Cut through the clutter and receive in-depth analysis of relevant news. I had not at that point thrown up in about 15 years, so this was bizarre. Qrius delivers fresh, immersive writing that answers the question ‘Why should I care? Keep in mind, though, that it is probably wise to do this experiment outside if you want to stay dry. A Mentos candy feels smooth to the touch, but place it under a microscope, and the surface looks rougher than sandpaper. What do you notice from the videos? It seems a bit strange for there to be such an extreme pressure change, enough to explode a bottle. Ultimately, the pressure became too much and I threw up a ton of foam red, like the multivitamin coating. Because Mentos candies are rather dense, they sink rapidly through the liquid, causing a fast, large eruption.

Instead, the vigour of the jets depends on various factors that affect the growth rate of carbon dioxide bubbles. The health benefits of sunlight: Can vitamin D help beat covid? Featured articles 1. This is another reason Mentos works so much better than other similar confectioneries. This theory, suggested by “Mythbusters,” was confirmed by Tonya Coffey, a physicist at Appalachian State University, and published in the American Journal of Physics in So let that be a lesson to you. Based in Massachusetts, he blogs about cycling at MaxTheCyclist. If you videotaped the reactions, you can watch your videos now. As the candy sinks, it passes through more soda and creates more bubbles.

In non-sciency terms, basically, this porous surface creates a lot of bubble growth sites, allowing the carbon dioxide bubbles to rapidly form on the surface of the Mentos. The buoyancy of the bubbles and their growth in size will quickly cause the bubbles to leave the nucleation site and rise to the surface of the soda. Bubbles will continue to form on the porous surface and the process will repeat, creating a nice foamy result. You can also increase the effect by adding more surfactants to the soda before you add the Mentos, like adding a mixture of dishwasher soap and water. Another factor contributing to the size of the geyser is how rapidly the object causing the foaming sinks in the soda. This is another reason Mentos works so much better than other similar confectioneries. Mentos are fairly dense objects and so tend to sink rapidly in the liquid. The higher the temperature, the bigger the geyser due to gases being less soluble in liquids with a higher temperature.
