Light travels fast. Very fast. So much so, that it just seems instant to us. But, for the first time ever, we can see for ourselves that it isn’t and that it does indeed travel.

Researchers at the Heriot-Watt University in Edinburgh have managed to capture a laser beam travelling through the air for the first time. In the video bellow, which was recorded at 20 billion frames per second and lasts 6 nanoseconds, we see the laser beam coasting through the air, with the protons of the beam reflecting off particles in the atmosphere.

    A bellows or pair of bellows is a device constructed to furnish a strong blast of air.
    The simplest type consists of a flexible bag comprising a pair of rigid
    boards with handles joined by flexible leather sides enclosing an
    approximately airtight cavity which can be expanded and contracted by
    operating the handles, and fitted with a valve
    allowing air to fill the cavity when expanded, and with a tube through
    which the air is forced out in a stream when the cavity is compressed.[1] It has many applications, in particular blowing on a fire to supply it with air.
