What is that spray stuff they use in shows like "Food Network Challenge"?

Question

You know that stuff they spray when they are making sugar sculptures to join the ends or something? It comes in a white can and it looks like those cans of compressed air with the little straw attached to it.

Answer 1

It is liquid nitrogen.  It is used to cool the candy down at a rapid rate so the candy sticks together.

Answer 2

I always thought it was the stuff that you use to clean your keyboard and stuff like that. I thought it was just to dry it? I am curious about this myself now.

Answer 3

it could be like a sugar/water spray that stick the sculptures together or makes it shiny and fresh:)
