Nucleation of Water

Conclusions
The purpose of this experiment was to examine the nucleation of supercooled water and possibly get media of that and superheated water. Unfortunately, I didn’t really get to do much of either with my experiments. I know now that I was most likely trying to supercool the water at a temperature that was too cool for my set up. If I were to do this experiment again I would test the samples at temperatures ranging from -3 C to -16 Celsius because it seems even at these temperatures some bottled waters can experience super cooling nucleation effects as seen on youtube.com. From the video i have of superheating water, I let it warm the microwave for 4 minutes when i took it out it was just slightly boilking but as you saw when i put hot cocoa powder in it, it created many nucleationsite to where it looked like it furiously unleashed its power. As for the Supercooling media, I wished it would have shown better. I used Bottled fiji water and the first I cooled to around -3 celsius. the second time i did it i cooled the water to about - 4.8 and had better results.
