Soft drink experiment
By Cassidy Abbot

Method
Experiment 1:
1. Get 3 pairs of soft drinks
2. Get some scales
3. Weigh each pair against each other
4. What happens?

Experiment 2:
1. Get 3 pairs of soft drinks
2. Get a tub of water
3. Put each pair into the tub
4. Which floats? Which sinks?

Results
Weighing: COKE vs. COKE ZERO= Coke is heaviest! SPRITE vs. SPRITE ZERO= Sprite is heaviest! PEPSI vs. PEPSI MAX KICK NO SUGAR= Pepsi is heaviest!
Floating: Coke: Sinks, Diet coke: Floats, Sprite: Floats, Sprite zero: Floats, Pepsi: Sinks, Pepsi Max Kick No Sugar: Floats.
My observation

The diet/zero drinks weighed lighter on dad’s scales and also floated in the water. The standard drinks were heavier and they sank.

The main difference between the standard and diet drinks is that the diet drinks use sweeteners instead of normal sugars. These sweeteners are aspartame & acesulphame potassium. The diet drinks also contain phenylalanine which is an essential amino acid. The diet drinks also contain a small amount of protein and more sodium.

My observation is that the standard drinks are heavier than diet drinks and they have more sugar so the sugar is making them sink because sugar is heavier than artificial sweeteners.




Introduction
This project is about testing the weight of soft drinks. I have got to weigh a can of Coke against a can of Diet coke and see which is heavier. I can also weigh other soft drinks (PEPSI vs. PEPSI MAX KICK NO SUGAR, SPRITE vs.SPRITE ZERO). Another experiment is putting the two cans in a container full of water and watch what happens.
I hypothesise that Diet coke will be lighter than coke, sprite will be heavier than sprite zero, and pepsi will be lighter than pepsi max kick no sugar. I also hypothesise that the standard drinks will sink and the diets will float.
Hypothesis
Materials
Scales
Tub of water
Pepsi
Pepsi max kick no sugar
Sprite
Sprite zero
Coke
Diet coke
The main difference between the standard and diet drinks is that the diet drinks use sweeteners instead of normal sugars. These sweeteners are aspartame & acesulphame potassium. The diet drinks also contain phenylalanine (check this) which is an essential amino acid (Cassidy to check this). The diet drinks also contain a small amount of protein and more sodium (check is this salt).

My observation is that the standard drinks are heavier than diet drinks and they have more sugar so the sugar is making them sink because sugar is heavier than artificial sweeteners.


Xtra for experts
How did diet drinks come about:
Diet drinks were originally invented for diabetics, athletes, and people who want to reduce their sugar intake or lose weight. Diabetics get sick if they have any sugar. People who want to lose weight don’t want all the calories in sugar.

Conclusion
In conclusion, I have learnt that diet drinks are lighter than standard drinks because they have sugar substitutes in them. Websites I have visited and people I have talked to say that diet drinks are bad for you because of those sugar substitutes (Aspartame and Acesulphame Potassium) Therefore, I am not going to have diet drinks.I have found out that more people prefer standard drinks as well. This experiment has changed the way I see soft drinks forever.
THNX FOR WATCHING!!!!!!!
Public opinions
See my videos
Diet soda started when a man calked Kirsch Bottling released ‘No-Cal’, a sugar free ginger ale. Then, Royal Crown Cola created ‘Diet Rite’, a diet version of ‘Rite’. In 1962, ‘Dr. Pepper’ released a diet version; ‘Diet Dr. Pepper’. After that, the Coca Cola Company joined the market with ‘Tab’, a diet drink sweetened with cyclamates and saccharin.
These were the only drinks on the market until PepsiCo released ‘Diet Pepsi’. Following that, ‘Diet 7 up’ and ‘Diet Coca Cola’ were released. Also, flavors like lemon and vanilla were added to soft drinks. In the mid 80’s, alcoholic diet drinks came out as well. Today, sweeteners are Aspartame and Acesulphame Potassium.
