I did some experiments with lasers too. I slow down traffic from people who
use radar speed guns don't even have to shine it on the car the radar sensor
picks it up and boy you should see them drivers hit the brakes. I use it as an
extender with a lens i go down 100 yards away from the beam and you can see a
tunnel vision while in the beam. and the video cameras can see the laser beam
but when using the beam in the house ceiling you light up the entire room
when using night scopes. and can exten the beam using it through a lens and
make enormously big house size laser beam.
for those who want to see the laser beam use mirrors facing each other at an
angle or use a fan and go to the edge of the spinning blade and shine it
though not head on but toward the edge of the blades through out the fan from
left to right you will see a beam or sprinklers rain and running water. If i have
more ideas I'll let ya know.

Hey I was just reading your page on cool things to do with a laser pointer.
One thing that you could put up there involves using a shower... Just turn
on the shower on the hottest setting and let it sit for a couple minutes.
Then go back in and close the door really fast. If you turn all the lights
off you can see the beam wicked clear. It is pretty cool and you dont need
any fancy fog machine to do it!

Mount some small first surface mirrors on to the shafts of motors.
Wire
each motor to same battery pack , but different veriable resister.
Mount
the motors on something so they
won't move. Align the motors so that the laser bounces off one, to the
other, to the other
and to a white wall. The more motors you have the better light show
you
get !
Experiment and have fun!
Many of the ideas you listed on your laser activities page work quite
well for
parties, here are also a few I have found to work quite well.
Take the small plastic flash lens out of a cheap camera, they transform
the
beam into a bunch of vertical lines.
Also, you can tape an old laser disk to a woofer you don't want anymore,
and
reflect the laser off of it for something that changes to the beat of
the
music. Depending on the angle, you can get up to five reflected beams.
You can also do much the same thing by taking a small mirror and taping
or
gluing it to the center of a piece of plastic wrap, now put the plastic
wrap
over a coffee can with both ends cut out, or wrap it over the woofer.
It does
much the same thing, sometimes a little more.
Also, you can take a relatively inexpensive two channel radio control
system
for an RC car or such and make a remote controlled xy movement system
for your
laser, this too, works well at parties, especially you want to tinker
with an
old am broadcasting rig and change the FREQ to the receivers setting.
Submit your
own laser feedback.
