Don’t hate Neil deGrasse Tyson for pointing out where multiple Oscar winning film Gravity departs from the physics. The American astronomer argues that he’s a fan of the film and that its special effects got most things spectacularly right.
One of the most poetic moments in the film sees a weightless teardrop floating in mid-air, but Tyson explains that the real physics of surface-tension in microgravity is even more interesting (as demonstrated by astronaut Chris Hadfield), in that tears will tend to adhere to the face, rather than float freely.
*** SPOILER ALERT from about 1:40 ***
