Could someone please tell me how this is possible. Although not totally dumb, I'm not very good in the subject of science.

Explain to me how those tiny rolls of sticky paper, otherwise known as fly paper, are packaged. I know they are rolled up tightly and put into a cardboard tube.

How is it that when you unroll them they can unroll and not stick to themselves in a lump. If they are slippery enough to slide to unroll, why do the flies still stick to them? I mean if the flypaper is slippery why don't the flies slide off instead of sticking?

What is that sticky coating made out of anyway? Is it the same thing they use on those mouse and roach motel things? Is it harmful if you touch it? What's the best way to remove it from your fingers? Who came up with the idea for these? Why they like the 2in. wide and 3ft. long? Wouldn't it be easier to catch more flies if they were wider?

I realize this is mundane useless information, but these are just some questions I have.
