    I have the same problem, my prism still kinda sucks by try intensifying the amount of light you put in, also turn out all the lights accept the one your using.

    I finally got it to work I had to hold it at a weird angle and it defiantly was not the angle
    that hey showed in the instructions.

    Try confining the incident ray to a narrow beam by use of a slit.The angle does make a difference so mess around with it and enjoy it.
