These Candy Heart Science Experiments Will Blow Your Mind


Candy hearts aren’t just for sharing sweet sentiments during Valentine’s Day – they can also be the perfect medium for mind-blowing science experiments! In this article, we’ll delve into three fascinating candy heart science experiments that you can try at home to learn more about chemistry and physical reactions.

Experiment 1: Candy Heart Color Mixture

What you’ll need:

– Candy hearts in various colors

– Glasses of water

– A white plate or tray


1. Separate the candy hearts by color.

2. Fill glasses with water and place one candy heart of each color in separate glasses.

3. Observe how the color dissolves into the water.

4. Pour the colored water from each glass onto a white plate or tray.

5. Watch as the colors mix together and form new shades!

In this experiment, you’ll witness how different food colorings used in candy hearts can dissolve in water, showcasing principles of solubility and liquid mixing.

Experiment 2: Candy Heart Sink or Float

What you’ll need:

– A pack of candy hearts

– A jar or bowl filled with water


1. Fill a jar or bowl with water.

2. Predict whether candy hearts will sink or float when placed in the water.

3. Drop one candy heart into the jar or bowl and observe if it sinks or floats.

4. Add more candy hearts, one at a time, to see if the results change.

This experiment demonstrates buoyancy principles, as well as helps kids sharpen their observational skills and develop hypotheses about why certain objects sink while others float.

Experiment 3: Dancing Candy Hearts

What you’ll need:

– A pack of candy hearts

– Vinegar (white or apple cider)

– Baking soda

– A glass jar or cup


1. Fill a jar or cup with vinegar.

2. Add a few candy hearts to the jar or cup.

3. In a separate container, mix 1 tablespoon of baking soda with water (enough to dissolve the baking soda).

4. Pour the baking soda solution into the jar or cup and watch as the candy hearts begin to dance!

This experiment demonstrates the production of carbon dioxide gas (CO2) when an acid (vinegar) reacts with a base (baking soda), causing bubbles to lift the candy hearts in a fun, fizzy display.


Candy heart science experiments not only provide entertainment but also give kids and adults a hands-on approach to understanding fundamental scientific concepts. Try these experiments at home or in class for an enjoyable learning experience that promises to captivate and educate minds of all ages.
