Imperfect Perfection
Perfect carbonated drink
Not too fizzy nor too little, hence we defined it as "mid" fizziness
Mid Fizzy
Yup, goes without saying; drinks should be fresh and refreshing!
Refreshing
Additional flavourings to all our taste lovers
Lemon or Orange flavor (or mystery)
Cold drinks will have more carbon dioxide in it, which maintains the fizziness
Cold
Should be healthy to a certain extent, so as to not cause any physical discomfort
Healthy
A slightly sweet aftertaste evokes a pleasant experience (for most of us)
Slightly Sweet
What is a perfect carbonated drink?
Hypothesis
If, in the given location for the production of a perfect carbonated drink, low temperature is present, pressurized C02 is applied to the water, and slight sweetness and naturally refreshing lemon and orange flavors are applied, a perfect carbonated drink is made!
We then picked an experiment featured on Youtube
Picked an experiment
We recorded all the needed materials and steps,
Took notes from the video

01
We researched how we could make C02 in a lab, without the use of burning or any other ways to generate CO2 that would produce harmful chemicals
Finding a suitable experiment to test our hypothesis
The experiment
* for the production of CO2
Beehive Shelf
Diluted HCl *
Opitical Sensor
Delivery Tube
Thistle Funnel
Marble (Calcium Carbonate) *
Round Flask
Stand
Beaker and collecting can
Flavoured Water (Cold)
Material
1. Production
Step 1: Set up the experiment as shown on the rightStep 2:Pour Dilute Hydrochloric acid into the round flask through the thistle funnelThe marble reacts with the acid and effervescent takes place, releasing CO2Step 3:Wait for the gas to go through the delivery tube into the collecting canThe equation is as follows:CaC03(s) + 2HCl(aq) = CaCl2(aq) + H20(l) + CO2(g)
2. Testing
With the use of Opitical Sensors
Step 1:Place the optical sensor next to the container with the carbonated waterStep 2:Wait till the optical sensor processing gets finishedStep 3:If the reading shows 6 - 8 g per liter of CO2, then it is of appropriate valueStep 4: Taste
