OK.. so...
But this Extreme Green Laser is being designed especially to deter sharks without hurting them. We have been gradually reducing the power to find that point where it will chase sharks but not be strong enough to hurt them.
and then...
1. Sharks have eyes very similar to humans, with rods, cones, cornea, iris, pupil, lens, and retina.
Scientists believe that sharks see color the same way that we do except, being nocturnal, their eyes are 10 times
more light sensative than ours.
(please note, the spelling mistakes have been left as is...)
Oh yeah, and this...
We have set the power level just below the point where you would need a special license to purchase and use it.
It is also set low enough so as not to injure the sharks.
So, the power is set just below the legal limit before you need a permit - but this is not powerful enough to harm a shark?
A human eye is 1/10th as sensitive as a shark eye, any eye doctor will tell you not to look into even the weakest laser as it will damage your vision. Yet, it wont harm a shark?
So how, exactly, does one gradually reduce the power of a laser to make sure you chase the shark away, yet do not harm it?
Clearly, sharks have developed a method of communicating with humans, and are giving us the big "OK" sign after being flashed in the eye by a green laser. Or, they would, were they blessed with apposable thumbs...
Oh, and this gem:
4. Ask your instructor what color light is most easily seen by the human eye.
It's green.
Actually, it's yellow, but I digress. Perhaps he forgot to mention the underwater part, so I'll let that one fly.
Oh, and just to make it funny....
5. If a green laser is extremely dangerous to the human eye, and it is the most easily transmitted color laser under water, and the eyes of a shark are 10 times more sensitive to green light than a human, and a shark looks directly at its prey while approaching it from as far away as 100 feet, do you think a shark would continue to approach an object it was investigating
People, if you are going to market something, try not to contradict yourselves...
