Exploding Lunch Bag!

How many times have you wished whatever your mom put in your lunch would just explode so you wouldn't have to eat it? Well this experiment shows you how to do just that! This was another one that had to be done outside. We got this idea from http://www.sciencebob.com/



Materials needed:

~ Measuring cup
~ A sanwich sized baggie
~ One Kleenex
~ Baking soda
~ Warm Water
~ Vinegar

Procedure:

1. Put 1/4 cup of warm water into baggie.
2. Add 1/2 cup of vinegar into the baggie.
3. Put 3 tsp of baking soda into the kleenex by folding the kleenex around it
4. Quickly zip most of the baggie with leaving only enough space to add the baking soda kleenex. QUICK QUICK zip the baggie completely closed.
5. Step back and watch... POP!

This works because 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 - 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...have fun!

The project above is a DEMONSTRATION. To make it a true experiment, you can try to answer these questions:

1. Will different temperature water affect how fast the bag inflates?
2. What amount of baking soda creates the best reaction?
3. Which size bag creates the fastest pop?
