Exploding baggie science-2

In this science experiment for kids, students will discover what happens when you mix baking soda with vinegar!

Materials:

  • Clear sandwich bag
  • Tissue
  • 3 tablespoons baking soda
  • 1/4 cup of water
  • 1/2 cup of vinegar
  • Liquid watercolors or food coloring (optional)

Instructions:

  • Add the water, vinegar and any coloring to the bag.
  • Unfold a tissue and add the baking soda to the center of the tissue. Fold it into a little square so none of the baking soda falls out.
  • Go outside or set the baggie somewhere that can get a little messy. Open the corner of the bag and stick the tissue with the baking soda in it inside. Quickly re-seal the bag and stand back to watch!
  • As the tissue gets wet the baking soda begins to mix with the vinegar and the bag starts to inflate with carbon dioxide.
  • Until the pressure pops the bag and it “explodes”!
