Scary Research When You're a Writer

Do all writers research? Does it ever scare you? 

Normal days research;

• How long will a walk in freezer stay cold if the electricity goes out. 
• How do you ventilate a bomb shelter
• How long does it take to dance-walk five miles
• List of Federal prisons in Virginia
• Amount of a prison sentence for armed robbery
• Types of guns police use
• How many tanks of air do you need to stay underwater for two days
• Effects of staying underwater for two days
• Look up stencil for putting peacock feathers on my car

Those were just a few from last week. Except the last one. I think I want to put vinyl peacock feathers in bright colors on the hood of my car cause the paint has some pits in it. :)

In my current WIP I needed a toxic substance. Not just any toxic substance but one that I can fictionally mutate. Weird, I know. So I start to research and let me tell you...there's some really scary stuff out there! Makes me wish I wrote erotica. I'll bet those authors have fun with research. 

So what's the strangest stuff you've ever researched?
