    its a bullet shooting through the heat of a flame from a candle

  5. Alec says:

    An image of a bullet passing through a column of hot air generated by a candle. The hot air is less dense than the surrounding air, causing it to refract light slightly differently, and thus appear visible on film. This photo was taken to capture the shock waves generated by the bullet’s supersonic motion.

    how to do that?

    I think it is dynamite that has a bullet going through it and making fire.

    a bullet going through blood

  12. rose says:

    i think this really captures the power of a bullet and the beauty it holds but how we associate it with such a negative aspect of our culture…death.

    This technique is Schlieren photography

  14. carol clark says:

    is it a speeding bullet?

  15. Jay Flitton says:

    I wonder what the Mach number (speed) of the bullet might be?

  16. Fisher Gates says:

    Fire pushing water up and then some shot a bullett through it

  17. Yuni G says:

    It looks like fire! Who made this?

  18. Henry says:

    A bullet going through the heated air above a candle flame.

    It looks like a christmas light in your leg muscle

  20. Kim Vandiver says:

    I took this photo in 1974. The Mach number is approximately 1.03=1/sin(angle between the wake and the shock wave). The hot air and the shock waves are made visible by a technique called schlieren. 1/3rd micro-second exposure on ASA 160 Ektachrome film.
