• It’s budget-friendly and easy to prepare
• It teaches chemistry without needing a full lab
• It makes abstract concepts visible and fun
• It inspires children to keep asking “Why?”

Before diving into the details, let’s meet five sweet science stars that are making science education deliciously exciting.

Meet the Stars: 5 Japanese Candies That Teach Science

Before we dive deep into each candy experiment, here’s a quick look at the five treats turning snack time into science time. Each one highlights a different chemistry or physics principle—and brings big smiles along the way.

Candy #1: Pachi Pachi Panic – Fizzy, Popping Pressure!

Pachi Pachi Panic Candy might look like a colorful sweet, but it packs a serious scientific punch. When you pour it into your mouth, it crackles and pops with a burst of sound and sensation. But what makes it fizz like that?

The answer is trapped carbon dioxide gas. During production, the candy is made by mixing sugar with CO₂ gas under high pressure. As the mixture cools and hardens, the gas is sealed inside tiny pockets. When the candy hits your tongue, it dissolves just enough to release the gas in a series of tiny, satisfying explosions!

What Kids Can Learn

• How gases expand and escape when pressure is released
• The difference between physical and chemical changes
• How temperature and moisture affect reactions

This treat is a great conversation starter for topics like the gas laws, carbonated drinks, or even how airbags work!

Try This at Home or in Class

• Drop the candy into cups of warm and cold water—what’s the difference?
• Use a smartphone app to measure how loud the popping is
• Time how long the popping lasts and compare with friends

Because this candy is edible, safe, and doesn’t require heat or tools, it’s perfect for science fairs, STEM stations, or rainy-day activities at home. And let’s face it—kids love snacks that make noise!

Candy #2: Neru Neru Nerune – Colorful Reactions in a Cup

Neru Neru Nerune isn’t just a snack—it’s a hands-on chemistry set in candy form. Kids mix colored powders with water in a tray, and watch the mixture bubble, foam, and change colors right before their eyes. The transformation feels magical—but it’s all science.

The key reaction is between an acid (often citric acid) and a base (like sodium bicarbonate). When combined with water, they react to produce carbon dioxide gas, which creates foam. Some versions of Neru Neru even include pH-sensitive ingredients that shift color depending on acidity—just like litmus paper!

Science Topics You Can Explore

• Acid-base reactions and neutralization
• Why bubbles form (gas release)
• How color indicators work with pH

This is a perfect introduction to chemical reactions—especially for younger learners. They get to be scientists and chefs at the same time.

Simple Experiments with Neru Neru

• Test warm vs. cold water to see how temperature affects foaming
• Time how long the foam lasts and chart results
• Have kids predict the color changes before mixing

Everything happens in a small, safe tray—no mess, no fire, no sharp tools. That makes it perfect for classrooms and at-home learning alike.

Candy #3: Fue Ramune – Whistle While You Learn

Fue Ramune is more than just a candy—it’s a musical instrument you can eat. Each piece is shaped with a central hole. When you blow into it, it makes a loud, high-pitched whistle that surprises and delights. Kids love it for the fun; teachers love it for the physics.

This candy demonstrates the science of sound. When air is blown through the hole, it vibrates inside the cavity, creating sound waves. This is the same principle behind wind instruments like flutes and whistles.

Physics Topics to Explore

• Airflow and vibration
• Pitch and frequency
• How sound travels through air

Each whistle is slightly different, depending on how hard you blow or the angle of airflow. This leads to great experimentation with tone and volume!

Try This in the Classroom

• Use a decibel app to measure sound levels
• See how pitch changes with gentle vs. strong blowing
• Record the sound and compare with a real flute or whistle

After the sound experiments are done, kids can enjoy the ramune flavor—a fizzy soda-inspired treat. It’s a sweet reward for a job well learned!

Candy #4: Purunto Konjac Jelly – Stretch, Squish, and Learn

Purunto Konjac Jelly is a soft, squeezable jelly snack made from konjac root—an Asian plant known for its fibrous, gelatinous texture. Unlike regular gelatin snacks, konjac jelly has a firmer consistency that stretches, bounces, and returns to shape. That makes it ideal for exploring the science of gels and materials.

This jelly showcases the fun behavior of non-Newtonian fluids—acting like a solid when squeezed quickly and smoothly shifting when pressed gently. It invites playful exploration with every squish!

Science Topics to Explore

• Gel formation and elasticity
• Viscosity and resistance
• How pressure changes material behavior

This activity is all about texture, and how matter can exist in more than one state at once. It’s a great way to introduce states of matter beyond the traditional solid-liquid-gas model.

Classroom or Home Experiments

• Refrigerate vs. room temperature jelly—how does texture change?
• Drop test! Measure bounce height from different heights
• Try stretching and timing how long before it breaks

These simple activities give kids a hands-on way to observe elasticity and discuss real-world applications like medical gels, contact lenses, or even space food!

Candy #5: Gumi Tsureta – Reel In Real-Time Chemistry

Gumi Tsureta is an interactive candy kit that lets kids create long, stretchy gummy “worms” using a simple dipping process. But beneath the fun lies a fascinating science experiment in polymer chemistry.

The kit usually contains two solutions: one is a sugary syrup, and the other is a gelling agent (often containing alginate). When a string or hook is dipped into the mixture, polymers begin to form around it, creating gummy strands that you can literally fish out of the liquid. It’s a hands-on demo of how molecular chains come together to form something new!

Science Topics to Explore

• Monomers and polymerization
• Gel formation and reaction timing
• Differences between physical and chemical changes

This activity offers a perfect example of real-time polymer science. It’s great for introducing kids to molecular structures or even drawing comparisons to DNA or slime-making.

Try These Learning Challenges

• Time how long it takes to form a gummy strand
• Predict how gummy length changes if you dip for 5 vs. 10 seconds
• Have kids try shaping letters or spirals with the fishing rod

Each attempt is a new trial, encouraging experimentation and refinement—key aspects of the scientific method. It also makes for an exciting, collaborative classroom challenge.
