7 Happy Movie Endings That Are Totally Ruined By Science

4. Princess And The Frog: One Kiss Causes Nuclear Winter

If the idea of kissing a frog to turn it into a prince is some kind of analogy for those new-relationship "fireworks", then it's a good one.

Due to the laws of the conservation of mass, thefrog would have to draw energy from its surroundings in order to make up the difference in mass and turn into a prince. We know from Einstein that mass and energy are pretty much interchangeable in physics, and since molecules can't be absorbed as easily as energy, converting energy to mass is the better way to do it.

Note I said "better" way, because it is still by no means a good thing.

All this energy has gotta to come from somewhere. More specifically, the kinetic energy from the surrounding air - and by "surrounding air", I meanalmost all of the air in the atmosphere.

Turns out that stripping the kinetic energy from air is not a good idea as it would immediately create an absolute zero temperature environment (that's the equivalent of -273.15°C, fact fans), and transforming the two most abundant gases in the atmosphere, nitrogen and oxygen, into liquids.

So, ask yourself the question, is your prince charming worth immediately drowning in liquid nitrogen?

Probably best to just try speed dating or something.
