Exploding Bag!

Exploding Baggie Experiment

Materials: Ziploc bag, binder clip, food coloring, vinegar, baking soda, big bowl

  1. Measure 1/2 cup of vinegar into a Ziploc bag and add a drop or two of food coloring

  2. Twist the baggie just above the liquid and secure with a binder clip, and leave space at the top to add the baking soda

  3. Add 1/4 cup of baking soda to the top portion of the Ziploc bag and seal the bag

  4. Put the bag into the big bowl and remove the binder clip. Watch the bag inflate!

In this experiment when vinegar and baking soda mix together, you notice that the solution starts to fizz and bubble. When mixing these two things together a chemical reaction is happening. This happens because carbon dioxide gas is being produced in this reaction and quickly foams up in the bag. As the carbon dioxide is being produced it fills the baggie until the pressure builds up and causes the bag to explode.

The reaction is:

NaHCO3 + CH3COOH --> CO2 + H20 + NaCH3COO

Carbon dioxide is produced which is seen through the bubbles. All of the solid eventually ends up dissolved to create a new liquid.
