Bubble Bomb

• How I was able to pop a plastic bag with the
  power of fizz!
• By Student A

2
Question..

• Can I pop a plastic bag by using elements that
  are known to me?

3
Questions.

• Using my background knowledge about chemical
  reactions, I know that vinegar and baking soda
  mixed with water can become explosive because I
  know that this will make carbon dioxide, a gas
  that will react with the baking soda.
• But, how much of each element will I need in
  order for the chemicals to pop the plastic bag?

4
Hypothesis

• I know that if I mix one teaspoon of vinegar with
  baking soda I will get a small volcano eruption.
• A plastic bag is much stronger.
• I hypothesize that I will need 2 tablespoons of
  baking soda, 1 cup of vinegar and 1/2 cup of
  water to blow up the bag.

5
Procedure.

• First, I collected all the materials I would
  need
• Vinegar
• Baking soda
• Measuring spoons
• Measuring cup
• Zipper lock plastic bags

6
Next,

• Next, I had to have a place where I could make a
  mess and let the bag explode.
• (My mom wouldnt let me use the kitchen so I
  went into the shower stall and closed the shower
  door.)

7
Procedure/details..

• After I collected all the materials, I put the
  following together in this order
• Pour 1 cup vinegar in plastic bag
• Pour 1/2 cup of water into plastic bag
• Quickly pour the baking soda in 2 tablespoons
  already measured out and in a beaker.
• Quickly zip bag
• Shake the bag a little
• Put bag on shower floor and stand back!

What happened?

• Data collected
• Bags- It took awhile to find the right bag. Some
  of the bags leaked so I had to test the zipper
  lock bags by putting water into it.
• Baking Soda-When I put the baking soda into the
  mixture, it immediately fizzed up to where I
  couldnt zip the bag!
• So, I had to put the baking soda in a Kleenex and
  wrap it up and then put it in the bag. That
  helped delay the reaction!

9
Results.

• The ingredients that I hypothesized that would
  break the bag worked! It popped in the shower
  after 35 seconds of fizzing.

• I did have to change how I put the baking soda in
  the bag by wrapping it in Kleenex.

10
Conclusions..

• The bubbles in the bag filled with carbon
  dioxide, a gas that forms when the vinegar reacts
  with the baking soda.
• The amounts of those 2 elements were needed to
  have enough force to pop the plastic bag.

11
Questions I have

• Would this same mixture be able to blow up foil?
  Or, would it take more baking soda?
• Would I be able to unclog a sink with this
  mixture?
