  • If a bird is in an oil spill, oil coating its beak is just the beginning of its problems.

  • That's exactly correct. You're not understanding something here. The water droplet WANTS to be a sphere, but it isn't because it's sticking to the beak. In order to get CLOSER to sphere shape, it has to go where the beak is more closed, which is upward.

  • @crackerstolemybike Anyone who thinks the big bang was an explosion has no idea on what there talking about go back to school you numb minded fool.

  • @crackerstolemybike Mate shutup with your god mumbo jumbo.

  • if this videos doesent make you beliv in god what does. how can a bird like this be created by a big bang. you see fire works banging, they dont creat birds with anti gravity beaks. this is evidence that god is real, fact.

    face upto the facts non-belivers, god is real! you will be judged in 2012 then you will be sorry

  • @dafttool good thing there is no oil spills right now ... ohhh bp u idiot

  • yea, well my dick not only defies gravity, but it breaks the 2nd law of thermodynamics

  • my tweezers defy gravity

  • actually nothing 'defies' gravity it is just acted on by a stronger force. Pwned.

  • It only needs to move toward the area of the beak that is more closed if the water sticks to the beak though other wise it would just pull off of the beak and form a sphere at the bottom of the beak rather than pulling itself up. That is why oil spills mess up the ability to do this little trick; it coats the beak in oil and therefore allows the water to form a sphere at the bottom of the beak as opposed to sliding up.
