Nothing like a little chemistry to to add fun to a boring afternoon. What happens inside the bag is actually pretty interesting &#8211; the baking soda and the vinegar eventually mix (the tissue buys you some time to zip the bag shut) When they do mix, you create an ACID-BASE reaction and the two chemicals work together to create a gas, (carbon dioxide &#8211; the stuff we breathe out) well it turns out gasses need a lot of room and the carbon dioxide starts to fill the bag, and keeps filling the bag until the bag can no longer hold it any more and, POP! Be sure to clean up well and recycle those plastic bags&#8230;have fun!<\/p>\n<p><strong>MAKE IT AN EXPERIMENT<\/strong><\/p>\n<p>The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:<\/p>\n<ol>\n<li>Will different temperature water affect how fast the bag inflates?<\/li>\n<li>What amount of baking soda creates the best reaction?<\/li>\n<li>Which size bag creates the fastest pop?<\/li>\n<\/ol>\n<p>P.S.
