We BROKE the WORLD RECORD for the Largest Soda Mentos Geyser!!!!!
We could not have done this without the help of the LACI (Los Angeles Clean Tech Incubator). They are currently running an IndieGoGo to sell memberships. If you are in the LA area or would like to sponsor a membership please go to this link:
Mentos on the surface look very smooth however at microscopic level they tons of mini little crevasses (like peaks and valleys) and its in these little areas that are know as nucleation sites. They trap little tiny pockets of air, and when the dissolved CO2 hits these nucleation sites it forms a bubble. The bubbles grow with additional C02 dissolving into them until they are buoyant enough to rise to the top of the container. If we add enough Mentos, we will get A LOT of CO2 bubbles forming, so many in fact that it will turn to what we call a foam fountain. AND if we have a system that creates pressure of this foam we can direct it and send it easily over 5 meters or roughly 16 feet. And that’s exactly what we did!
Here are the specs for how we broke the record.
-About 20 L of soda (Diet Coke… research on the internet suggests this is the best due to high C02 levels and the aspartame working as a surfactant, weakening surface tension and allowing the fizz to break free faster)
-9 packs of Mentos
-Carbonating the soda with cold soda to get as much CO2 dissolved as possible
-Used a poly carbonate 5 gallon water jug
-Created a Mentos dropping devise with a 3D printer to easily drop Mentos, redirect the soda stream, and maximize pressure.

AWESOME! We attempted to do this on a much smaller scale for my 7 yr old who LOVES science and failed miserably on the first, second and third attempts.😢
Finally, on the fourth it worked and she was thrilled!😊 Which only encouraged her to want to do more experiments. So her older brother 23 and sister 20 decided to show her the vinegar and baking soda trick. She loved that one also but, once again she wanted more! Unfortunately, we were all out of everything and we had to put an end to her day of science experiments.😣
However, your channel gives her and I new ideas all the time, so thank you for your time and love of science!!!!
Nick Uhas, you have single handedly distracted me, for 3 hours, from studying for my Board of Certification exam to become a Medical Lab Technician, and I'm not even mad, you make science even more enjoyable (didn't think that was possible). keep it up:)
Nick Uhas thanks! :) I hope to become a Medical Scientist in a little over a year. I don't believe I'll be allowed to expirament in a clinical setting 😛 so that makes your videos that much more enjoyable.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
