Bubbling Fizzy Cauldron STEM

*RED Bubbling Fizzy Cauldron STEM Kids Science Experiment

Bubbling fizzy color-mixing cauldron acid-base science experiment to promote STEM education in toddlers, preschoolers, and kindergartners.

Whether we are looking for a Leprechaun’s pot of gold at the end of the rainbow or brewing a colorful potion, make this Bubbling Fizzy Cauldron STEM experiment with a few simple household ingredients! Besides, by skipping dish soap, this science experiment is safe for babies and toddlers who are still mouthing objects! Most importantly, this kid-safe TASTE-SAFE color-mixing activity is perfect for all ages and will expose little scientists to the most satisfying-to-watch ACID-BASE reaction.

TASTE-SAFE Color-Mixing Science Experiment INSTRUCTIONS

First, set up your waterproof tray to catch the spillover. (Grass filler is optional.) Secondly, arrange cauldrons and add a heaping amount of baking soda to each. Next, add the desired food coloring to each cauldron’s baking soda. Next, MIX baking soda and food coloring. (You want the food-coloring to ‘coat’ and mix with baking soda so that the eruption is colorful. If you do not mix it, the vinegar might activate with baking soda that has not been ‘colored’ and you will have a colorless eruption.) Lastly, pour vinegar over the baking soda cauldron, and watch the bubbling fizz erupt! REPEAT!

SUBSTITUTE: Instead of vinegar, you can use lemon/ lime juice/concentrate or freshly squeezed citrus.

TASTE-SAFE STEM

This bubbling fizzy cauldron STEM experiment is TASTE-SAFE for littles ones who are still mouthing things since you are using basking soda and food coloring! However, taste-safe does NOT mean edible!

Please note, you can add a squirt of dish soap, however, your experiment will NO LONGER be TASTE-SAFE!

We still want to DETER little ones from eating anything that is NOT food! Good habits will ensure SAFE play! So, if they put it into their mouth, calmly say โ€œNo, not for eating. Not in your mouth.โ€ or โ€œDo not put it in your mouth. This is not food.โ€ Or stick a tongue out and make a yucky /disgusted face. Most importantly, model appropriate ways to play. If the behavior persists, remove and introduce it later.

The BEST part of this experiment is that you can conduct it MULTIPLE TIMES! Since when you pour vinegar over the baking soda, the vinegar will ONLT activate the top layer of it, leaving the bottom layer intact. So, try after your FIRST eruption, adding MORE VINEGAR and watch it FIZZ AGAIN! If you pour the vinegar and nothing happens, ADD MORE BAKING SODA! AND REPEAT!

Whatโ€™s the science behind Bubbling Fizzy Cauldron STEM?

Itโ€™s chemistry! It’s an ACID-BASE reaction! This TASTE-SAFE Color-Mixing Science Experiment is SIMPLE. It’s FUN! And it never ceases to amaze little people!

When baking soda (a base) and vinegar (an acid) are mixed together, they react with each other because of an atom exchange. (Baking soda receives a proton from vinegar). And one of the products this reaction creates is carbonic acid which is very unstable. Thus, carbonic acid instantly breaking apart into water and carbon dioxide molecule. And since the carbon dioxide molecule is now free of its other chemical bonds, it can escape, bubbling forth as a gas. As a result, this chemical reaction releases gas which bubbles and fizzes, making it a fun sensory acid-base kids experiment. The food coloring helps you see the bubbles a little better.

So, in the nutshel, it is the CO2 gas that is responsible for all the fizzing as the gas escapes the solution!

PLEASE, ALWAYS SUPERVISE YOUR CHILD!

A few discussion questions you can ask your kids to think about with Bubbling Fizzy Cauldron STEM:
  • What would happen if you would add coloring to vinegar instead of baking soda? (Hint: Same result, but you can skip mixing baking soda with coloring.)
  • What if we changed how we added the ingredients together? For example, if we poured the baking soda into the vinegar instead of the other way around? (Hint: Same result, since it the MIXING of ingredients that matters and not the order).
  • Can this potion be used for anything? (Hint: Baking soda and vinegar makes a great household cleaner!)
