch the eggs of their favorite animals with this fun activity.

Such hands-on activities perfectly develop children’s scientific acumen and interest them in STEM studies.

3. Potion that oozes blood

Now, this baking soda and vinegar experiment sounds both gross and bad, making it a surefire hit with kids and one of kids’ favorite Halloween activities. This is one of the most fantastic and coolest things you can make with baking soda.

All you have to do is replace the vinegar with tomato puree.

Step 1: Take a cauldron (or glass) and add tomato puree to it.

Step 2: Using a spoon, add the baking soda to the glass and stir it.

Your horrible bloody potion is ready!!

This potion will ooze, not erupt like a volcano. Can you guess why?

5. Acid Scientists

Since we’re taking part in fun STEM activities, why not turn your kids into little scientists! The task is to find out which of the following liquids are acidic.

Tell your kids that they don’t have a litmus test (indicator strips), but they can raid your pantry. Here’s how to complete this scientific study.

You will need:

• Oil
• Lemon juice
• Glycerin
• Orange juice
• Mold for ice cubes
• Baking soda
• Pipettes
• Paper and pencil

Step 1: Add 1 tsp. soda into ice cube trays.

Step 2: Test the liquid by adding a few drops of it with a pipette to the baking soda.

Write down the liquids that reacted and which did not. Those that have reacted with baking soda are acidic in nature.

6. Car with baking soda

Have fun with this amazing engineering project for kids, experimenting with baking soda and vinegar to create a baking soda car.

7. Wizard Potions

Do you have a potter’s head at home? How about brewing a potion that changes color? What you will need:

• Red cabbage
• Baking soda
• Vinegar
• Dish soap
• Glass/cauldron

Step 1: Make red cabbage juice by mixing it with water in a blender.

Step 2: Sieve the mixture to get red cabbage without lumps of juice.

Step 3: Pour the red cabbage juice into the cauldron. Add detergent to the juice and mix.

Step 4. Add baking soda to cabbage juice and mix. Does it change color?

Step 5: Now when you observe the color change, add vinegar to the mixture and stir.

Your magic color changing potion is ready! Watch for the color change.. The exploding fizzy concoction is nothing short of spectacular and sure to excite your Potter lover!

8. Make fizzy paint.

Another fun thing you can do with baking soda is fizzy paint.

Step 1. Mix equal parts baking soda and water.

Step 2: Add food coloring to the mixture to make fizzy paint.

Step 3. Using a brush, draw a picture on the sheet with sparkling paint.

Step 4: Using an eyedropper, add vinegar to the painting to watch it fizz.

Viola! Your painting sizzles! Allow the artwork to dry before displaying.

9. Poppers with baking soda

One of the funnest things you can do with baking soda is make loud poppers. They are so easy to make and super fun. What you will need:

• Vinegar
• Baking soda
• Dish-cloth
• Zippered package

Step 1: Take a zip lock bag and add vinegar to one quarter of the bag and seal it.
