Combining Mentos and Diet Coke may be nothing new, but rarely do we get the chance to see it captured at 1200fps, unless you have the Casio EX-F1 that is. Video after the break.

Woodhead compensated for the 1200fps' paltry 336x96 frame size by stitching four different Mentos tests together, and the results are awesome. Globs, ribbons and rings of Coke that are impossible to track in real time come to life when seen in slow-motion

You won't be seeing this in stores anytime soon, as it was built for just demonstration purposes. Click here for first picture in gallery. Here's how it works:
