In Videos: Diet Coke and Mentos in Zero Gravity

Even if gravitational pull concepts go over your head, this video is pretty mesmerizing. (The enchanting background song by Camille Saint-Saƫns may have something to do with it too.)

However, in microgravity, there is no "up." Bubbles that form just stay near the Mento and inhibit more cola from touching it. It's nice to know that a team of scientists are working on "Menticular" effects on soda pop in space. Watch the video after the jump.... More

Until recently, explanations were mere conjecture. But a physicist at Appalachian State University in North Carolina set her students on the trail. What they found: Diet Coke works best, even though other fizzy liquids were tested Caffeine does not accelerate the reaction, as had been theorized It is not a simple acid-base reaction, as had also been speculated What's happening, said the physicist, Tonya Coffey, is that Mentos are an ideal shape, texture, and weight to encourage carbon dioxide bubbles to form in the Diet Coke bottles....
