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.

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. Need more proof?

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!

What ingredient makes Pop Rocks Pop?

To make Pop Rocks, the hot sugar mixture is allowed to mix with carbon dioxide gas at about 600 pounds per square inch (psi). The carbon dioxide gas forms tiny, 600-psi bubbles in the candy.

How do you do the pop rocks and soda experiment?


  1. First, fill your balloon with one bag of Pop Rocks using the funnel. You don’t want the Pop Rocks to come in contact with the soda until you’re ready to blow up the balloon.
  2. Next, open your soda and attach the balloon to the top.
  3. Shake the Pop Rocks into the soda and watch your balloon inflate.

Can my dog eat Pop Rocks?

In addition to these dangerous candy additions, plain rock candy or lollipops can pose a choking threat if swallowed whole. (They’re also not great for your dog’s teeth.)

Do they make Pop Rocks anymore?

Back in 1956, food chemist, William A Mitchell invented Pop Rocks for General Foods, while trying to make an instant soft drink. After all the hassle of convincing people they were not dangerous, Pop Rocks were discontinued in the mid-1980s, but have since been resurrected.

What happens if you mix Pop Rocks and water?

When you crush or dissolve the Pop Rocks (in your mouth, by grinding, or by dissolving in soda or water), you release the carbon dioxide (that’s what makes the popping sound in your mouth). When you mix Pop Rocks with soda, the carbon dioxide in both the soda and the Pop Rocks is released.

What triggers Pop Rocks?

Tiny CO2 bubbles become trapped in the mixture, which makes the candy shatter when it hardens and the pressure is released. The release of trapped carbon dioxide trapped in the Pop Rocks is ultimately what causes them to pop and fizz when they’re exposed to the heat and moisture in your mouth.

What do you need for a pop rock science experiment?

All you need for this pop rocks and soda experiment are 1 liter bottles of soda (we like to try various different ypes of pop such as mountain dew, coca cola, pepsi, sprite, root beer, dr pepper, etc.), balloons, and pop rocks. This balloon science experiment only takes 5 minutes and is virtually mess free!

How to make Pop Rocks Fizz and bubble?

STEP 1. To make baking soda dough, mix baking soda with a small amount of water until a packable dough begins to form. Do not make it too wet! Use vinegar to make it fizz and bubble with pop rocks. Check out our favorite fizzing science experiments!

What’s the difference between Soda and Pop Rocks?

Make sure you use a fresh bottle of soda. If the soda has been opened before, the carbon dioxide will escape and your balloon won’t inflate. If you’re still not getting a big balloon, make sure all the Pop Rocks get out of the balloon and into the soda.

How do you make a Pop Rocks expander?

Place the narrow end of the funnel into the mouth of the balloon. Empty the Pop Rocks packet into the funnel. Make sure the funnel is empty by giving it a few firm taps. You should be able to see into the balloon. Place the opening of the balloon over the mouth of a bottle of soda. The balloon should hang down beside the bottle.
