The hardest part about getting brown is getting a shit with good divergence. Takes a lot of patience with bowel control and the like. If you do it right, your ass can lase at a nice, dark brown color.
Ideally you want a wavelength that is equal parts 405, 650, and 589.
So, we use wavelength summation to get
1/405 + 1/650 + 1/589 = .0057053902
1/.0057053902 = 175.2728498745nm
Obviously, our answer is now in the UV spectrum. But what we must consider is that it is not actually on the same plane as typical light, so what we really have is a set of coordinates for a xyz graph.
The x is 405nm
The y is 650nm
The z is 589nm.
That is to say...it is difficult to put an exact nm measurment on it. In fact, it is simplest to simply take a shit and view it for yourself. But remember, squeeze your asscheeks or you will likely get an undesirable divergence. My record is 1.3mRad if I remember correctly.
Measurements above 2.5mRad will likely cause plumbing damage, so wear safety glasses always!
I'm dyiiiiing:crackup::crackup::crackup::crackup::crackup: omg is this real!!?
Here is my solution: First get you the black/clear laser and call him carl. Then search for a rainbow and throw carl through it. Then go back home and enjoy your brown laser
A fortune brownie (special made brown coloured cookie) transforming (is it really brown? DO NOT question the kid's eye skill, please!) into the little's X-man fan's real life ability (did you have to set my TV on fire:shhh:... next time find another testing object for your "laser eye games")
It doesn't necesarilly has to be a liquefied sh*t, you know:na:
