Myth (describe your myth)
Exploding Pop
Our myth is talking about how if we tap the top of a shaken up/dropped soda can then it will not fizz over.



The most common ingrediants in soda are: Carbonated water, high fructose corn syrup, caramel color, phosphoric acid, natural flavors and caffine.
Carbonation is the process of dissolving carbon dioxide into water. It usually involves carbon under high pressure.
Carbon Dioxide is a chemical compound composed of two oxygen atoms bonded to a single carbon atom. It makes the soda stay fresh longer. Its chemical formula is CO2.

Pressure is a force being pushed against or on something.
Kinetic Energy is the pressure and energy built up from the carbon dioxide force in the can.
Molecules are a group of two or more atoms that stick together.

Liquid is a substance that is neither a solid nor a gas.
Gas is an air-like substance that expands to fill the space it is in.
Solute is a substance that is dissolved in another substance.
Solvent is a liquid substance used to dissolve other items.
Boyle's Gas Law describes the proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept consistent within a closed system.
Charle's Gas Law is an expiramental gas law which describes how gasses tend to expand when heated
  • Question # 1-Q: How does the soda company get the "gas" into the liquid (carbonation)?
A: Carbon dioxide is bubbled through cold water until it reaches a saturation level.
  • Question # 2-Q: What actually happens to the molecules of "gas" pressure is released from the can?
A: They release the pressure inside the can and begin to fizz and bubble.
  • Question # 3-Q: What is the difference (with the molecules) between a gas and a liquid?
A: The molecules in a liquid state interact with eachother and cannot be compressed. The molecules in gas don't interact with eachother as much making the gas thinner, although they can be compressed.
  • Question # 4-Q: Why does the soda company add carbon dioxide to the soda?
A: They put in to preserve the soda and to give it a light, fresh, bubbly taste. It gives it a more interesting and tasty flavor so people want to buy it more.
ASPATAME: An ingredient that replaces the sugar in soda. ONLY diet soda has it!! We think it may have an effect on the fizziness of Diet Sodas.

Small scale procedure #1:
Question: If we put soda into a clear plastic cup and tap the side will the bubbles pop?
Materials: Clear plastic cups, Mt. Dew, Diet Mt. Dew
Independant Variable: Kind of soda
Dependant Variable: If the bubbles pop when we tap them.
Constant Variables: How many times we tap it.
Hypothesis: If we tap the side of the cups, the bubbles will pop because of the movement and vibrations caused by the tapping on the side of the cup.
1.Pour 50mL of Mt. Dew into one cup and 50mL of Diet Mt. Dew into another.
2. Choose one to start with and tap the side 10 times.
3. Record results of bubbles popped.
4. Repeat steps 2 and 3 for next cup.

Conclusion: The conclusion for small scale test number one is that diet soda is more fizzy and the bubbles didn't pop. We know this because the bubbles joined together and got stronger and wouldn't pop in the diet. In regular Mtn. Dew the bubbles just floated up to the top when we tapped it and didn't do anything after that.

Small Scale Procedure #2
Question: Which soda is fizzier? Which soda has a greater chance of exploding?
Materials:Regular Moutain Dew, Diet Mountain Dew, Tape Measure.
Independant Variable: Kind of soda.
Dependent Varible: How far the soda explodes and which soda seems to be fizzier.
Constant Varible: Distance we threw it.
Hypothesis: When we throw the pop to the other person and that person misses (catching) it it will explode very far because it got shaken up when it was flying threw that air and hit the ground.
1. Throw the pop to the other person.
2. They don't catch it on purpose.
3. Pick up the pop and open it.
4. Measure how far the pop exploded.
5. Record the results.
6. Repeat step 1-5 for every can

Conclusion: The conclusion for small scale test number two is that the Diet Mountain Dew has more pressure/fizz. We know this because Diet Mountain Dew went a record breaking length of all the tests.While the regular Mountain Dew didn't fizz over near as far after being shaken 30 seconds.

Large Scale Test Procedure:
Question: Does tapping on the side/top of a soda can prevent it from exploding?
Materials: Diet Mountain Dew, something to time with (i-pod)
Independent Variable: Kind of Soda
Dependent Varible: If the Soda fizzes over after we drop it and tap it.
Constant Variable: We are going to drop it from the height of olivia's waist.
Hypothesis: If we tap the soda can after we dropped it it will not explode as far if we didn't because the movement and the vibrations of the tap will pop the bubbles.
1. Get Materials
2. Put pop exactly at Olivia's waist.
3. Drop soda can from the height of Olivia's waist.
4. Tap soda can 10 times.
5. Time how long it takes for all the fizz to bubble over.
6. Repeat steps 1-5 for each test.

We know that tapping the can after it has been shook/dropped has no effect on the fizz/exploding of the can. We know this because it took an average of 12.5 seconds for all the fizz to disappear even after we dropped the can and tapped it 10 times.

We have decided that the myth is Busted because even after we tapped the side of the can 10 times after we dropped it, it still took at least 12 seconds for all the bubbles/fizz to pop!
