Even if gravitational pull concepts go over your head, this video is pretty mesmerizing. (The enchanting background song by Camille Saint-Saëns may have something to do with it too.) Under normal gravity conditions, Diet Coke bubbles form around Mentos and rise up through the soda to create a powerful stream of bubbles, with lots of soda touching the candy. 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.

Not a big fan of fighting games? Try Mentos's Kissfight styled after a head-to-head fighting game where you, as Nicky 'Fresh Lips,' must out-kiss your female opponents rather than beat them up. Collect falling Mentos candies for super-charged kissing power. Just like in real life! At least, that's what they want you to believe.

Rough surface: One of the reasons why Mentos, magnified here, are fountain-makers.
What really makes Mentos and Diet Coke form those fizzy fountains we love to watch on YouTube? 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.

The UK's Telegraph has a good set of pictures from the record-breaking set of simultaneous explosions of Diet Coke and Mentos in Leuven, Belgium. Or as it's known in Belgium: Coca Cola Light. Several videos of the event have appeared online - the best we could find are after the jump.
