We started with Ooos and Aahhs over bubbling and fizzing, and ended with Wows and Eeews over oozing and goozing today! What a messy, messy, fun, and exhausting day!
I’ve been wanting to revisit the vinegar and baking soda experiment for a few weeks now, and today’s chilly, rainy weather was the perfect backdrop for it. I finally picked up some bottle dispensers from Walmart that I’ve had my eye on for quite some time. They were less than a dollar each, and I just knew they’d be the perfect vehicle for our vinegar!
Now, I don’t hate the smell of vinegar, but I don’t love it either. I had read somewhere online that adding a bit of peppermint oil to vinegar could mask the smell, so we gave it a try—and whaahh…laa, no vinegar smell! It really worked! Instead of bearing the scent of vinegar during our play, we got to enjoy the relaxing smell of pure peppermint oil. Definitely a win!
We filled our dispensers with vinegar, added a few drops of food coloring, and two drops of peppermint oil, then got to work. I evenly dispersed a small box of baking soda onto clear disposable tops left over from our Thanksgiving baking.
The kids were so eager to start experimenting! I was a bit worried that they’d hastily empty their dispensers, and the fun would be over just as quickly as it began. So, I asked them to carefully let the vinegar solution come out on its own (eye droppers would have been loads of fun too!). It really made me laugh at how well they listened to my request. Not that I didn’t expect them to, but I’m not sure I would have been able to resist the temptation to just squeeze! Oh, how I love my babies. They practiced such great self-control. :)
Look how nice and neat it begun...haha!
Gabriella said it sounded just like Sprite fizzing away. :)
After I gave them the go-a-head to squeeze, their excitement heightened and new level fun began!
They squeeeeezeed until there was no squeezing left to be done. Once we were out of vinegar Gabriella noticed the layer of baking soda that remained was perfect grounds for drawing.
Mikey joined in as well...

The vinegar and baking soda experiment was lots of fun, and we’ll most definitely do it over and over, but to be quite honest, I was pretty sad that the fun was over so quickly. I love doing experiments with the kiddos, but with all the effort it takes to prepare, I’d like to spend a bit more time exploring. Sooo, feeling ambitious, I reached for the cornstarch!
If you’re ever up for experimenting with messy sensory play, give cornstarch a try! It’s my go-to when we finish any liquid sensory play, and I was curious to see what adding cornstarch to our vinegar would do. Cornstarch is amazing!
We’ve added cornstarch and water to pumpkin clay before Thanksgiving, and oh my goodness, that was messy, messy, messy! Haha! Not sure I’ll be doing that combo again anytime soon.
I wasn’t sure what would happen when I added cornstarch to our vinegar, but ohhhh, was it perfect! It turned into the most delightful Oobleck.
Getting Oobleck to the right consistency can be a bit tricky. You may have to experiment with how “loose” or “thick” you want it. If you’ve never played with Oobleck before, please, do! Yes, it’s super messy (at least it is the way my two-year-old plays), but it is SOOO much fun! It acts both as a solid and a liquid. There are some great step-by-step instructions for making Oobleck here. The term Oobleck comes from Dr. Seuss's book, Bartholomew and the Oobleck. Having literature to extend or preface experiments or playtime makes it all the more exciting! This momma is all about making connections. :)
Gabriella was fascinated (I was too!) with making large rocks, then watching them melt right before her eyes!
Mikey enjoyed watching his hands sink into the solid-liquid substance. He'd pull them out and watch it ooze from his fingertips. He did this over and over! :)
We made a huge mess! I can’t believe I actually made a photo collage of just messy pictures!
Here’s a helpful tip for cleaning... set out a bowl of warm water (I set one close to each of them) for rinsing hands and arms. That’s it! I’m not sure why I never thought of this before, but oh, was it helpful. You DO NOT want to carry Oobleck-covered kiddos from the play area to the kitchen sink or bathroom for cleanup. You won’t be able to move faster than Oobleck oozes. Believe me, I tried. Haha! You’ll end up with little droplets of Oobleck everywhere. While it’s not hard to clean up, it’s just easier if the mess is confined to one area.
Mikey enjoyed using his bowl of water to make his Oobleck as runny as possible, then covered every inch of his arm with it! Oh, my Mikey!
This messy play would have been ideal on a sheet/towels on the floor but if you end up with a mess like I did just use a fresh bowl of warm water and a rag to wipe up the rest. Clean up really is that easy, promise!
I'm going to end this post with my favorite picture from our messy play day...
Just look at those whittle feet and those toes!!!! Oh, so cute!
