My friend reckons he's getting a lightsaber

Why does the laser seem to just end after a measly half a mile? On flat land, the horizon gets in the way at 7km's so if its true, the light should go on for a much longer distance

Most amazing jew boots

Even if you could make that thing into a lightsabre it would only be the size of a letter opener.

This thing is sticky, and I don't like it. I don't appreciate it.

Anyone hear anything like this? He swears he saw it on the internet somewhere and placed an order...

Lets analyse what has been told.

1) Your friend is getting a lightsaber
2) It can go for 120 miles
3) It shoots down airplanes
4) It easily burns stuff
5) Burns your eye at a certain angle.

Dude, does that make sense to you? lol

With Wicked Lasers, the choice is yours: either a unique red laser, an extreme green laser, or a mesmerizing blue laser can be used for pointing to stars and constellations.

Totally makes me wish I had $1000 to spend on a laser to point at stars.

I was speaking idiomatically.

I've never taken a class in astronomy, but I'm pretty sure that you can use them as a pointer outside when not projecting onto a solid object. If there's enough moisture/stuff in the atmosphere it'll scatter off all the random particles (think how you can see the path of a movie projector's light because it scatters off the dust in the air) and make it visible in all directions.

What kind of toxic man-thing is happening now?

In a Vacuum, it'll go on forever. But Earth (thankfully) does not have a vacuum on its surface. As such, the light will be scattered by particles in the atmosphere. This effect becomes much more extreme as distances increase.
