Ep 13. Nucleation Fountain

In Science Max season 3 episode 13, titled "Nucleation Fountain," the host Phil becomes interested in creating a "fountain" using carbon dioxide and water. Phil begins by explaining the concept of nucleation, which is the process of creating small bubbles in a liquid. The more nucleation sites, the more bubbles are formed, creating the effect of a fountain.

To demonstrate this concept, Phil creates a nucleation site by dropping a Mentos candy into a bottle of diet soda. The carbon dioxide in the soda adheres to the rough surface of the candy, creating a rapid release of gas and causing a geyser-like reaction. Phil then explains that the fountain is similar to a geyser in that it is caused by a build-up of pressure.

Phil decides to test a variety of different nucleation sites to see which ones will create the most impressive fountain. He tries sugar, salt, baking soda, and even milk. Each substance creates a different effect; for example, the milk creates a slow and steady stream of bubbles, while the salt creates a quick and explosive reaction.

Next, Phil decides to build a nucleation fountain using water and dry ice. He creates a large container and fills it with water, leaving a gap at the top of the container for the dry ice. Once the dry ice is added, it begins to sublimate, or turn from a solid to a gas. This creates a build-up of pressure and causes the water to shoot out of the container like a fountain.

Phil also tries adding different substances to the water to see how it affects the fountain. He adds soap, which creates a frothy and colorful effect, and food coloring, which adds a pop of color to the otherwise clear water. He even adds glitter for a fun and festive touch.

Throughout the episode, Phil emphasizes the importance of safety when conducting these experiments. He wears gloves and goggles when handling chemicals, and he uses a large container to ensure that the fountain does not spill over or cause any harm.

The episode wraps up with a recap of the different nucleation sites and their effects on the fountain. Phil shares a few tips for viewers who might want to try this experiment at home, including wearing proper safety gear and conducting the experiment outdoors or in a well-ventilated area.

Overall, "Nucleation Fountain" is an entertaining and interactive episode that teaches viewers about the science of nucleation and pressure. Phil's enthusiasm and sense of humor make the material accessible and engaging for viewers of all ages, and the colorful and explosive fountain is sure to leave a lasting impression.
