- poured the vinegar into the Ziploc bag
- folded the Ziploc bag in half hamburger style
- poured the baking soda into the top half of the Ziploc bag
- we made sure the baking soda and vinegar didn't mix at first

- We then mixed the baking soda and vinegar and layer the bag down
- after we mixed the baking soda and vinegar the mixture turned into a white/milky/bubbly liquid
- after the liquid settled, the bag started expanding
- after about 1 minute the bag fully expanded
