1. I started off by weighing the plastic plate I was using to weigh the Baking soda which weighed 2.47g.

2. I added measured the plate with Baking soda until I got 5.47g

3. When I subtracted the total weight by the weight of the plate I got 3.0g, which was the exact amount I needed.

4. I used a graduated cylinder to measure 42.8mL of Vinegar which is the amount I calculated.

5. I then divided the Ziploc bag into two halves. I poured the Vinegar on one side and the Baking soda on the other.

6. Once I sucked the air out, I mixed both the Vinegar and Baking soda together and within a matter of seconds, saw the reaction occurring.

7. The reaction cause rapid fizzing and the bag quickly started expanding.

Within 15 seconds the bag was completely blown up and the fizzing had stopped.
