Easy/Creative/New Way to see your beam!

[davidgdg]

Don't wash your hair for a week, shake your head and then shine the beam through the resulting dandruff cloud.

umm, you might want to take into consideration that a good percentage of the couch and bed "dust" is not actually dust but is in all actuality skin. While workin for Kirby as a demonstrator it was our job to vaccuum someones bed or couch to show all the "dander" we could pick up. This one lady had a sheep skin bed mat and I pulled up 3" no i'm not kidding 3" of skin

If I remember well, in a lifetime a mattress can accumulate 1 pound of dead skin.

I could be even worst if it wasn't for those tiny bugs who fead on dead skin (how do you call those again?).

Mmmhhh... i would be worried about dust and dead skin falling into the laser lens and affecting its performance... and even worse on hi-power units, creating a surface "hot spot" that could permanently damage its outer coating...

Even the smoke from a top notch industrial smoke machines will eventually leave an oily, slippery film on everything over a period of time. Cigarette smoke is even deadlier to electronics and optics... ugh!

That's why I regularly look with a magnifier at the lens (laser off of course) to see if there's grime or dust on the lens. Acrylic lens are even more sensitive because they can be scrached very easily with small dust particles.

Mites. They live in and off your dead skin, and tiny ones even live at the base of your eyelashes!

Ok, so now we're using dust mites and their environment as a means to see laser beams. Hmm..

Oops, here comes PETA! I wonder how many poor little mites we cook?

Hey that might make some fun macro photography! Beam divergence test: See if you can pick these guys off, one at a time.

LOL

It's incredible that "complex" live forms can live at that scale.

They are so tiny, but still multicellular.

I find that quite amazing.

This method works much better if you have asthma.

I like the picture of the "mite army".

That looks more like a photoshop copy paste. They all look the same.

Seriously, just set the laser down and around ten feet away (if you can) spray some deoderant into the path of the beam...

 

[Drivinfast247]

Im sure its been mentioned here before but you can use canned air. Just spray it upside down and it will make your beam visible. But be careful because the liquid/gas will freeze whatever it comes in contact with.

PS. I know this isnt free but its still a way to see some beamage.

Canned air?


Never saw that at my local supermarket....

So, now you need:

1. safety goggles AND
2. surgical mask (for breathing)

lol

I was subbing for a class once, so I did this with chalkboard erasers. It was epic.

This is the stuff teens in school (like me) need to be learning about!
