What Could You Do With 120 Laser Pointers?

Posted by Cliff on from the special-effects-anyone dept.

lazed-dazed asks: "I've recently come into possession of a large number (120 of 'em) of keychain laser pointers (minus the fancy diffraction adapters, though the specs are the same). So, Slashdot, I ask you: Can you give me any project ideas for these low-wattage bad boys? Holograms? Fancy cigarette lighters? Laser cannons? The crazier, the better! Oh, and don't bother suggesting cat toys."

    If you point all of them at piece of solder, will it melt? If you point all of them at a match will it ignite?

    No, better yet, Bush's next public speaking engagement. Imagine the surprise he'd get when suddenly 120 lasers all point at him(and the fun I'd have watching him dive for it :)

    Having every protester bring a laser pointer and point it at the source of their ire as they go past could make the point quite well

    Yeah, great idea, get yourself shot.

    What's invisible light? I usually find that when I look into a light source that it's highly visible.

    Think I might go and patent the above, but using plain old visible light instead :-)

    ...for a few bucks each, and have a few hundred bucks with which to buy a nice quad-proc motherboard and CPUs.
