How much gas does your favorite beverage produce
My hypothesis was correct, the soda produced the most gas faster than the others and the balloon was bigger than all the others. As soon as I added the vinegar to the beverages the one with the soft drink immediately started a reaction and the balloon that was used to see the gasses started getting bigger almost immediately.
After doing this experiment I can conclude that carbonated drinks/sodas, have a high probability of producing gases in the stomach. I believe that lactose drinks like milk are a base that will produce least gas.
I hypothesize that the beverage that already has gas in will produce more gas than the others

I'm testing the different gases of my favorite beverages by using different beverages like milk, juice, water and soft drinks. I added vinegar to copy the acid in our stomach and observed then for a period of time while in warmth to make it like the same condition as our stomach temperature.I'm interested in this project because I wanted to see how much gas the beverages would produce in the stomach.
Pour an equal amount of each beverage into separate plastic bottles.
Mix a couple teaspoons of vinegar into each beverage. The vinegar will represent your stomach’s acid.
Blow-up and release the air in a balloon for each bottle. This will stretch the balloons so they are more easily inflated.
Stretch the open end of a balloon over the opening of each bottle.
Place the bottles on a warm heating pad.
Observe the balloons at different intervals as the liquids begin to heat.
Which liquids have inflated balloons? Which balloons are inflated more than the other balloons? How is the inflation of each balloon related to the amount of gas produced by the liquid?

At first I used a heating pad to heat up the the bottles, but it was not working. I then used a pot with hot water at a stady 150 degrees and placed the bottles inside with water up half an inch. I let them sit in the hot water while taking temperature and making observations for reaction. My results could not be as good as real results in a stomach but the results did indicate that carbonated drinks produce more gasses. This experiment taught me that orange juice and milk don't really produce gas, but water produces alot mare than i thought
