Dancing Candy Hearts

Around Valentine’s Day, my kids get lots of those candy conversation hearts.  I remember as a kid, I loved reading the messages on them.  The messages are a bit different these days (“Text me”?)  Save a few of those hearts to do this quick 5 minute science experiment.  Use up some candy, do a little science, watch a little dance.

Here’s what you’ll need to get started:

  • Candy Conversation Hearts
  • Tall clear glass (we used a tall glass and a test tube)
  • Baking Soda
  • Vinegar
  • Water
  • Measuring spoon


Add 1 cup of water to a clear tall glass or tall test tube.  You can color yours purple or red for Valentine’s Day but that is totally optional.


Add in 2 teaspoons of baking soda and mix well.


Add a few candy hearts to the glass.


We used one of each color.img_0620Watch the hearts sink to the bottom of the glass.

Add about 1/4 cup of vinegar to the glass slowly (or else it will will overflow!)


Watch the candy hearts dance… or in our case, only the pink and orange hearts danced.  The rest stayed happily at the bottom of the glass.img_0627

It really looked so cool watching the hearts float up and then sink down.

We will definitely be trying this again by testing the different colored hearts separately, testing different brands and testing different fizzy liquids to see if any of those change how the hearts behave.

The Science Behind the Activity:

This is a great experiment demonstrating sinking and floating.  The hearts are denser than the liquid so they initially sink when you put them in.  When the vinegar is added, the reaction creates carbon dioxide gas.  As the carbon dioxide gas bubbles attach to the surface of the hearts, they decrease the density of the hearts and the hearts float to the top.  At the surface of the liquid, the gas bubbles pop and the hearts sink back down.  The process keeps repeating until there isn’t enough carbon dioxide left to raise the hearts.

Inflating Spooky Ghost!

You have to try this super easy experiment that will WOW! your littlest ones.  Using my favorite 2 ingredients and a balloon, this one is great for Halloween parties or just for fun!

Here’s what you need to get started:

  • Baking Soda
  • Vinegar
  • Funnel
  • Empty water bottle
  • White balloon
  • Black sharpie


Inflate the balloon slightly and draw a ghost face with the sharpie

img_9084Here’s my attempt at a spooky face


Let the air out.  Place the funnel into the opening of the balloon and add about 1-2 tablespoons of baking soda into the balloon.


Place the balloon aside and add some vinegar to the empty water bottle

img_9088 img_9089

Place the balloon over the mouth of the water bottle taking care that none of the baking soda (the secret) drops into the vinegar below…yet.


Now, the fun begins!  Turn the balloon upside down so it dumps the baking soda into the bottle and watch!


The kiddos LOVED it!!!  Such an easy and simple little experiment to set up!

Science behind the Activity:

This is a twist on the classic baking soda and vinegar experiment.  Baking soda is a base and vinegar is an acid.  When combined, they release carbon dioxide gas (the bubbles).  Since the gas is trapped by the balloon, the balloon inflates and reveals the ghost!





Fizzing Jupiter

For those of you who follow my activities, you know how much I love my baking soda and vinegar experiments.  To be fair, the tots and my littlest superhero LOVE baking soda and vinegar so it’s not ALL about me 🙂

This one is a simple and easy addition to your space theme.  I call them Jupiters (even though my color mixing wasn’t as successful as Jupiter) but you could make them any planet or leave them white for the moon.

Here’s what you need to get started:

  • Baking Soda
  • Water
  • Measuring cup
  • Large Mixing Bowl
  • Tray for drying the rocks
  • Vinegar
  • Black or purple food coloring (optional – but colors make everything more fun!!)


To make the planet:

Combine 2 cups of baking soda and 1/2 cup of water (add the desired color to the water) in a large bowl.  To make the the Jupiters, I split this into two bowls, one with red (looked orange) and one with yellow.

img_8750 img_8751

Then I mixed both together to get an orange-yellow swirly Jupiter look.  Kind of.


Using your hands, take a handful and roll into a ball.  If it’s too dry, it won’t stay together, if it’s too watery, it will melt into a sloppy puddle.  Add water or more baking soda to adjust the consistency.  


Let them dry overnight.  I placed mine in a plastic container and put them in the freezer to harden. 

The next morning, the planets were hard.    Note: this recipe will yield about 10 balls.

To explore:

I gave each little one a “Jupiter” and a cup with vinegar that had black food coloring and some silver glitter (“Starry Space Juice” is what I called it!).


The tots definitely know what to do with the dropper and the vinegar.  Space juice was added to the planets for some fizzy fun!

Apple Volcano

This was our first full week of fall and it’s been HOT and sweltering over here.  Finally today, it feels like Fall and it’s a perfect day to celebrate apple season.  Aside from eating and baking apples, why not use some over-ripe apples to play with? Here’s an easy twist on the classic “volcano” experiment, just in time for Apple season.  So, while you are picking out your apples, get a few extra and let your little ones have some explosive fun!

Here’s what you need to get started:

  • Apples (any variety will do)
  • Baking soda
  • Vinegar
  • Food coloring/liquid water colors (optional – but everything is so much more fun with colors!)
  • Knife and metal spoon to hollow it out (Adult use only)
  • droppers and spoons
  • cups
  • Tray to contain the mess


First cut the top off the apple and scoop out the insides and the seeds to form a “bowl”.  I found it easiest to cut a circle off the top and then use a metal tablespoon to scoop it out.


This kept the top of the apple intact to use as a lid.  We saved the seeds and stem for our Exploring the Five Senses with Apples activity.


I set up a tray with the hollowed apple, dropper, cup of baking soda, spoon and cup of vinegar (I colored ours red for fun)


Then I invited the superheroes to play.  These little ones KNOW exactly what to do with baking soda and vinegar!


Repeat as many times as your superheroes want to do it.  We went through a box of baking soda between the two older ones!


The Science behind the activity:

This is a classic acid-base reaction.  Baking soda is a base and vinegar is an acid.  When they combine, they create a chemical reaction where the baking soda neutralizes the vinegar.  A by-product of the reaction is carbon dioxide.  That is what the bubbles are.  As the carbon dioxide is formed and bubbles out, it carries some liquid up with it, hence the “eruption”.


There are a million ways to do this experiment.  I can pretty much adapt this to any theme.  Another great Halloween theme application of this is the Pumpkin Volcano, which we also did.

For my Tiny Tot class, I ended the class by reading “Ten Apples On Top” by Dr. Seuss.

Fizzing Leprechaun Pots

Baking soda and Vinegar are my two most favorite science experiment ingredients! They are inexpensive, always in the pantry and there are just SO many fizzy, colorful things to do with them.  Here’s my latest version, just in time for St. Patrick’s Day but would also be so much fun as a witches’ brew at Halloween

Here’s what you need to get started:

  • Baking Soda
  • Vinegar
  • Food coloring (I love my liquid watercolors)
  • Candy Kettles (any party store has them seasonally)
  • Bin/tray for the mess
  • Glitter (I used gold and green for St. Patty’s Day)
  • Teats, gold coins, etc… to hide in the pots (not necessary)
  • Droppers
  • Cups for the vinegar

To set up:

I placed a few pots in the bin.  I placed one treasure (plastic gold coins) at the bottom and added 1-2 teaspoons of baking soda on top. I sprinkled a little glitter on top of baking soda because glitter is sparkly and so much fun!IMG_1148

Pour vinegar (Leprechaun Potion or Witch’s Potion) into small cups.  I used 6 different colors to create a rainbow.

IMG_1150 2

To play: 

I gave a small bin with a few pots inside to each of the tiny tots in my class.  I supplied them with a large dropper (more like a turkey baster-perfect for toddlers!)  And then the magic began!

IMG_1150They added their favorite colors to the pots and watched them bubble and fizz!  So easy!  So fun!  So colorful!


That’s IT!  See, you can do this at home too!  And the little ones love it!  Adapt it for Halloween by placing plastic eyeballs, spooky fingers, creepy spiders, etc… for a spooky witches’ brew!  Or use plastic easter egg halves like I did with my Fizzing Easter Eggs experiment.  Or place some baking soda in a hollowed out mini pumpkin and make Pumpkin Volcanoes or into apples for Apple Volcanoes!  So many options!

Rainbow Fizzing Tray

Baking Soda and Vinegar are by far the BEST two ingredients you can have on stock for setting up some fun science explorations.  This Rainbow Fizzing Tray is EASY set up and clean-up and can keep your little ones busy for quite a while.  The tots in my classes kept wanting to do this one OVER and OVER!  And an added benefit: it makes beautiful designs!  Science and Art all in one!

Here’s what you’ll need to get started:

  • Small tray/plate or cookie sheet
  • Baking Soda
  • Vinegar
  • Food coloring (We use liquid watercolors)
  • Droppers
  • 3-6 empty cups (or an ice cube tray)


Add enough baking soda to your tray to cover the bottom.


Pour vinegar in your cups and add food coloring to create your desired colors.  We used the six rainbow colors but even just the 3 primary colors will yield some beautiful results and can be a lesson on color mixing.  You can also use an ice cube tray.


Hand your child the tray and a dropper and let them add the colors to the tray and experience the fun rainbow fizzing and eruptions!


Drips and fizzing and bubbles and colors!

Version 2

Perfect for toddlers as well as preschoolers.

How pretty are some of the designs the tots created?

The Science Behind the Activity:

I love activities like this because they are open ended and require no instructions for kids.  The baking soda and vinegar react in a classic acid/base reaction to release carbon dioxide gas which is responsible for the fun eruptions and bubbles.  Using droppers helps strengthen those little fingers in preparation for writing as well as developing fine motor skills.  Mixing different colors is a lesson in color mixing and experimentation.  Just SO MUCH learning to be had from a simple little tray.

Love Potions

Did your kids get way too many candies for Valentine’s Day?  Why not use some of it up with some Love powder and Love juice to make some “Love Potions”?  So easy to set up and a great way to use up that candy!

Here is what you need to get started:

  • leftover candy (we used skittles, nerds and conversations hearts, but you can use whatever you have!)
  • cups or beakers or large plastic test tubes
  • droppers
  • spoons
  • Love Powder (baking soda-I tinted mine pink)
  • Love Juice (vinegar-I tinted mine purple and red)
  • water

To make the love powder, I just placed some baking soda in a ziplock bag and added some red food coloring to it and mixed it well.  Plain white baking soda works just fine!  For the Love juice, I added red and purple food coloring to plain white vinegar.  I love colors.  So do the kids!

I placed the test tubes in a bin to contain the mess.  I gave each child an empty cup, a cup of love powder and some love juice, a dropper and cup filled with assorted colorful candies.
IMG_5148 And I let them mix and make their potions!


They love using droppers to make precise measurements and the addition of some vinegar and baking soda to make bubbly potions!


Pouring from the cup works just as well too!


And for a bonus, some of the conversation hearts began “dancing” in the bubbly potions!  (This is actually another simple candy experiment that you can do at home as well!  For more details, visit my Dancing Candy Hearts experiment)



All in all, the tots had a blast mixing and pouring and fizzing and bubbling, and we used up a lot of leftover candy experimenting instead of getting cavities:)

Science Behind the Activity:

This is one of my favorite activities because it allows young children to be creative and explore and investigate.  I didn’t give them any instructions, just some materials and let them have at it.  One of the girls just wanted to make things fizz.  Another child wanted to see what colors the potions would turn with different candies.  One just wanted to mix everything together.  Each child did something different.  And most importantly, they learned about cause and effect: What happens if I do this?
