What is the science behind Pop Rocks?

What is the science behind Pop Rocks?

The secret behind that famous Pop Rocks candy “popping” sensation is pressurized carbon dioxide gas (CO2). Each of those tiny little candy pebbles contain a small amount of the gas. When they burst free from their candy shells, these tiny gas bubbles make that irresistible popping sound.

What is the chemical reaction between Pop Rocks and soda?

In chemistry, we call the reaction between the Pop Rocks and soda a physical reaction. The two substances have a mechanical interaction that allows for the release of carbon dioxide. The liquid in the soda dissolves the candy, allowing for carbon dioxide to escape and trigger more bubble formation in the soda.

What causes Pop Rocks and soda to inflate a balloon?

Pop Rocks candy is pressurized carbon dioxide gas. The soda will cause this because it is pressurized carbon dioxide gas. Once you have dropped the candy into the soda, the carbon dioxide gas will cause the balloon to inflate because it has nowhere to go in the bottle.

Why do Pop Rocks work?

Small candy pieces encapsulating bubbles of high-pressure CO2. Lo, the magic of carbonation! When you eat Pop Rocks, the moisture and temperature in your mouth melts the candy. The subsequent popping sounds are a result of the high-pressure CO2 bubbles being released into atmospheric pressure!

How do you make Pop Rocks explode?

When the candy is hot and being formed at the factory, carbon dioxide gas is added to the sugary mixture under extreme pressure. When you eat the candy, it melts in your mouth, releasing the pockets of pressurized carbon dioxide, causing that exploding sensation Pop Rocks are known for.

Are Pop Rocks a chemical or physical change?

It is a chemical change, or reaction. Pop Rocks® do not contain sodium bicarbonate or either of the acids found in the other candies. The pop that results is caused by the release of carbon dioxide bubbles that are encapsulated within the candy.

Why do nerds react with soda?

Once you open your box of Nerds you will see that they are colorful little crunchy sour candies. Since they are sour they will produce acid. This acid is what will form more bubbles in the soda making your balloon blow up faster and bigger!

Why does the pop rock candy react on the soda?

A package of Pop Rocks contains less carbonation than half a can of soda. When the candy comes in contact with moisture, whether it be saliva, milk or Coca-Cola, the candy dissolves. The gas inside the carbon dioxide bubbles is released, which causes the fizzling sounds the candy is often associated with.

Why do pop rocks react with soda?

Mixing Pop Rocks with soda causes a physical reaction – not a chemical reaction. It is simple! The soda dissolves the candy and dropping Pop Rocks into soda causes the carbon dioxide which is already in the soda (that is what those fizzy bubbles in soda are made of) to release inside inflating the balloon!

Why do Pop Rocks explode when mixed with soda?

Soda contains dissolved carbon dioxide. Adding the pop rocks to the soda provides a surface for carbon dioxide bubbles to collect. The bubbles head to the surface and push their way out of the container causing the eruption. The addition of soap to the pop rocks volcano makes the eruption more frothy.

What really happens when you mix pop rocks and Coke?

Adding Pop Rocks to soda releases the trapped gas within the candy and also within the soda itself. Since the soda’s carbon dioxide is highly pressurized, it shoots out of the bottle since that’s the one place for the gas to go.

What is the science of Pop Rocks?

The Science Behind It. Pop rocks contain pressurized carbon dioxide covered with a candy coating. When the candy coating begins to dissolve, the carbon dioxide gas is released. (It breaks through the now thin candy shell.) That’s when you hear the popping sound. The candy coating dissolves in your mouth or in other liquids like water and soda.
