Friends, I don’t know about you, but I love baking soda and vinegar projects. This activity took a few days to get ready but it was so fun that I think it was completely worth it. I found that the original plan wasn’t nearly as exciting as what Maddy had in mind as she worked through the activity.

Baking Soda
Paint (I used washable)
Mini Cupcake Pan

First, decide how much paint you will be making. I had a lot more than I expected but it worked out with how big my muffin pan was. I used about 3/4s of a small box.

Add water and stir but watch for consistency. You want it to be a paste, not completely watered down.


Then spoon the paste into the muffin pan.


Next, add paint to the paste. The amount of paint depends on how bright or soft the desired color should be.


Stir, stir, stir.


Once the paint is stirred in, allow the pan to sit overnight. The next morning, dump out the water sitting on top and allow to sit at least until the evening (I had it sit overnight again). The result will be a hard block which is exactly what you want.


Next is the activity!

Gather something to hold the vinegar and pour as much in as you would like.


I looked all over for the paintbrushes I know we have but I couldn’t find them so we improvised! I had the kids use their fingers instead which actually made this more sensory friendly – big win!



Oliver was over it pretty quickly but Maddy stayed close. I gave her a foam letter to “paint” with which held more vinegar because the bubbling reaction wasn’t working well with fingers.


Maddy soon discovered that if she dropped some of the paint in her vinegar cup, the vinegar would bubble. This where the real fun began!



She played like that for a little while, then tried pouring some vinegar straight into the muffin pan and the result was glorious.




The painting part may not have worked out as well as I would have liked, but the exploration and fun was at an all-time high. I give two big huge thumbs up for this activity.

This one isn't going on the fridge. :)
