Exploding Baggie


  • Gallon-sized zip-top bag
  • Food coloring
  • Binder clip
  • 1/2 cup vinegar
  • 1/4 cup baking soda
  • Safety goggles

What to Do

  • Put on safety goggles.
  • Pour vinegar into the zip-top bag and add a drop or two of food coloring.
  • Twist the baggie just above the liquid and secure it with a binder clip, leaving space at the top.
  • Add the baking soda to the top portion of the bag. Seal tight!
  • Set outside or on a covered table. Have paper towels handy!
  • Remove the clip, allowing the baking soda and vinegar to combine. (Give a little shake if needed.)
  • Step back, and watch it inflate…and explode
