Have you ever tried Pop Rocks candy? If you haven’t had them before, they are an awesome experience for everyone. Every kid should try eating some Pop Rocks at least once! A fun candy to eat, and now you can turn it into an easy Pop Rocks science experiment too! Find out what happens when you mix soda with pop rocks! Can you inflate the balloon? Take the Pop Rocks and soda challenge with this cool chemistry experiment.

POP ROCKS AND SODA CHALLENGE

POP ROCKS AND SODA

Our Pop Rocks and soda experiment is a fun variation on our baking soda and vinegar reaction. We love fizzing experiments and have been exploring chemistry for kindergarten, preschool, and early elementary for almost 8 years. Make sure to check out our collection of simple science experiments for kids.

Our science experiments are designed with you, the parent or teacher, in mind!  Easy to set up, quick to do, most activities will take only 15 to 30 minutes to complete and are heaps of fun!  Plus, our supplies lists usually contain only free or cheap materials you can source from home!

Grab a packet of Pop Rocks and some soda and find out what happens when you mix them together!

POP ROCKS AND SODA EXPERIMENT

MATERIALS NEEDED:

  • 3 bags Pop Rocks Candy Variety Pack 
  • 3 (16.9 to 20-ounce bottles) soda in different varieties
  • Balloons
  • Funnel

HOW TO SET UP POP ROCKS EXPERIMENT

STEP 1. Stretch the balloon with your hands, making an effort to expand the neck of the balloon. Avoid blowing into the balloon as the moisture from your mouth will make the candy stick to the inside of the balloon later on.

STEP 2. Place the mouth of the balloon over the small opening of a funnel. Then pour one package of Pop Rocks into the funnel and tap the funnel to force the Pop Rocks down into the balloon.

TIP: If the candy refuses to move through the funnel, try pushing the candy with a bamboo skewer without putting a hole in the balloon.

STEP 3. Open the soda and place the opening of the balloon over the top, taking care to have the mouth of the balloon completely over the top of the bottle without dropping the candy into the balloon.

STEP 4. Tip the balloon up and shake slightly (if needed) to transfer the candy into the soda.  Watch what happens to the soda and the balloon!

TIP: Make sure to use a level surface so the bottles do not fall over.

Usually, gas will begin to form immediately. Expect the soda to get fizzy, the candy to crackle, and the balloons to fill with air and foam.

If a balloon fails to expand, examine the experiment to see what happened. Typically this will happen if the balloon is not completely over the top of the soda bottle.

BONUS POP ROCKS EXPERIMENTS

Here are several ways you can use the scientific method by:

  1. Using one variety of soda and testing the different varieties of Pop Rocks to see if each has a similar reaction. Measure the balloons to decide which variety created the most gas.
  2. Using the same variety of Pop Rocks and testing different varieties of soda to see which emits the most gas. (We found Diet Coke tends to win!)

Make sure to save some Pop Rocks for another fun Pop Rocks experiment exploring viscosity.  Test whether Pop Rocks are louder when placed in liquids of different viscosity or thickness.  Click here for our viscosity Pop Rocks Experiment!

WHAT HAPPENS WHEN YOU MIX POP ROCKS AND SODA

Why do Pop Rocks pop in your mouth? As Pop Rocks dissolve they release a very small amount of pressurized gas called carbon dioxide which makes the popping noise! You can read more about the patented process of Pop Rocks.  However by themselves this is not enough gas to inflate a balloon. That’s where the soda helps!

The soda is a carbonated liquid so it contains lots of pressurized carbon dioxide gas. When the Pop Rocks are dropped into the soda, some of the gas in the soda collects as bubbles on the candy. Some of this gas then escapes from the water and the corn syrup that holds it and moves upwards. The gas fills the space at the top of the bottle and then moves up into the balloon.  The balloon is inflated as the volume of carbon dioxide gas increases.
