Sometimes, in my unusually useful moments of boredom, I google completely random things.
You would be amazed what I find on the Internet by just thinking completely random thoughts and typing it in. Is that weird or is it useful?

Just now I typed into my google toolbar "What's in a penny?". I found a history of pennies and I learned that they are mostly made of Zinc. But on a website I visited there was a link that said "Can a penny dropped from a tall building kill you?". Of course, being the curious and bored person that I am, I clicked the link. It said that it would probably just sting a pedestrian. (Referring to being dropped off the top of the Empire State Building.) But then I googled the question exactly and found that it could in fact hit your head hard enough to knock you out or kill you. Of course I didn't know which was correct so I kept googling.
One website said only if your mouth is open and you choke. But I wonder if it wouldn't be the equivalent of choking but similar to shooting a bullet through your mouth. After a few sites and some strange idiots, I found that Mythbusters did an episode on it. Of course, I had know idea about this when I googled "What's in a penny?". I searched for Mythbusters on google.

Well, I couldn't find that one specifically so I am still left with the question "Can a penny dropped from the Empire State Building kill you?". But I think that the better question is, in fact, "Who in their right mind is going to go to the top of the Empire State Building to drop a penny?"
Time to google!
