Pop Pop Fizz Fizz

In another impromptu Pinterest foray this past week, the kids and I dabbled in chemical reactions.  Specifically baking soda and vinegar so I’m not sure if that counts as a “chemical” reaction, but it killed 30 minutes.  And like all of my ‘Pins’, it’s super easy and requires little in the way of materials.

Here’s what you need: baking soda, white vinegar, paper towels and zip lock sandwich bags.  Seriously that’s it.  If you’re feeling sassy, throw in some food coloring.

Take a paper towel and cut it into quarters so you have roughly 5″ squares.

Put 1 1/2 tablespoons of baking soda in the middle of each paper towel square and wrap it up burrito style so you have a little baking soda package.

Pour 1/2 cup water and 1/2 cup vinegar into your ziplock.  We added food coloring too, because if there’s anything we’re feeling at the Smith house, it’s sassy.  (I also misread the directions which actually say to add less water… but this worked fine for us!)

As soon as you drop the baking soda/ paper towel package into your ziplock, you’re going to see some action, so be ready to seal the ziplock as fast as you can.

I held the paper towel wrap right inside the ziplock so it wasn’t touching the liquid, then sealed the bag and let ‘er drop.

Once the baking soda hits the vinegar, it’s game on.  The gas released from the baking soda/ vinegar combo will eventually pop the ziplock bag  to the oohs and ahhs of the toddler crowd.

At first they were anxious about the “pop” but they got over that pretty fast.

We did four in all and both kids were thrilled.

I emphasize “both” kids here, because that’s not always the case around here; Sesame Street, our plasma car, and poking Martha are just a few of the activities that entertain both Eleanor and Oliver.  And now, our exploding bags.
