• Why the fuck is it possible to lift a person with two fingers.

I guess everybody heard once or twice about this party trick when a person relaxes his body while laying on the ground and the other four people, using only their fingers, lift the person up with no difficulty at all. How the fuck is it possible, how can you explain it with physics? Wikihow: [url=http://www.wikihow.com/Play-Light-as-a-Feather]Link[/url]
because there are four lifters
Pressure. It's how spike beds work.
I spent some time looking it up back in high school and came up with a bunch of nonsensical explanations. I only came across one believable theory. Theoretically, when you do this, you're tricking your mind. Saying "light as a feather, stiff as a board" or holding your hands above the subject's head in preparation to lifting them out of the chair, you subconsciously know that the person is going to be heavy, so your body exerts more energy or strength in lifting the person. Multiply that by four or six, and you've got some strength. There's also theories about it really being white witch magic and somehow interrupting the magnetic field surrounding the person. Like I said, only found one believable one.
Why is this so difficult to understand. The weight of the person is equally distributed across the 4 people lifting him up. Therefore each person only has to exert 1/4 of the force necessary to lift the person. Your fingers are stronger than you think.
Because your fingers are significantly stronger then people believe.

Your first two fingers are quite strong. If you lift with all 4 fingers, it's not much different because your pinky and ring fingers are very weak. Then, there's 4 lifters, all lifting at once.
There's a reason you use those two fingers for lifting shopping bags.
