Fox News: Special Report!

In recent weeks, a video of a couple guys adding Mentos mints to Diet Coke has been circulating the internet. (View Here) Today, the hilarity was taken to a whole new level when Fox News called the chemistry department here at UCLA to do a special report on the dangers of drinking diet coke while eating mentos. (i.e. Can it make a person explode or do internal damage??? lol) Here's a spoof of this on the web. (View Here) After circulating around the department a bit, Steve and Cari jumped at the chance to do a demo on air or the mentos/diet coke experiment and educate the ditzy blond reporter.
So why does Diet Coke explode when Mentos are added?
It's simply a matter of surface area. Mentos have a very high surface roughness (or are "rugged" as described by the reporter) and this roughness serves as nucleation sites for the dissolved CO2 in the Diet Coke.

Here's a run down of the filming:

Steve confusing the heck out of the reporter with his dumped down scientific explination. She just wasn't going to get it, no matter what.

Filming more explinations by Steve.

Ognjen, Cari and Steve preparing the Mentos for addition to the Diet Coke while looking spiffy in their lab coats and CNSI goggles.

Explosion #1: 2 L of Diet Coke + 5 Mentos (the camera guy was too busy running from the soda to capture the explosion so they had to do it again)




The peanut gallery.




Explosion #2: 2L Diet Coke + 8 Mentos

The GRAND Finale: Steve drilled a small hole in the top of the bottle to act as a nozzle so the soda would spray higher. It shot ~ 15 feet in the air.



Cari filming the final wrap up.


So, if you're in the LA area be sure to tune into Fox News tonight at 10 PM! :)

Hi! Might want to check out Suzanne's bridal on Gilbert/Guadelupe in Gilbert. She is very helpful, and can design a dress you are looking for/at if she cant get it. :)

Hope that helps! Good luck!
