Think you could test your theory with a laser pointer?

Like this one? Sigh if you fuckers would stop thinking of really cool experiments I can do, I might be able to get something productive done around here!!!
You know I might have to rig up something...unless you guys think it would be boring and a waste of time. Yeah, you guys are right...nevermind.
By the way, I use this for stargazing and showing kids the stars and constellations. I give great campfire lectures.
I've tied it down and aimed it at a mountain 15 miles away and still spotted the light point through my telescope. I was camping at Joshua Tree National Monument one January during a new moon at 5000' elevation and 18*F and 17% RH...nearly perfect "seeing" conditions. I had a fucking hard-on all night long in pitch black skies looking at perfectly focused images (no wiggly heat waves in the air because of humidity while looking through the eyepiece) of Saturn, rings and moons, Jupiter with the GRS and all moons, Andromeda Galaxy (I jizzed when I could see both galaxies side by side like daytime), Orion Nebula and a few others before I had to pack up before I froze my ass off!!
But I will tell you this. It was so fucking clear, with no moon, and so many stars that I swear I could see shadows on the ground. Gives you something to think about regarding 12/12 lighting huh?
See what happens when all this fun new stuff is happening? I start neglecting other things. Like my top cab. It's been cool for the past week so I've just been running the A/C unit on Fan mode, not realizing that my plenum temp was up to 78*!! 
So I put the AC back into Auto mode @ 72*. Fortunately it only takes 5 minutes to get the plenum back down and the AC cycles off. How cool (pun intended) is that!
However, my top veg cab had been sitting at 91*/26%RH (read from the far right sensor)! Again, All of the towels came out like stiff boards! However after piling in 8 new wet towels and pointing the fan right at them you can see I'm at 43% RH and climbing.
This is the first "after pic". Left is flowering cab near plants. Middle is flowering cab down by water tanks. Right is the veg cab right under the light at plant level.
Here's the pile plus you can see the wet towels hanging from the spigots helping to keep them dark. Multi-purposing!
By the way, the flowering cab is sustaining it's own RH through transpiring plants. No more wet towels in there and remember I'm running 400watts!!

I thought all you guys loved a good stoner experiment. 
Well all I can say is I went ahead and did it anyways.
Here's the setup of the experiment....anybody want to see the results?
Alright as soon as I get 5 "likes" on this post, I'll show you. Otherwise back to work for me!

cool work with the light traps! A lot different than mine and I think they would probably work better for me too! Mine work great for keeping light out, but I'm sure it's a little too restricting on the airflow.
I "liked" it, PM me the details if these other stoners don't get off their ass for ya!!! LOL

We're at two! I see Gumball's and TJP's. But the sad truth, I just went back through the last 3 weeks and I don't have more than 5 regular followers so there will be no ice in 
today. So without further wait, this is my observation and my personal conclusions based on my past knowledge and experience.
First of all I wasn't expecting what I got as a "before" result until I thought about it for a bit. I am working with a true high-power finely focused LASER and the material it is striking is brushed aluminum. The brushed aluminum is not a perfectly smooth surface but rather its "streaked" with hundreds of microscopic ridges and valleys. When the LASER beam is directed onto the brushed aluminum surface it "sprays" light, in hundreds of different angles, confined only to the width of the beam, some of which may re-converge, and the result is a speckled "line" of light.
This picture shows the "line of light" created by 1,000's of split beams, but what's interesting to note is how the line becomes dimmer as it get's closer to the "exit". This tells us that the "average" number of light beams that are escaping becomes significantly reduced. This is the result that oOBe RyeOo was looking for!! Imagine if all surfaces where perfectly smooth, we wouldn't have the beam split and if I were to blow smoke into the same smooth setup we would see 8 individual bounces.
Not only did the flat black paint create the smooth surface, eliminating beam split, just the first reflection sucked away 90% of the intensity.
Here's the exit of the "line of light" on brushed aluminum.
But where's the beam now??
If anybody has a different hypothesis or point of view on what's happening please reply. This is how we used to discuss lab results in Chem and Physics classes in college, and it was fun to hear different observations and theories!

Fuckin' A man. I've re-tiled an entire kitchen counter top so I just happen to have a million of them!
They are rubber so they have a bit of spring. By tightening the screw you can get the right amount of tension that keeps everything aligned. The tape will set everything in place.
Two strips of aluminum tape to join them together and block light from the seam.
Fits perfect!!! Now to wrap tape around to seal it up, then outside for a second coat of paint.
And BAM!! Dry in 1 hour and installed. And it's perfect!!! This is the intake for my cool tube which used to have 2 more 90* bends and wrapped in panda film...and it still glowed.
Time to go build some more!!

glad everything worked out for you. how are temps since the reduction in air flow? I have actually found in my cab if I cover the intake a lot it sometimes lowers temps. I still dont like having my tree canopy totally cover it up, and nothing else will. That and I turned my 120mm fan down on a controller and it lowered temps too.
It's really cool! I feel like a kid in a candy store!
Does it make sense that I replaced 3 ft of ducting and 2 90* elbows (poor man's light trap) with just this? For what I lost with the new light trap, I must have gained back in taking the extra PVC out. Just guessing.

I would have never thought that 2 90s would equal one of these type light vents, And if they are painted black are not 2 90s are not that super-efficient. Thats what I used for my PC cool tube/light trap with the HID.
