ince its debut in 1990,"Home Alone" has become as much a part of the Christmas cinematic ritual as "It's a Wonderful Life."
But unlike that uplifting tale about the good of mankind, "Home Alone" tells a rather unsettling Christmas story of a precocious 8-year-old who, accidentally abandoned by his family, is forced to defend his home from two dimwitted burglars.
The doctor weighs in >
Kevin McCallister (Macaulay Culkin) turns his family's home into a veritable funhouse of torturous booby traps that so-called Wet Bandits Marv (Daniel Stern) and Harry (Joe Pesci) hilariously stumble through, and the transformation of a suburban Chicago home into a relentless injury machine is nothing short of spectacular.
But it does require quite a suspension of disbelief.
Can a man really be hit square in the face with a steam iron and walk away unfazed? What kind of permanent physical damage would a blow torch to the head really do?
To answer these questions and officially dissolve "Home Alone"'s Hollywood magic, I spoke with my friend Dr. Ryan St. Clair of the Weill Cornell Medical College. Enjoy.
The injury: BB gun to the forehead
The set-up: Marv and Harry try to sneak into the McCallister home by sweet talking Kevin from the back door. Kevin, meanwhile, points his BB gun through the doggie door and directly at Harry's groin — and shoots. When Marv goes to investigate the source of Harry's pain, he is met by the same BB gun, which is fired at extremely close range to his forehead.
The doctor's diagnosis: "Classic air-powered projectile weapons typically have muzzle velocities of 350 feet per second or less. A BB fired at close range from such a weapon could break the skin, but will not penetrate the skull, and is unlikely to penetrate Harry's scrotum, especially through fabric."
The injury: Iron to the face
The set-up: Thwarted by the BB gun at the back door, Marv runs around to the basement stairwell — which Kevin has deliberately iced. Once he has stumbled his way down into the dark basement, Marv grabs for what he thinks is the light bulb cord. It's actually a rope attached to a steam iron that is propped up on the laundry chute door. The heavy iron comes plummeting down and smacks Marv in the face.
The doctor's diagnosis: "Let's estimate the distance from the first floor to the basement at 15 feet, and assume the steam iron weighs 4 pounds. And note that the iron strikes Marv squarely in the mid-face. This is a serious impact, with enough force to fracture the bones surrounding the eyes. This is also known as a 'blowout fracture,' and can lead to serious disfigurement and debilitating double vision if not repaired properly."
The injury: Handling a burning-hot doorknob
The set-up: While Marv is getting an iron to the face, Harry tries to enter the home through the front door. The first attempt doesn't go well, as the stocky burglar slips on the icy steps and falls to the ground, landing with a thud on his back. Easing up a second time with the help of the railing, Harry makes it to the front door, reaches for the doorknob — which we see is literally burning red — and grasps the searing handle, the pain of which forces him once again down the icy steps.
The doctor's diagnosis: "If this doorknob is glowing visibly red in the dark, it has been heated to about 751 degrees Fahrenheit, and Harry gives it a nice, strong, one- to two-second grip. By comparison, one second of contact with 155 degree water is enough to cause third degree burns. The temperature of that doorknob is not quite hot enough to cause Harry's hand to burst into flames, but it is not that far off... Assuming Harry doesn't lose the hand completely, he will almost certainly have other serious complications, including a high risk for infection and 'contracture' in which resulting scar tissue seriously limits the flexibility and movement of the hand, rendering it less than 100 percent useful. Kevin has moved from 'defending his house' into sheer malice, in my opinion."
