what the heck! you guys forgot vaseline glass! known as uranium glass too! like a damn chunk of kryptonite..
remember to use your uv-blocking yellow glasses when watching for fluorescence. not only to protect your eyes - its a whole different world. shining a blu-ray at green plant material, its boring. but with glasses, chlorophyll shines red, you can clearly see what parts have how much chlorophyll, its really fascinating (although its hard to describe).
Just found the most UV bright material from my stock so far. It's Irwin strait-line orange chalk powder. It is like an orange arc-weld from ~30 feet with my 200mw GGW.
Don't know about laundry agent for sure, but about paper, it's fluorescent part for the natural fibers (like cotton fabric), and part for the "whitening" used in the making process ..... sorry, i don't think that bright white things are "invisible" in daylight, anyway :d
well, (some sort of) tissuepaper dont fluorescene, recycled paper neither, and envelope-paper neither.. sure, most of that stuff is brown/grey, but if it was the natural fiber, it should fluorescene at least a bit..
oh, another good one: chestnut-tree! you put a small branch (branch? a small one, a centimeter diameter is plenty!) into a glass of water, shine 405nm at it, and see a bright white-blue fluorescening liquid coming out of it and mixing with the water! its invisible in daylight, and shines impressively strong!
heh! "funny" thing, at the german east-sea coast, amber can be found. unfortunately, wwII ammunition was dumped after the war, which in the decades decomposed. so there are now places where a white phosphor mixture from self-igniting ammunition is washed at the coast. and, hooray, you cant easily distinguish it from amber! (almost) same density, same look, same hardness. the only difference is that it will ignite after a few minutes in your pocket. forming high-temperature, sticky burning goo, which sticks to your hand and everything. cant be turned off easily. when you jump into the water its off, go out again (with nasty burns), it will ignite again. really horrible stuff!
why i tell this totally off-topic scary shit? because amber happens to brightly fluorescence! ;-)
i tried to find amber at night with a blu-ray laser (defocused) and blu-blocking glasses, but nada. sure, it was summer (water too warm and not dense enough), it was the northern sea, and there are tourists everywhere..
will try again in winter!
i just love that idea! combining lasers with "searching treasures" and minerals! *happy*
^ but if you don't want to risk your laser (salty water and all the rest), you can also use one of those pocket-size UV tubes, battery operated, like as example these ones, or similars.
it's not funny at the same as with a laser, but it works
are you kiddin? no laser, but a stinky uv tube?
seriously, its not really stormy at the moment, in summer. besides, my laser has a window in front of the lens. its not waterproof, but surely weatherproof.. will post some pictures when i'm home again!
When I mentioned Fabreeze I was talking about shooting the laser into the spray bottle. The fluid lights up although it could jsut be refraction or something.
Heres mine- All scorpions glow- the biggest -the Emperor shines a beautiful torquiose- scorpion hunters use a small handheld blacklight. Antifreeze too- and styrofoam-other 'bodily' fluids(uck)-luminoil of course-plus a no longer sold brand of eyedrops- Murine AC IIRC- found this out by accident when using the drops(now why would I be using them??) at an after-hours club that had a ton of blklights. NOBODY wanted to look me in the eyes. lol=<(*u*)> hak edit:I guess luminoil(luminol not sure of the spelling)only reacts after mixing with certain fluids.-I stand corrected
