I would have never believed you would be able to concentrate a flashlight to the point it would burn anything...that was really cool. You make the best video's ever! I think my kids learn more from your video's than they ever learn at school...

HIV spotlight... Uh oh... :U

not sure what your talking about with fake videos... my torch flashlight starts paper on fire in seconds
thats the only reason i bought it

remove the class of that Vector POB and clean it carefully, as you can see it's now a bit smokey. You'll have more output.

ordinary glass is practically opaque to IR

@Quillrun ; Because this is greenpower~science aparently

"Sawdur stuff" ?

WWWOOOWW I never seen this before thanx for sharing keep the videos coming!!
GOOD JOB!

From a fan...

i just break the glass and put dry leaves in it....
Your explanation is probably wrong. It's NOT the light you are focussing which starts to heat and burn the materials. It is probably the INFRA RED frequency which you are (also) focussing. This is why the laser does not burn, because it has just visible light not the infra red (it's probably laser light from a semiconductor laser). The flash light has a halogen or tungsten bulb which creates lots of infra red and only a little light.

Infra Red is not reflected good from acrylic mirrors.

Why not cross the battery terminals with steel wool and start the fire with less hassle.

Is it possible to further intensify the beam of light by reflecting the light from the parabolic mirror through a magnifying glass?

Each object filters some light and the focal points would be all wrong. When light passes through or is reflected off an object, roughly 10%-20% is absorbed, So mag glass 90% output to the cry bal 90% x .9 =81% out to parabolic 81% in x.9 = 73% out. at lest 27% drop in power. You cannot amplify light, just concentrate it with lenses.
