This week we were inspired by the Instagram community to have fun making things fizz! Little C loves everything extremely colorful, and I had some brand new silicone bug molds that were calling my name, so of course I had to make colorful baking soda bugs! I also have my tried, and true, flower molds, and heart molds that I like to use every time I get a chance.
First came the prep work, Little C helped me stir baking soda, water, and liquid watercolors together in separate bowls. There aren’t any exact measurements to the mixture, you want to mix in just enough water to make a thick paste. In the picture above, there is still a little too much water in the mix. I had to add a few more small spoon fulls of baking soda, but you really can’t go wrong. Some of mine were a tad watery, and they still created plenty of fizz.
Little C, and I poured, scooped, and shoved the mixtures into the molds. I tried to keep all the colors separate, which is pretty easy to do, if you don’t have a two year old helping you! In the end, I decided to bring out our heart molds, and let Little C shove all the left overs into it. I like to give her free reign after she helps me do things the way I want them done. She loved being able to freely handle, and explore everything. I love having her participate as much as possible, because she feels so proud when she sees the end result of a project that she helped with.
After filling up our molds, we popped them in the freezer overnight. The next morning, we grabbed a big storage bucket, and filled it with our frozen baking soda creations, all the vinegar in the house (one large gallon, and one small pint, though we could have used two huge gallons of vinegar easily!), some small bowls, and some squeeze bottles.
When we got outside, we lined up the baking soda flowers in rainbow order, and I let Little C squeeze a little vinegar into each bowl, and watch the reaction fizz up to the top of the bowls. The colors were gorgeous! Then I lined up all the bugs, and let her have fun watching the bugs fizz.
After my beautifully scripted, and organized version of this activity, I decided it was time for chaos, because doing everything unscripted is always the best recipe for fun. (I’m working on loosening up, making messes, and going with the flow.) We dumped all the bowls out, and had fun watching all the colors, fizz together, as Little C went crazy squirting vinegar far, and wide. What kid doesn’t like pouring, and squeezing things out of squeeze bottles?
We even decided to squeeze vinegar into the heart molds, and watch the left over vinegar bubble up.
Soon all the vinegar was gone, but that didn’t stop our fun, there was a lot of colorful mounds of soggy baking soda left over, just waiting to be smashed, and smeared all over the driveway.
When it was time to clean up, we just hosed down the driveway, and I filled our big storage container with water, so Little C could, “wash the dishes”. I always like to have her help me clean up, and if I make it fun, sometimes she actually does at least half of the work.
If you don’t have a driveway, you could always just do this activity inside in a large storage bin. I am sure a big bin full of colorful fizzing baking soda would be just as beautiful! You could also do this with regular ice cube trays, instead of special molds, but I invested in a few different molds, and I have used my molds for several different activities. Check out how we made flower shaped sidewalk chalk with the same flower molds we used in this activity. This is definitely an activity your kids will love!
