Why do Mentos react better with Diet Coke?
After a lot of debate, scientists are now saying that the primary cause of Coke & Mentos geysers is a physical reaction, not a chemical reaction. Their explanation is this process called nucleation. All the carbon dioxide in the soda – all that fizz – is squeezed into the liquid and looking for a way out.
But the combination of Coke Zero & Mentos is particularly potent! Diet Coke and Coke Zero tend to go a bit higher than regular soda, because they have a little more carbonation and the sweeteners help make the reaction a little bigger. Most importantly, Coke Zero and Diet Coke aren't sugary and sticky.
- Use a bottle of Diet Coke. Make sure the soda is at least 85 degree Fahrenheit. Drop seven Mentos into the soda all at the same time.
- First, the act of drinking soda releases quite a bit of the carbonation in it, limiting the possible effect. Second, even if one did get a strong reaction to eating and drinking Mentos and Diet Coke at the same time, you'd likely just quickly vomit up the foam, which there have been numerous recorded instances of.
- Combine the vinegar, water, dish soap and 2 drops of food coloring into the empty soda bottle.
- Use a spoon to mix the baking soda slurry until it is all a liquid.
- Eruption time! … Pour the baking soda slurry into the soda bottle quickly and step back!
Diet sodas produce a bigger reaction than non-diet sodas because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will. You can also increase the effect by adding more surfactants to the soda when you add the Mentos, like adding a mixture of dishwasher soap and water.
- The sweetener in most soda is a mixture of a sugar called "glucose" and another called "fructose". In fact, when these two sugars are attached to each other, it makes another sugar called "sucrose." Sucrose is the regular sugar you use in iced tea or in baking. It is made from carbon, oxygen, and hydrogen atoms.
- Supersaturation is a state of a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances. It can also refer to a vapor of a compound that has a higher (partial) pressure than the vapor pressure of that compound.
- Most escapes in bubbles that form at the sides and bottom of a glass, where microscopic cracks serve as starting points, or nucleation sites, for carbon dioxide to gather. When the carbon dioxide at a nucleation site reaches critical volume, a bubble detaches from the glass and launches itself toward the beer's head.
The last trial I did again Diet Coke's geyser was the highest. It was 11ft tall. It seemed when I added less mentos the height of the geyser was increasing. My hypothesis was correct, Diet Coke was the highest soda to explode.
- Besides water, sugar is the most heavily used ingredient in the Coke mix in terms of volume. One can of Coke contains roughly 35 grams, or 8 teaspoons, of sugar. Coca-Cola is sweetened with pure cane sugar or high-fructose corn syrup, according to where the drink is actually produced.
- Some minerals are valuable due to their use as an important ore or for their use as a gemstone. Some minerals such as the rare Phosphophyllite have become icons in the mineral trade, and are due to their rarity and insatiable demand command outrageous prices.
- Diamonds are minerals: crystalline carbon mineral. Rocks are (usually) made up of many different minerals (or many small fragments of one or several minerals. Diamond is a mineral that occurs most commonly in a rock called 'kimberlite' which is a deep-sourced igneous rock. They also occur in some meteorites.
