2. Mix vinegar and warm water and pour into bag. Partially seal the bag — leave enough of an opening to put in baking soda packet.

THIS IS THE IMPORTANT PART: CAREFULLY DROP THE PACKET INTO THE BAG. IMMEDIATELY SEAL THE BAG. SET BAG QUICKLY DOWN AND STAND CLEAR!!!!

Watch Chemestry in Motion! Do you know what happened??

The vinegar and baking soda combined to produce CARBON DIOXIDE!  The Carbon Dioxide inflated the bag until it burst the seams with a loud POP!!!

What did your bag do?  One time I did it, I didn’t seal the bag fast enough so not enough Carbon Dioxide was created to pop the bag.  The bag just stayed puffy!  Which was kind of cool too!

But the next time I did it, this is what happened:
