Really really really clever technique. They're essentially firing off a 'strobe' in the form of a laser and then offsetting a really really really fast shutter. Increase the shutter delay by a few picoseconds and fire another strobe. Build up an animation of the propagation of a wave of light!
I often shy away from calling something genius... but this definitely fits the bill.

Their stated objective is almost even cooler than the video of a laser pulse moving through a bottle. They plan to reconstruct a 3D scene based on the propagating 'ripples' from whatever the flash colides with. Wherever the flash collides with an object it'll reflect back in an expanding ripple unless it's really specular or dark. Who would have thought that enhancing something facing away from camera would ever actually be possible. Ingenious!
The Media Lab at the Massachusetts Institute of Technology (MIT) has developed "the ultimate slow-motion camera" is so fast that they can show the propagation of light in slow motion. In English as the "trillion Frames Camera" called this system takes approximately 1 trillion in frames per second.
