'Dinosaur-killing' impact did not start global wildfires

I just watched something on Discovery Science;
I was really astonished.

Some machine produced thin air (with among other things drops of water), then some projector projected an image or a picture on that thin air; it looked just like a hologram from one of those Star Trek movies, with one difference; it was real.

You can also move your hand through the picture.

It wasn't of course a hologram, but it was the projection of an image, not on a screen or on a wall or something like that; but in the air (actually on thin air); and you can move your hand through the image.
I find that pretty amazing.

Maybe an an optical virtual image, as we saw in high school physics, but then how could drops of water go on to it?

I'm sorry Austin, I don't exactly know.

All I know is, that in the broadcast, they had this special machine which produced a layer of what they called 'thin air' in the air; this machine did something with drops of water and air to accomplish this; and next some projector projected an image on that layer of thin air.
