Found the trucks ones funny, the driver has no chance of survival. Might as well get speedy bricklayers to build a wall in the road. :p

Fifth force? I will watch that video next, came to post this. Could be of interest to members just to see how bright a low power laser pointer is at a distance.

That is not a 5w laser, maybe a 1.5w and this guy is missing the fact that the source of the laser is not it's output at that Gatling units output lens but the facet at the p/n junction of the laser diode inside, you actually can't focus a laser to an infinity small point.

The limit of the focus of a laser is its wavelength. One cannot focus it smaller than that. So, taking a 450nm laser one couldn't focus it to a point smaller than 450nm.
