Flint Sparks

[xMegaVideos]

Just put a flint in a fire. First it gets red and it glows, then in explodes in sparklerstyle.

[RoadRunnerLaser]

@xMegaVideos - Got a video of you doing it? .... from behind safety glass ?? ;)

[xMegaVideos]

@RoadRunnerLaser No, a few weeks ago a friend of mine did the same and trowed it on the ground. So I thought that would be cool to do. So I made the flint hot, and it startet go glow and I was like; "Cool". But suddenly it explode... and I made a hole in the wooden floor :p So if you try it, try it safe :p Happy silvester :)

[FreakingSuperAwesome]

[925tripson]

Thanks for the video me and my friend loved it we now know how to make sparks and i just got heelys . From, Katlyn ,Gavin;)

[graffbrian1212]

how many mw is that laser?

[RoadRunnerLaser]

@graffbrian1212 Approximately 150mw although the output varies considerably over time. It has been shown (from time to time) to be delivering around 200mw.

Check the video again, I think you'll find that I measured the output on camera.

[naamloos1337]

0:34 looks nasty if you start from that point

[DeathAwaitsYouX]

i do that all the time :D

[1zacster]

cool! not buy a 55lb chunk off ebay and get a sheet of sandpaper XD

[RoadRunnerLaser]

@1zacster

It would be just my luck to have spent hours carefully rubbing down such a chunk into a large pile of dust, only to get slightly over-enthusiastic in my excitement about being nearly finished... and make a stray spark.... Phoooooomph !!!!

[1zacster]

@RoadRunnerLaser lol yeah wouldnt want to be caugh with a bag of 'explosive powder" in your closet during a police raid XD

[Snowbombz]

@RoadRunnerLaser or sneaze.

[RoadRunnerLaser]

@Snowbombz Yes... That's the kind of luck I have... ;(

[dmcpro882]

boringest firework ever....lol 5 stars tho

[RoadRunnerLaser]

@dmcpro882

Thanks for the stars and the chuckle...

My little pile of dust is hardly likely to wow a crowd on Hogmanay, that's for sure... No matter how much they've been drinking !

[nicknoface]

what up with the orange screen???

[RoadRunnerLaser]

I placed laser-goggles in front of my camera to protect it. They filter out green/blue so everything appears pink/orange.

[MrEdsonrap]

se eu quizese fazer faisca eu asendia um bombliu

[nelguitar10]

what lazer did you use and where id you get it

[RoadRunnerLaser]

It's a 532nm DPSS delivering between 150mw and 170mw. I bought it from a friend a few years ago.

[zhzhzh5]

is there also flint in the lighters with just the button???

[KMScarboy]

no its electronic...

[psp10004]

no no and no

[305rocks]

ya ya this video is great!

....or u can take off the cap nd take out the whole lint!

isn't that a good idea...

(sarcasim)

X3

[VideoGamePlayer12]

2:00 dont snort that

[HEATBEARSSOX]

looks like your gonna sniff cocaine

[nicejohncena123]

i just keep rolling my lighter not to hard just ebough so it doesnt spark then after a while i just roll it really fast and it makes good sparks there good enough to hit the ground

[TheTettingZoo]

Just blow the lighter up already xD but still good.

[spawnistight]

flints also come in lighters!

[kanaybid]

thanks for the info

[kanaybid]

how much mw is the laser and is it red or green

[RoadRunnerLaser]

That's a 532nm (green) DPSS delivering around 170mw, if I remember rightly...

The video shows me taking a lasercheck reading, I think you'll find.

The reason the spot looks so orange is because you are seeing the fluorescence from the object subjected to the laser re-emitting lots of energy. The goggles cut out the green, thus the original monochromatic laserlight cannot be seen. The fluorescence is a wider band and the lower portion (orange/red) passes through the goggles.

[blazing1hound]

thats something u should do like wen ur bored like 1 of those days ur just siting at a table and ur realllyy bored its fun lol

[RoadRunnerLaser]

If I remember rightly, I discovered this because I was trying to find a lazy way of cleaning the crap out of the flint-wheel and I thought that a couple of hundred milliwatts of focussed coherent greenness might help. Seeing the little sparks from the flint-wheel spurred me into grinding up a small pile of flint as shown and the little flash brought a satisfied smile to my face. Though first, I had to clean the crud out of the wheel manually. :(

Beware of causing smoking craters !

[way2out2000]

lol nice papers i use that type also lmao!!!!!!

[kenz1031]

does dis really work????

[RoadRunnerLaser]

It works exactly as you see it working on the video. If you impart enough energy into the flint dust it will go up like flash-powder.

If you've got a laser which will deliver around 100mw or more, you can focus it down and try this for yourself. If you get a good focus, you might manage it with less than 100mw.

[PixelEmo]

jolly good show fellor

[4815162342bob]

couldnt u make sparks just by using the lighter? nice though whered u get that laser/

[RoadRunnerLaser]

What ??? Without using the laser you mean ???

Pah...!!! Crazy idea....!!! Gotta use a laser... Gotta use a laser... Gotta use a laser....!!! ;)

To answer your question, someone I know had a few surplus he was selling on eBay. This was one of his units.

[greenaces101]

is that blue laser?

[RoadRunnerLaser]

No. It's a green one (532nm).

[yoshieggz]

Very nice!

[Krauser912]

Lol, nice!

[aliencam]

[coolio319]
