Exploding Baggie


exploding baggie


Boom! What kid doesn’t like explosions, right? Here’s a simple science activity we did recently that’s a twist on the old baking soda and vinegar volcano. This time, we harnessed the power of the reaction caused by the chemicals combining to create a “mini-bomb” as Trevor called it.

Want to try it yourself?

You’ll need:

  • A small zipper sandwich bag
  • Baking soda
  • Vinegar
  • Warm water
  • Measuring cup
  • Tissue


  1. Pour ¼ cup of warm water in the bag.
  2. Pour ½ cup vinegar in the bag.
  3. Wrap 3 teaspoons of baking soda in the tissue tightly.
  4. Zip bag almost closed, pop the tissue in, and seal it the rest of the way.
  5. Set the bag down and step back.

If you want to include the instructions in your child’s science notebook, I created a printable you can download below. Remember, too, that this is just an activity. If you’d like to make it an experiment and guide your child through the scientific method, check out the suggestions for adapting the activity at the bottom of the printable.
