Fizz, Bubble & Pop! Experimenting with Vinegar + Baking Soda

Pin It
Simply put,
Vinegar + Baking Soda & Food Color = Science FUN!

I hadn't taken the time to do this with the Lil Divas &
I have been meaning to do it with them for over a year.

Mad Science Week is the perfect time for fizzy, popping, messy experiments!

This is an easy, fun & inepensive experiment that will delight your little ones!
The Lil Divas kept doing it over & over - never tiring of the results.

Experimenting With Baking Soda & Vinegar

What You Need:
baking soda
clear cups or containers
the clear cups were fun to use but you can use whatever you have on hand - even muffin tins
food coloring - optional
*I recommend a tray to hold any spills - it helps minimize the mess!*

What To Do:
1. I added a few drops of food color to each spoon for a fun effect - it was definitely more visual
and the Lil Divas were delighted at each new color since they had no idea which color they would get.

2. Add baking soda to each spoon - I was generous since I wanted a big reaction.

3. Add vinegar to each cup - I filled our cups 2/3 of the way
I wanted it to fizz, pop & overflow for dramatic effect!

If you prefer less mess you can fill it up half-way or less -
but I say use a tray & GO FOR IT!

smelling the vinegar to see if they could guess what it was

4. Pick a spoon & drop the baking soda into the cup
we needed to stir a bit to get the food color going.

Her reaction to the 1st one was PRICELESS!
They LOVED it!

Nothing beats a good colorful explosion!

Of course the Lil Divas wanted to see what happened if we added more baking soda after the fizz had died down. So that's exactly what they did. They added lots & lots more baking soda.

The cups bubbled and fizzed again but not as big
so they decided they needed more vinegar.

Adding more vinegar gave us lots of fizzy overflow!

The Lil Divas excitement over this experiment never waned.
Below, is the last shot I took of them before saying we had to clean -up!
They still marveled over the reactions caused by the baking soda & vinegar.

What a successful experiment!

Here's what I was left with to clean up!
Not bad for such excitement & fun -
I was glad I used the deep tray!

If you are interested in the science behind this fun experiment -
basically the baking soda and the vinegar create an acid-base reaction
and the two chemicals work together to create a gas - carbon dioxide.

Stay tuned for a few neat variations of this in the coming week.



    I hope I don't wait a year to do this.
    I will do this! (-:

  2. oooh thats looks fantastic! I can't wait to see what else you have come up with!

  3. Adding the colors make the effect so much neater. Especially since its hidden under the baking soda. Very cool.

    1. The 1st one was priceless when they saw it change color. After that, it was hilarious to see them trying to guess what color it would be. Thanks for stopping by.

  4. Love the pic of your daughter's face when she sees the first one! Totally priceless. We had fun doing this for the 30 Days To Hands On Play challenge, but didn't add the food coloring - the kids will love this one! Thanks for sharing :-)

  5. Wow! What fabulous expressions!!! Definitely priceless. What fun fun fun!!!!! We need to start doing some experiments!

    Thank you for sharing on Kids Get Crafty!


  6. Oh this looks fun, kiddo would love this. Bookmarking for our To Play list!

    1. It's a great one to just explore and have fun with. Kids love the reaction and it's easy for them to do.

  7. We did this too last year and it was soooo much fun!!! I haven't done this with my class this year yet! On our list to do!!

  8. So much fun! We did this without the colors (love that addition) and it will be posted Monday. Kids love science! Vicky from Mess For Less

  9. Soooo cool! I think I would make my next week's lesson plans from your super creative posts!! Thanks so much for sharing all your creativity with all of us =-)

  10. I love this and look forward to trying it. My little one will be thrilled with this activity!

  11. Fun fun fun!! I love the colors. Thanks for sharing at AfterSchool.

  12. Such fun, visual science! Thanks for linking up to Afterschool =)

  13. I've never seen that done with added color. Very cool idea! And i love how you hid the color on the spoon.

  14. This is so clever, especially adding the colors. Thank you for sharing. :) We will be trying this one out. fun fun. Enjoy your day.

    1. nice to have you with us. I hope you get to try the experiment & enjoy it. This one was super easy and fun

  16. Ooohhhh, great idea to hide the food dye.

    Thanks for linking up to Science Sunday!

  17. Thanks for posting this! My kids loved it!

    1. so glad they enjoyed it. It is a cool one for kids to do & see!

  18. Oh, how fun! I love adding color to this experiment. The photos are priceless!

  19. Oh, how fun!! Thank you for sharing at Sharing Saturday!!

  20. my boys are really in to these bi carb and vinegar experiments at the mo. we have been adding lots of science to our blog recently! Like the idea of this too. will be letting him try this one too! Thanks for sharing xx

  21. Great pics really had a great science exploration week!

  22. We did this this morning and really enjoyed it. Thank you! You have some really neat ideas and it is joy to see what you are upto. Only a few things work for my own children sonce they are older--but the ideas that are for the younger children I file for future use with my daycare children. I ran a daycare for 11 years and am closed to spend time with my own family for awhile. Thanks again.

  23. thanks for the wonderful ideas for kids. My kids are going to love trying this. I am happy to be your newest follower. When you get a chance check out my food blog

  24. Love it. I run a home daycare and will be doing this tomorrow with the kids.

    Thank you,


  25. Wow so much cool FUN! I LOVE when learning and fun become one!!!

  26. im 75 now but my brother and I used to do this and we called it homemade soda pop, lol

  27. i say add some hard boiled eggs and color them.....double duty!!!

  28. The expression spoke volumes. We had a major disaster today with my son's fancy volcano science kit...nothing happened. Tomorrow I'm breaking out the baking soda and vinegar to give the eruption real oomph!

  29. Just stopping by to let you know that I've featured your craft on Family Fun Crafts! You can see it here:

    If you have other kid friendly crafts, I'd love it if you would submit them. :) If you would like to display a
    featured button on your site, you can grab one from the right side bar of your post above.

  30. going to do this tonight. Thanks for the idea. My kids are going to be so amazed. They are 4 and 2!

  31. We love baking soda and vinegar at our house! My 3-year old calls it his 'science experiments'. Always fun to see their reactions!

  32. amazing !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!;:):):)

  33. Just did this with my 4 kiddos ages 8-12. Got a different reaction from each of them. My 8 year old surprised me the most by wanting to mix colors after the fact to see what new colors she could achieve. She amazed herself by making a brown that resembled root-beer. Thanks for the great ideas.

    1. very cool, it's wonderful when they just "go" with something and let their curiosity take them places, isn't it?

  34. I'm a preschool teacher and we do this often. Another extension is to use different flavors of koolaid. It doesn't change the reaction, but the smell. We give the children a small cup with vinegar, a dropper, one with baking soda and another with a package of koolaid, a spoon and let them explore.This is great in a 6 count muffin pan so they have 6 different sections to have reactions. Also, for a different activity, we use a baking dish, like a 9x13 and pour an inch of baking soda on the bottom and give them colored vinegar and droppers. Tons of fun!

    1. Oh, we have done the kool-aid & my girls LOVE it! It is fun - I hid the colors under some baking soda and made them guess the flavor once they got their eruption. It was lots of fun. I shared it on the blog here -


    Thanks for the inspiration!!

  36. Hi what can they do with the mixture afterwards? I feel its such a waste of so much vinegar :(

  37. Found this on Pinterest - Worked awesome for my group of 4 little boys- all 5 years old. They squealed every time it flowed over!! Definitely a good idea to have the deep pans. I'd also recommend getting the big gallon jug of white vinegar at Walmart. After we were done "exploding," we mixed the colors together and predicted what colors it would make. Thanks!!

  38. I can wait to try this experiment with my preschoolers , it looks so much fun, thank you.

  39. wow

    I wanna try this!
