Flatulence Fun Human Body Science Experiment
In this fun and easy human body science experiment, we’re going to explore flatulence by using a chemical reaction to create enough gas in a bag that it explodes.
Materials:
- Ziplock sandwich baggie
- Measuring cups
- Measuring spoons
- Tape
- Baking soda
- Vinegar
- Toilet paper
Instructions:
- Go outside as this experiment is messy.
- Put one half cup of vinegar in the baggie.
- Put one tablespoon of baking soda on a square of toilet tissue.
- Fold the toilet tissue and tape it closed.
- Drop the pouch of baking soda in the baggie and zip the baggie securely closed.
- Quickly shake the bag a few times and set it on the ground.
- Step away and wait a few moments.

How it Works:
The baking soda is a base and the vinegar is an acid. When an acid and base are combined, a chemical reaction occurs that produces carbon dioxide gas. The carbon dioxide is trapped in the baggie. The pressure will build until the baggie pops. Flatulence or farts are also made of gas. Small amounts of gas are swallowed while you eat food and other gas is produced while the food you eat is being digested. All these gases build up and leave the body as flatulence.
Make This A Science Project:
Try filling the baggie with different types of mushed up food and see if some foods produce more gas than others. Add carbonated soda to the experiment. Try the experiment with an Alka-Seltzer tablet.
