Hello, I have a few questions and i hope you will help me to find solutions.I am in the middle of writting the thesis about leidenfrost effect which is well known and featured, beacause of its attractiveness. But the problem is, I am supposed to describe these stars or stars imitating shapes of water and i cannot find this kind of phenomenon anywhere. I wish I known when it happens or what is needed at least. It looks to me like noone wants to describe it. I am stuck. Can u help me?
It's the visual equivalent of popping bubble wrap. :-)
I love you site - this is great stuff. hey could you try melting some plastic bags with that lens? I want to melt some plastic with solar power and the Fresnel is appealing method
Great footage, a brief explanation of the science behind it would really add to the video though.
Man, I'd stay well away from something like that to protect eyes and skin; what's the UV concentrations like?
my friend how mush is mirror
Is it a new camera? Looks great and thanks for putting out more videos lately!
Firefighters equivalent to the soldier's marching to the sound of the guns. Thanks.
Thanks for the cool footage!
we needed music for this
how hot can you actually go with these lenses? and cant you set 2 focal points of 2 different lenses to make it twice as hot?
Dan, have you published any books of your own?
Hey Dan do you sell the focused lenses without a frame?
That was cool!
For those who don't know: The Leidenfrost effect is a physical phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly. Due to this ‘repulsive force,’ the droplet hovers over the surface rather than making physical contact with it. https://en.wikipedia.org/wiki/Leidenfrost_effect
It looks like clear Flubber
whats that garbage in there? what did you mix in
Very neat footage! What were the other liquids?
Thanks! Glad to see some new videos. You guys are awesome!
