Common Beverages Produce Gas

By: Austin Brandt

Purpose Statement

The purpose of this experiment was to see how much gas is produced in common beverages. I became interested in this experiment because I would like to see if pop has more gas in it than other drinks/beverages. The information gained from this experiment will help others by showing how much gas is released by beverages to affect you stomach.

Background Research

Common beverages produce gases into your stomach. Beverages like milk, soda, juice, etc. produce gas that enters into your system. Each beverage releases gas in different percentages or amounts. Vinegar helps start the reaction of gas in a beverage. Vinegar has a combination of several vitamins, mineral products, and fats which will react with the beverage of your daily use.


Soda is made up of carbonated water, which is simply water that has had carbon gas more or less injected into it, high fructose corn syrup, phosphoric acid, and caffeine. Milk is made up of carbohydrate (lactose), fat, protein, vitamins and minerals, enzymes, and related to milk composition. Orange juice is made up of all water, sugar, and citric acid. Water is made up of hydrogen ions linked to hydroxyl ions to form H2O.

Hypothesis

My hypothesis is Mountain Dew will produce the most gas. I base my hypothesis on this because I thought Mountain Dew has more carbon gas in it and it just seems more likely for it to produce more gas.

Materials

Plastic Bottles

Balloons

Vinegar

Heating Pad

Variety of Beverages

Measuring Tools

IV- Beverages

DV- How much gas is produced in common beverages

CV- Amount of each beverage, amount of temperature, and the plastic bottles they are put in.

Procedures

1. Pour an equal amount of each beverage into seperate plastic bottles.

2. Mix two teaspoons of vinegar into each beverage. The vinegar will represent your stomach's acid.

3. Blow-up and release the air in a balloon for each bottle. This will stretch the balloons, so they are more easily inflated.

4. Stretch the open end of a balloon over the opening of each bottle.

5. Place the bottles on a warm heating pad.

6. Observe the balloons at different intervals as the liquids begin to heat.

7. Observe what liquids inflated the balloons. Find out which balloons inflated more than the others.

Observations Log/Data

Start Time: 11:18 a.m. (Put on heating pad). Heating Pad level 6: (highest)

Beverages with vinegar mixed in and balloons on top did not show any progress for 20 mins so moved over to the oven in hot water.

Put on oven at 11:39 a.m. on level 8. Balloons were only put on for 10 mins.

Balloons started to inflat at their own rates.

Results

The original purpose of this experiment was to see which beverage would produce the most gas. The results of the experiment were soda (more specifically caffeine free Purple Fanta) can produce the most gas. The beverages that produced in the middle or average was Mountain Dew, Water, Orange Juice, and Mountain Berry Powerade. The beverage that produced the least was the Vitamin D Milk.

Conclusion

My hypothesis was Mountain Dew would produce the most gas. The results indicate that this hypothesis should be considered wrong because the caffeine free Purple Fanta actually produced the most gas. Based on the results of the experiment expect more gas in caffeine free beverages. If I were to conduct this science fair project again I would use more caffeine free beverages.
