Instant Freeze Soda
For this experiment my partner ,Griffin, and I were inspired to recreate a experiment we saw on youtube. The experiment was basically putting a coca cola bottle into a freezer for a good amount of time. The purpose of our experiment was to make a coca cola slushie.
The scientific Method
Question: Will the soda turn into a slushie even though we have no idea the temperature of the freezer?
Hypothesis: If the soda is placed in the freezer for enough time, then nucleation is possible.
Materials: Coca Cola 500ml, Freezer(-24 degrees celsius), and Sunkist 500ml.
Experiment steps:
1. Grab soda and shake violently so pressure can build on the top of the bottle.
2. Then place in the freezer for 3hr 15min.
3. After 3hr 15min grab the soda and release the pressure and turn it upside down.
Experience:
At first I thought our experiment was going to be a fail, which it was for a moment. Since we knew for sure that coca cola would instantly freeze. We tried it with a 500 ML sunkist to see if it works with other sodas. Griffin and I came in during lunch to see if the sodas were ready. It was around 2hr and 40 and since we didn’t have any idea how cold the freezer was we just assumed it was colder than what it had to be. We grab the sunkist out of the freezer and followed the steps. The sunkist do not turn into a slushie because it wasn’t cold enough yet. Since we open the sunkist we had to shake it violently again so pressure can build to the top then place it in the freezer again. Once class started we needed a couple of more minutes till the coca cola was ready. We grabbed some cups to pour the coca cola when it slushes. As we opened the coca cola, coke just started spilling for some reason so we walked towards the sink. The coke wasn’t reacting so we closed it and turn it upside down. One second later we just start seeing the coke crystallize before our eyes.
Science Behind It:
As you might remember I wrote previously wrote that I shook the soda violently. The reason why we shook it violently was because we wanted pressure to build up in the bottle. Creating this pressure in the bottle actually helps by decreasing the freezing point of the soda. If creating this pressure, lowers the freezing point I wonder how long would it take for the soda that doesn't have pressure built to reach the same point as the one that does? Once we grab the bottle out of the freezer you noticed we opened the bottle so the pressure built up can escape. If we didn’t do this then the coke will start shooting out slushie coke. After that we twist the cap back on, then turned it upside down. Turning the bottle upside down helped trigger the nucleation. Nucleation is when a phase of matter is in the process of transforming into its next phase, but needs that push.
