Bright flashlight the emits white light

[cragar]

I have a little prism and I have a bright flashlight the emits white light
and when I shine the flash light into the prism it does not break it up into the colors of the rainbow , any suggestions , I have tried from all angles .

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.
