The Magical Growing Sugar Snake!
Description:
Ever wondered if you could make a snake from sugar? In this fun and exciting science experiment, we’ll create a “magical” growing snake from sugar and baking soda! As we watch the snake grow, we’ll be learning some fantastic scientific principles too!
Scientific Principles:
- Chemical Reactions: This experiment will show how two substances (sugar and baking soda) can interact to create an entirely new substance. That’s called a chemical reaction!
- Combustion: We’ll learn about combustion, which is a type of chemical reaction that happens when something burns. In this case, the sugar will burn, which helps our snake to grow.
- Expansion of gases: The snake grows because of the gas produced during the reaction. This is a great way to visually understand how gases take up space.

Materials Needed:
- Baking Soda
- Granulated Sugar
- Sand
- Alcohol (or lighter fluid)
- A heatproof dish or plate
- A lighter or matches (ask an adult for help with this part!)
Difficulty Rating:
Obtaining the equipment: 2/5 (These items are common in most homes or can be found at a local store.)
Completing the experiment: 4/5 (With an adult’s help, it’s quite easy, but safety is crucial, especially when dealing with fire.)
Important Note! Safety is a top priority! Be sure to have an adult supervising at all times during this experiment. Don’t touch the “snake” until it has completely cooled down, as it will be very hot after the experiment. Also, only perform this experiment in a well-ventilated area, preferably outdoors.
Steps:
- Get Help From an Adult: Make sure you have an adult nearby to help you. Safety is really important in this experiment.
- Mix the Sand and Alcohol: Pour the sand into the heatproof dish or plate, spread it out to cover the bottom, and then pour the alcohol (or lighter fluid) on top of the sand.
- Mix the Sugar and Baking Soda: In a separate bowl, mix together the baking soda and sugar. Stir them until they’re really well combined. The mixture should look like fluffy, white snow.
- Make a Sugar Snake Nest: Scoop out a small hollow in the center of the sand. It’s like you’re making a little nest for your sugar snake. Then, pour your sugar and baking soda mixture into the hollow you just made in the sand.
- Light it Up (With Adult Help!): Now, ask the adult helping you to use a lighter or matches to set the sugar and baking soda mixture on fire. Remember to stand back and never lean over the experiment.
- Watch Your Sugar Snake Grow: Watch as the heat from the fire causes the sugar and baking soda mixture to puff up and grow into a black snake!
- Let it Cool: After the snake has finished growing and the fire is completely out, let the snake cool down for a bit. It’s going to be really hot, and touching it too soon could burn you.
- Inspect Your Snake: Once the snake has cooled down, you can touch it! See what it feels like and talk about what you see. Remember, the snake is fragile, so handle it gently.
And there you have it! You’ve just made your very own Magical Growing Sugar Snake. Remember, safety first and always have fun while learning!
Note: As this experiment involves fire and can produce smoke, please perform it outside or in a well-ventilated area.
Simple Explanation:
In our Magical Growing Sugar Snake experiment, we’re seeing some very cool science happen! When we light the sugar and baking soda on fire, it’s a bit like when you cook marshmallows. The heat makes the sugar burn and turn black, and it makes the baking soda get all puffy. Together, they puff up and grow into what looks like a snake!

Detailed Explanation:
In this experiment, a few different scientific processes are happening:
- Combustion: When we light the sugar on fire, it undergoes a process called combustion. Combustion is a chemical reaction that happens when something (in this case, sugar) reacts with oxygen in the air to produce heat and light. This process turns the sugar into a black material called carbon.
- Decomposition: At the same time, the heat from the fire causes the baking soda (which is sodium bicarbonate) to decompose. Decomposition is a chemical reaction where one substance breaks down into two or more other substances. The baking soda breaks down into three things: water vapor, carbon dioxide gas, and a new substance called sodium carbonate.
- Expansion of Gases: As the carbon dioxide gas is produced, it gets trapped in the hot, soft sugar. As the gas expands (because gases take up more space when they’re heated), it pushes the sugar outwards, making it grow and puff up into the shape of a snake.
So, what we’re seeing when our sugar snake grows is actually a combination of chemical reactions happening at the same time. It’s a visual representation of the process of combustion, decomposition, and the expansion of gases, all in one fun and exciting experiment!
