Exploding Stomach Human Body Science Experiment
In this fun and easy science experiment, we’re going to explore and investigate the human body by creating an exploding stomach.
- A tissue
- Baking soda
- A zip close style sandwich baggie
- Warm water
- Measuring cup
- Head outdoors or work in the kitchen sink as this will make a little mess.
- Add 1/4 cup of pretty warm water into your zip close baggie.
- Add 1/2 cup of vinegar into the warm water inside the bag.
- Now add 3 teaspoons of baking soda into the center of the tissue.
- Enclose the baking soda in the tissue by wrapping the tissue around it and making a little bundle.
- You will now need to work quickly. Slightly zip the baggie sealed but leave adequate room to add the tissue wrapped baking soda bundle. Place the tissue bundle with the baking soda into your baggie and immediately zip the baggie completely closed while insuring it is sealed tightly.
- Put the baggie in the sink or down on the ground if you are outside and step away. The baggie will begin to grow and expand and if sealed properly it will soon pop loudly.
How it Works:
In this fun little demonstration the baggie acted as our pretend stomach. The vinegar and baking soda soon mixed and caused an acid and base chemical reaction which created carbon dioxide. The pressure created inside the baggie soon reached a point that caused the bag to fail and if everything went correctly you heard a loud Pop! This demonstration should get you thinking about the possible chemical reactions that occur in your own stomach.
Make This A Science Project:
Try different temperatures of water. Try different types of baggies or containers. Add different amounts of baking soda.
