Fizzing, bubbling, slime making for Valentine’s Day reminds me of fun potions! This is a great combination of all things chemistry with slime making and a fizzy chemical reaction. How do you make slime bubble and fizz? This is by far one of the coolest bubbly slime recipes we have to date because it combines two things we love: slime making and baking soda vinegar reactions.
VALENTINE’S DAY BUBBLY SLIME RECIPE
This is slime making taken to a whole new level of slimy goodness perfect for Valentine’s Day science with love potions and chemical reactions.
How do you make slime with baking soda and vinegar?
Generally, we think of crazy chemical reactions when we mix baking soda and vinegar and the classic volcano science project! Well, we took it one step further and can show you how to make slime that fizzes and bubbles.
This bubbly slime recipe has the definite oooh and aaah factor, but is also super easy to set up. A little messy, this bubbling slime is going to be a big HIT.
Plus you get a fun, stretchy slime out of the science experiment! We used our classic saline solution slime recipe with a bit of a twist…
BUBBLING SLIME BAKING SODA VINEGAR ACTIVITY
Honestly, what’s not to LOVE about this bubbling slime volcano, and I love how easy you can change up these types of recipes for the holidays and seasons…
Valentine’s Day is the perfect opportunity to make things that fizz and bubble and erupt!
The recipe instructions and mixing are different than all our other slimes, so I recommend you read through the directions, tips, and tricks before you get started. As always the right slime ingredients paired with the BEST slime recipes is key!
Note: The slime that is produced is fun and stretchy but definitely is not as high quality as our original slime recipe. Of course, making a lava slime volcano is half the fun. If you want a super awesome stretchy slime without a volcano, check out the original saline slime recipe here.
We always like to include a bit of homemade slime science around here. Slime really does make for an excellent chemistry demonstration and kids love it too! Mixtures, substances, polymers, cross-linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored with homemade slime!
What’s the science behind the slime? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl acetate) glue and forms this cool stretchy substance. This is called cross-linking!
The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until…
When you add the borate ions to the mixture, it starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime! Slime is a polymer.
Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms, the tangled molecule strands are much like the clump of spaghetti!
Is slime a liquid or solid? We call it a Non-newtonian fluid because it’s a little bit of both!
SLIME FOR NGSS: Did you know that slime aligns with the Next Generation Science Standards? It does and you can use slime making to explore states of matter and its interactions. Check out NGSS 2-PS1-1 for more information!
Of course, there is an additional science experiment going on here which is the chemical reaction between the baking soda and the vinegar. When the acid and base mix together, they produce a gas called carbon dioxide. This is seen in the fizzing bubbling eruption that takes place when you stir the slime! Continue to explore states of matter too!
BUBBLY SLIME INGREDIENTS
Read more about our RECOMMENDED SLIME INGREDIENTS here. Learn how to make slime with baking soda, vinegar, and glue for the ultimate slime making experience!
- 1/2 cup Elmer’s Washable White School Glue
- 1 tbs Saline Solution
- 2 tbs Baking Soda
- 1/4 cup White Vinegar
- Food Coloring (red, pink or purple)
- Heart Confetti (optional)
- Small Container (for mixing slime volcano)
- Small Cup (for mixing vinegar and saline solution)
- Cookie or Craft Tray
SLIME TIP #1:
When looking for a good container for your bubbly slime, find something that is on the taller side but with a wide enough opening to allow you to easily mix the slime as well. The nature of a baking soda and vinegar volcano is that the gas produced during the reaction pushes up and out.
A taller and narrower container will yield a better eruption compared to a wider and shorter container. We like our inexpensive beaker set for fun science activities.
BUBBLING SLIME INSTRUCTIONS
STEP 1: Start by combining the glue and baking soda in your chosen container. You will notice that as you stir the baking soda into the glue it thickens! This is really the point of adding baking soda to saline solution slime recipes.
SLIME TIP #2: Experiment with different amounts of baking soda!
STEP 2: For bubbly slime love potion we used red and purple food coloring, but we didn’t mix them together straight away. Add 5 red drops to the glue and baking soda mixture and stir.
Then add 1-2 drops of purple food coloring but DO NOT stir! This will give way to a fun color burst as you mix. You can really make this bubbly slime volcano any color you want! Top with confetti hearts too!
Step 3: In another small container, mix the vinegar and the saline solution.
SLIME TIP #3: You can also play around with the amount of vinegar you use for another way to set up a slime experiment!
Step 4: Pour vinegar/saline mixture into the glue mixture and start stirring!
You will notice the mixture begin to bubble and eventually erupt everywhere! This is the reason for the tray!
Step 5: Continue to stir until the eruption is complete. You will notice that it gets harder and harder to stir because you are mixing your slime as well!
Once you have stirred as much as possible, reach in and pull out your slime! It will be a bit messy at first but this slime is wonderful! All you need to do is knead it a bit.
SLIME TIP #4: add a few drops of saline to your hands before you reach in for the slime!
It should not be sticky on the hands either! But if after kneading your slime it still feels sticky, you can add a drop or two of saline to it and continue to knead. Don’t add too much or you will end up with a rubbery slime!
Go ahead and play with your volcano slime!
What can you do with the leftover slimy eruption on the cookie sheet? You can actually play with it too! We added a squirt of saline to it and had some fun messy slime play. It makes a great popping sound when you squeeze it due to all the bubbles from the reaction that are left over!
As I mentioned above, the slime that is created along with the fizzing slime volcano is not necessarily something that will save for weeks. We found it got a bit watery and not as nice the next day.
The whole slime volcano activity itself is AMAZING!
It’s a MUST try for the slime making and science experiment to-do list.
