I have half a brain and have done the research, I would like to see your video!
Also, I never knew a laser bounced off a solid object (at a distance that was actualy viable to call it bouncing), the object may refract/splay the particles of the light, but bounce a full reflection off a solid object? (mirrors dont count)

Give these a read...

If every person on Earth aimed a laser pointer at the Moon at the same time, would it change color?

Even as a big group attempt it would be very difficult to produce a visible result.

The dot need not be brighter than the suns reflection: you'd attempt a thing like this on the dark side of the moon, ideally in a new-moon night so that you dont get blinded by the lit side.

In theory, it would work provided you used enough lasers... even if you hit just the surface and it scatters off randomly from there (not using the retroreflectors). The question remains: how many lasers would it take?

Sigar-box math:

- it would take at least several watt/m2 over a large area to be visible on the new moon.

- 1 mrad divergence laser, would light a circular area with 400 km diameter (!), which is a good portion of the size of the lunar surface facing us (its diameter is ca 3500 km).

- a 400 km diameter circle has a surface of 125.000 km2, or 125 billion m2.

- to light this area up with 10 w/m2, it would take 125 trillion watts of laser power

- 625 trillion dilda's would make it possible, provided every person on earth would be able to point 100.000 dilda's at the same area of the moon simultaniously.

Sigar-box conclusion:
It will not work unless we invest all of the earths resources into producing dilda's and batteries, and breed a lot more people to point them ;p
