The Science Behind Dancing Raisins

Are you wondering how raisins can dance? The secret lies in the interaction between the raisins and a fizzy liquid, like soda or a mixture of vinegar and baking soda.

When you place raisins in a carbonated liquid, the carbon dioxide bubbles attach to the wrinkles and irregular shapes – the rough surface of the raisins – making them buoyant. 

As more bubbles accumulate, the raisins rise to the surface. Once they reach the top, the bubbles pop, and the raisins sink back down.

This continuous process of rising and sinking creates the appearance of Dancing Raisins.

Here are the key scientific principles behind the dancing raisins phenomenon:

  • Buoyancy: When the tiny bubbles attach to the raisins, they become less dense compared to the liquid, making them float.
  • Carbon dioxide: In soda, CO2 is already dissolved in the liquid. In a baking soda and vinegar mixture, the reaction creates CO2 gas that forms bubbles.

History Of Dancing Raisins

Dancing raisins have been a popular science experiment for many years because it appeals to kids and adults alike!

The experiment demonstrates the principles of density, buoyancy, and chemical reactions, making it a popular (and safe) choice for classroom activities and at-home science exploration.

While it’s difficult to pinpoint exactly when the dancing raisins experiment first emerged, its enduring popularity attests to its ability to spark curiosity and teach fundamental scientific concepts.

Supplies Needed For Dancing Raisins Science Experiment 

You only need a few ingredients and supplies to do this easy science experiment that will enthrall kids of all ages!

  • A clear carbonated beverage – carbonated water or a clear-colored soda or soft drink (like Sprite or 7-UP)
  • Raisins – fresh works best
  • 2 to 3 clear glasses – depending on how many versions of the experiment you want to run
  • Tray – to catch any overflow (optional)

How To Make Dancing Raisins Experiment

Here’s how to set up and conduct the dancing raisins experiment:

Step 1

Fill a clear glass 3/4 full with the club soda or clear soda.

Step 2

Drop in the raisins. Observe and record what happens. Do they sink or do they float?

Step 3

Observe the process! Watch as the raisins begin to rise and fall, appearing to “dance” in the glass.

Be patient. It may take a few minutes for them to start ‘dancing’.

Step 4

Experiment further. If you prepared multiple glasses, try using plain water or different types of carbonated beverages and compare the results to see which one creates the most “dancing” raisins.

Now that everything is set up enjoy your dancing raisins experiment and have fun exploring the concepts of density and buoyancy!

Dancing Raisins Experiment Recipe Notes And Tips

  • Reminder: This experiment works best if you use soda that has been unopened previous to doing this experiment.
  • Raisins are sticky and are usually stuck together in clumps. Be sure to separate them before dropping them in the soda, or they won’t ‘dance’. Small to medium raisins work best.

Dancing Raisins Experiment Variations and Extension Ideas

  • Experiment with different brands and kinds of soda and see which one works the best.
  • Try the same experiment with blueberries or grapes. They do not have shriveled skin, so will they rise to the top in the soda the same way raisins do?
  • Use other types of food, such as uncooked pasta shapes, corn kernels, lentils, or rice, to drop in the soda. We tried white rice, but it did not work for us. Next time we should try brown rice. 😉
  • In place of soda, use baking soda dissolved in water and vinegar. Add two teaspoons of soda to a half cup of water. Add 5 – 7 raisins to the soda/water mixture. Very slowly, pour in a tablespoon of vinegar. Watch the raisins start to dance. TIP: Place your glass or cup on a baking sheet or shallow dish before adding the vinegar. The baking soda and vinegar could potentially make a little bit of a mess.

Different Ingredients

You can try out different variations of the dancing raisins experiment by changing the ingredients. Instead of using raisins, you could test other lightweight objects like popcorn kernels or small pasta shapes. How does their behavior differ in the reaction of baking soda and vinegar?

Another idea is to use different types of vinegar, such as white vinegar, apple cider vinegar, or even lemon juice. Observe if the change in acidity affects the reaction and the resulting “dance” of the raisins or other objects.

Observations and Analysis

Expected Results

During the dancing raisins experiment, you can expect to see raisins initially sinking to the bottom of the glass. After a short while, the raisins will start to rise to the surface, appearing to dance. Once they reach the surface, they’ll fall back down, and the process will repeat.

Explanation of Observations

The reason behind the dancing raisins phenomenon is the formation of gas bubbles around the raisins. In the version of the experiment with soda, carbon dioxide bubbles are responsible for the movement. When you pour the soda into the glass, you’ll notice fizzing and bubbles forming, which is a result of the carbon dioxide gas being released from the liquid.

As the raisins sit in the soda, small carbon dioxide bubbles form on their surfaces. These bubbles act like tiny life jackets, causing the raisins to become buoyant and rise to the top of the glass. Once there, the bubbles burst, and the raisins lose their buoyancy, falling back down.

Baking Soda and Vinegar Version

In the baking soda and vinegar versions, a similar process occurs. When you add vinegar to a glass with warm water and baking soda, a chemical reaction takes place, producing carbon dioxide gas (it looks like carbon dioxide fizz). As with the soda version, bubbles of carbon dioxide form around the raisins, making them rise and fall.

By observing the dancing raisins, you’ll gain a better understanding of how gas bubbles can affect an object’s buoyancy. This simple yet engaging experiment demonstrates fundamental concepts of physics and chemistry in an entertaining way.

Educational Connections

The dancing raisins experiment is a fun science experiment and an excellent opportunity to connect this fun activity with various educational subjects. For example:

  • Science: Teach your kids about gas, buoyancy, and density. Explain how the carbon dioxide gas produced from the reaction between baking soda and vinegar causes the raisins to rise, and how the release of these gas bubbles makes the raisins “dance.”
  • Observation skills: Encourage your kids to observe the changes during the experiment closely. What happens when you first combine the ingredients? How do the raisins behave during the reaction? Prompt them to write down or discuss their observations.
  • Creative writing: Let your kids write a short story or a poem inspired by the dancing raisins. They can engage their imagination, putting themselves in the shoes of the raisins or creating a fantasy world where dancing raisins come to life.

Remember to encourage curiosity and exploration during these variations and connections. By doing so, you’ll create a fun and rewarding learning experience for your kids.

Safety Precautions

When performing the dancing raisins experiment, there are a few safety precautions to keep in mind. First, make sure you have a clean and clutter-free workspace. This will help reduce the risk of spills, which can be messy and pose a slipping hazard.

Next, if you choose to use baking soda and vinegar for your experiment, be aware that the vinegar reaction can sometimes be vigorous. So, it’s important to have a large enough container to prevent the mixture from spilling over the sides or place your glass on a tray to catch any spillage. 

While the ingredients used in either soda or the baking soda and vinegar version of the experiment are generally harmless, they can still cause mild irritation if they come in contact with your eyes or skin. To avoid this, you should wear safety goggles to protect your eyes and gloves to protect your hands.

During the experiment, it’s essential to handle the raisins with clean hands or a utensil. This prevents any contamination of the solution and ensures reliable results.

Lastly, when disposing of the solution after completing the experiment, remember that the raisins can clog the drain. Thoroughly strain the raisins from the liquid before discarding them in the trash. And as for the liquid, both soda and vinegar mixtures can be safely poured down the drain.

By following these safety precautions, you’ll be able to enjoy the dancing raisins experiment without any unnecessary mishaps. Have fun watching those raisins boogie!


How does this Science Experiment work?

The raisins will sink to the bottom of the glass when you first drop them into the soda. This is because they are more dense or heavier than soda. The carbonated beverage releases carbon dioxide bubbles that attach themselves to the wrinkly, rough surface of the raisin.

As the gas bubbles dissolve and dissipate, the raisins begin to rise. The raisins float to the top because the gas bubbles help increase the buoyancy of the raisins. The bubbles act like little tiny floatation devices for the raisin. LOL

Once the gas bubbles reach the surface of the glass, they pop, and the bubbles pop. This makes the raisin fall back to the bottom of the glass.

Is it a chemical reaction?

Yes, it is a chemical reaction. When you use baking soda and vinegar, they react to produce carbon dioxide gas. This gas forms bubbles, which cause the raisins to float and dance. In the case of carbonated beverages, the bubbles are already present in the drink, and no additional chemical reaction takes place.

What type of glass is best for this experiment?

A clear glass container will work best for this experiment so that you can get a great view from all sides and be able to see the dancing raisins clearly. I would also suggest a tall glass so that you can see how far up the bubbles can lift the raisins.

Why isn’t my dancing raisins experiment working?

If your raisins are not dancing, several factors may be affecting the experiment. First, make sure your raisins are fresh, as older raisins may not work as effectively.

Second, ensure you have used enough baking soda and vinegar (or carbonated beverage) to generate sufficient carbon dioxide bubbles.

Lastly, check if your raisins have any residue or oil that could prevent bubbles from forming on their surfaces.

Is this experiment related to osmosis?

The dancing raisin experiment is not directly related to osmosis, as it revolves around the behavior of gas bubbles, not the movement of water or any other solvent across a membrane.

Osmosis involves the passage of water molecules through a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration.

The dancing raisin experiment focuses on the buoyancy of raisins due to the attached carbon dioxide bubbles, which is a different phenomenon.
