Setting Up Your Dancing Raisins Experiment
This experiment is quick to set up and requires just a few items you likely already have at home.
Supplies You’ll Need:
- Clear Carbonated Soda: Club soda, 7-Up, Sprite, or any other clear, fizzy soda will work. An unopened bottle or can is ideal to ensure maximum fizziness.
- Raisins: Fresh raisins tend to work best.
Pro-Tip: Before you begin, gently separate any raisins that are clumped together. Individual raisins dance more effectively. Medium to small-sized raisins are also recommended for optimal dancing action.
Let’s Get Dancing: Step-by-Step Instructions
- Pour the Soda: Fill a clear glass with your chosen clear soda. Leave a little space at the top.
- Add the Raisins: Carefully drop a handful of raisins into the glass of soda. Before they start dancing, take a moment to observe what happens initially. Do they sink or float?
- Observe the Dance: Now, be patient and watch closely. It might take a minute or two for the dancing to begin. Get ready to witness the raisin dance!
The moment the raisins start to move is always a highlight for kids! They are usually thrilled to see the raisins rising and falling in the soda, creating a mesmerizing “dance.” Observing the bubbles clinging to the raisins and lifting them upwards is a truly cool sight.

The Science Behind the Dance: Why Do Raisins Dance?
Want to know the secret behind the dancing raisins? It’s all about science! Let’s break down the scientific principles at play in this fun experiment.
When you first drop the raisins into the soda, they sink to the bottom. This is because raisins are denser than the soda. Density refers to how much mass is packed into a certain volume. Raisins are more compact and heavier for their size compared to the soda, causing them to sink.
However, the magic of the “dance” begins with the carbonation in the soda. Carbonated sodas are infused with carbon dioxide gas. When you pour soda into a glass, or drop raisins into it, these dissolved carbon dioxide molecules start to form bubbles.
These carbon dioxide bubbles are attracted to the rough surface of the raisins. Think of the tiny bumps and wrinkles on a raisin – these provide perfect spots for bubbles to cling to. As more and more bubbles attach to a raisin, they collectively create buoyancy.
Buoyancy Explained: Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. In simpler terms, it’s what makes things float. As the carbon dioxide bubbles accumulate on the raisin, the overall buoyancy of the raisin increases. Eventually, the buoyant force becomes strong enough to overcome the raisin’s weight, and the raisin rises to the surface!
Once the raisin, along with its bubble entourage, reaches the surface of the soda, something else happens. The bubbles, now exposed to the air, pop! When the bubbles pop, the carbon dioxide gas is released, and the raisin loses its added buoyancy. Without the lift from the bubbles, gravity takes over, and the raisin sinks back down to the bottom of the glass.
This process repeats as more carbon dioxide bubbles form and attach to the raisins. The raisins continue to rise and fall, creating the captivating “dancing” effect. This cycle continues until the soda loses most of its carbonation and becomes “flat,” meaning there isn’t enough carbon dioxide left to create bubbles and lift the raisins.

Extend the Fun and Learning
The dancing raisins experiment is a great starting point for further scientific exploration. Here are some ideas to extend the learning and keep the fun going:
Experiment with Different Sodas: Try repeating the experiment with various types of clear sodas. Do they all work equally well? Does one soda make the raisins dance more vigorously than another? Observe and compare the results. This can lead to discussions about different levels of carbonation in various drinks.
Test Other Objects: Instead of raisins, try using other small, dense objects. Some suggestions include:
- Small pieces of uncooked pasta (like ditalini or small shells)
- Corn kernels
- Lentils
- Rice (While white rice might not work as well, you could try brown rice)
Predict which objects you think will dance and which won’t. Observe the results and discuss why some objects dance while others don’t. This can lead to a deeper understanding of surface texture and how it affects bubble attachment.
