Movie physics
I saw the beginning of the movie “Cellular”. Kim Basinger gets kidnapped, taken to a house, and tossed on the floor–on a conveniently placed rug. The kidnapper then gets a big sledge hammer and swings at an old-style Bell phone. Phones are important in this movie, huh? The unbelievable thing is that the phone shatters into smithereens! A Bell phone come apart like that? Not in this universe!
A few minutes later, the director decides we didn’t just see the phone shatter. It turns out it was only slightly wounded and Kim makes a call. Now that’s a Bell phone!
