Concoctions for Play: Fizzy Explosion Bags

Fizzy Explosion Bags
Over the years we have had much fun with the chemical reaction that occurs between baking soda and vinegar. When they were young, they just played/experimented with the two, often also with a package of liquid food coloring, pretending to be a scientist or a magician. As they each got a little older, they learned why this reaction occurs. Playing with this reaction never ceases to be fun, though, even if you know why.
When I saw this variation of this theme on Superheroes and Princesses, in which the goal is to make a sandwich bag pop with the power of baking soda and vinegar, I knew my boys would enjoy this as a summer activity.
You can see the already made packets on the left.

Tear a paper towel into a square that measures about 5 inches by 5 inches. Put 1 1/2 tablespoons of baking soda in the center of the square, then fold the sides of the square in toward the middle, and then the opposite sides in toward the middle, with the baking soda inside. This is your "time-release packet."



Pour into your plastic bag, 1/2 cup of vinegar and 1/4 cup of warm water.
Now here's the tricky part. You need to drop the time-release packet into the vinegar and zip the bag closed before the fizzing gets out of control. You can zip the bag halfway closed, then stuff the packet in and zip the bag closed the rest of the way in a hurry, or you can put the time-release packet into the mouth of the bag and hold it up out of the vinegar by pinching the sides of the bag. Zip the bag closed and then let the packet drop into the vinegar. One way or another, get the packet in the vinegar and zip the bag closed.


Shake the bag a little, put it in the sink or on the ground, and stand back! The bag will puff up dramatically and then give a satisfying pop sound.




"POP!"
Be prepared to do this several times.
But despite the fact that Pinterest has been circulating the idea that these take off like rockets, they do not, they just pop nicely.

  1. This is so fun! I have to return to soda and vinegar one of these days when my mess tolerance level is high... or do it outside like you do.

  3. This looks like something fun for Jeremiah and maybe even Bethany if she'll stick around long enough to see the reaction! I see you wear your glasses on your head too, Phyllis! LOL!!

    1. I did wear my glasses on my head a few years ago before I got prescription glasses...now I have to wear them all the time.

  5. We really have to try this, we have done it in a bottle with a balloon over the top and popped that before, this is a little different.....there is just something satisfying in making things explode like this in science:)

  6. We just did this, I think our bags were too big, so we ended up using 2 cups of vinegar and 1/2 cup bicarb with no water...exploded really well:)
