True - they work by using microwave radiation.
The sun doesn't have flames coming out of it, but it is an intense source ofelectromagnetic radiation, because of the continuous thermonuclear fusioncontinuously going on in its core.
Most of the radiation emitted by hydrogen flames is in the ultraviolet spectrum, which is invisible to humans. This usually makes the flames colorless, but they sometimes have a very faint blue or purple tint.
There are many different kinds of radiation and the appropriate safety precautions are different for the different kinds. The precautions for using microwave radiation, for example are very different from the precautions for using gamma radiation, or infra red radiation.
Stay away! They launch radiation and flames and intense heat out into space!
The copper flame has a more energetic radiation.
it is easy just flame it
Direct the extinguisher at the base of the flames using a sweeping motion
The flames are not actually mocking the rescue workers - the flames are inhuman and can't mock anything. They are merely personified to be mocking them, meaning that the flames made it harder for the rescue workers to do their work, and the workers felt disheartened and upset, as if the flames had been mocking them.

You can get the blue flames on Halo:Reach by downloading the app on an iPod touch, iPhone or iPad, or you can ask a friend if you don't have one. When you have the app sign in to it using your bungie live ID then you can unlock the blue flames.
Radiation is lethal to Humans, So no.
