1) It's not meant to shield you, it's meant to amplify your waves do make them less susceptible to interference from mind control rays. This is a joke. 2) Look at who did the study. Did they think about multiple people against a single animal? cowtipping does exist, but farmers will get really mad if you try it, and rightfully so. Cows can die from internal ruptures when knocked over. This is NOT a joke. 3) if you lie very still, especially if you can grab onto something else to pull, you might be able to slide yourself over the top. It helps to be really fat, too, because you're more buoyant. This is not a joke. 4) They really did, but everyone reading it says the idea is crap. 5) I thought it was after his silly walks gags, but whatever.
I'm also glad to see the reseachers cited in 2) also expose the myth that cows sleep standing up. Every sleeping cow I have ever seen (I grew up on a farm in the midwest with about 40 head of cows) slept upright with their legs tucked underneath. It wasn't until I was in college that I heard about cow tipping, and the stories always started with the presumption that cows slept standing up. Most cow -tipping story tellers, when further questioned, admitted that they never actually made it to the point where they tipped the cow over.
I realize the difficulty of proving a negative, and my own observations are based on a population of several hundred black angus cows. Yet I don't believe anyone has presented evidence showing a cow sleeping while standing. Of course, I've never seen proof of the flying spaghetti monster, and I certainly believe in Him.
Urban Myth or Just Plain Liars?
At a cocktail party in Chicago recently, someone recalled that as a youth on the playground, they were able to do a complete 360 degree turn around the swing set, looping the chain around the top. My friend immediately called "bullshit" on the guy. Several college educated professional types joined in the conversation, with three people recalling doing this on the playground like it was no big deal. I didn't say anything, but thought these people were delusional or liars - and no, there was no hint of irony in any of the recall.
Here's the question: Without an amount of force greater than that available on an average playground, doesn't the acceleration due to gravity overcome any angular momentum before the swing comes to the apogee of it's flight?
This would prevent the swing from swinging all the way over the bar, wouldn't it?
The more troubling phenom for me is the fact that there are people out there who seem to not only believe this is possible, but they believe they actually performed this act themselves.
Then again, 33% of americans believe that Adam and Eve rode dinosaurs to church on Sunday.
Anon's right. It's the same thing with the tooth in soda and how it's supposed to disappear overnight. TONS of people will say they did this and the tooth disappeared but I saw on Myth Busters the actual video footage and it doesn't. All it does is turn it brown.
