You have your choice! Pick one (or two... or all 3) of these questions to thunk about.
It's too early this morning, and I have a migrane, so I went to the "evil internet" for my answers....
If nothing sticks to Teflon, how do they stick Teflon to the pan?
First they sandblast the pan to create a lot of microscratches on its surface. Then they spray on a coat of Teflon primer. This primer, like most primers, is thin, enabling it to flow into the the micro-scratches. The primed surface is then baked at high heat, causing the Teflon to solidify and get a reasonably secure mechanical grip. Next you spray on a finish coat and bake that. (The Teflon finish coat will stick to the Teflon primer coat just fine.) Works a lot better than the early Teflon pans, but you can still ruin Teflon cookware by subjecting it to extremely high heat. This causes the bonds between some of the carbon atoms to break, giving other undesirable stuff a chance to bond thereto (courtesy of The Straight Dope)
How do they get a deer to cross at that yellow road sign?
Firstly Deer Urine is used on the sign, and across the road, also.. because all deer are unfortunately lacking in any formal education, they are unable to read. Thus, the picture.So, a deer approaches sniffs, thinks "hey, who peed all over the place and stuck a picture of me in the middle of it, I am going to get to the bottom of this, they ain't pinning this on me"then he crosses (courtesy of Yahoo Answers UK)
Why do they sterilize the needles for lethal injections?
There is an unwritten law that if the condemned prisoner lives through execution they get pardoned. The reason why the sterilize the needle is in the rare case that it does happen and he/she gets an infection from it they can sue the state. Sounds odd but true. (courtesy of Yahoo Answers)
