Diet explosion mentos soda
This activity is probably best done outside in the middle of an abandoned field or on a huge lawn. But because they are smooth and clean, the activation energy is still relatively high, and the process is slow. The thing that makes soda bubbly is invisible carbon dioxide (CO 2 ), which is pumped into bottles at the bottling factory using lots of pressure. While science teachers have been dropping candies and mints into 2-liter bottles of soda for years in an effort to release all of the dissolved carbon dioxide, the Mentos and Diet Coke reaction became world famous in 2005. MENTOS Diet Coke Geyser - The Original Experiment. Position the bottle on the ground so that it will not tip over. The tubes of candies were threaded onto a pipe cleaner and dropped into the soft drink to create a geyser. When you pull your finger out of the way, all seven Mentos should fall into the bottle at the same time. For additional shipping or quantity options, or to learn more, visit the Mentos Geyser Tube product page. The eruption is caused by a physical reaction, rather than any chemical reaction. Normally, this process is relatively slow, because the activation energy for this process is high. One method for doing this is to roll a piece of paper into a tube just big enough to hold the loose Mentos. From left to right: action of five Mentos candies (per bottle) with Perrier, classic Coke, Sprite and Diet Coke. The answer is a little more complicated than you might think. It is highest for bubbles that form in the liquid itself (homogeneous nucleation), and lower if the bubble forms on some other surface ( heterogeneous nucleation ).
The activation energy for a process like bubble nucleation depends on where the bubble forms. Under these conditions, carbon dioxide begins to precipitate from solution, forming gas bubbles. Other methods include using a large plastic test tube to hold the Mentos or using my Geyser Tube toy invention, which was created to solve this very problem. Launch a Mentos soda geyser 30 feet in the air with the Geyser Tube. At the end of the 1990s the manufacturer of Wintergreen Lifesavers increased the size of the mints and they no longer fit in the mouth of soda bottles. The solution becomes supersaturated with carbon dioxide when the bottle is opened, and the pressure is released. In the 1980s, Wint-O-Green Life Savers were used to create soda geysers. Soda pop is made of sugar or artificial sweetener, flavoring, water, and preservatives. Drop Mentos into a bottle of soda and run away from the 20 foot geyser. Again, the choice of diet over regular soda is purely a preference based on the fact that erupting regular soda becomes a sticky mess to clean up because it contains sugar. The addition of other nucleation sites provides an alternate pathway for the reaction to occur with lower activation energy, much like a catalyst. A roll or box of Mentos chewy mints (stick with the standard mint flavor for now). Carbonated sodas contain elevated levels of carbon dioxide under pressure. When the pressure is released from a soda bottle, the bubbles tend to form on the sides of the bottle. Why do Mentos turn ordinary bottles of diet soda into geysers of fun. The goal is to drop all seven Mentos into the bottle of soda at the same time (which is trickier than you might think).
