Hollywood Science
Die Hard page 1 2 3 4 5 6 7
Tough New York cop John McClane (Bruce Willis) is in a pickle. An office building has been taken over by terrorists, everyone else (including his wife) is being held at gunpoint and now they’re threatening to blow up the roof of the building. Mmm, now he’s on the roof of the building and the bad guys are blocking the only exit.

Thinking quickly, Bruce wraps a firehose around his waist and leaps off the side of the building, just as the roof explodes in a mass of broiling flames. It looks great on film, but is this another case of Hollywood Science?

Our Hollywood Sciencebusters Jonathan Hare and Robert Llewllyn did some detective work and found out that the fire hose was indeed strong enough to hold Bruce, but wasn’t very elastic. They claim he would be neatly sliced in two if he really tried to bungee with a fire hose. Yes, yes, we know they did the experiments, but can we prove this theoretically?
