Knife throw in final leap-of-faith

During the final leap-of-faith in Assassin's Creed, the main character (Aguilar) visibly throws a knife at the water he is about to jump in to, presumably to break the water.

Is this possible, as in, would you be able to do this to avoid serious injuries from jumping in water from such height?

Best Answer

Nope. There is an old mythbusters episode on this.

"Dropping a hammer in front of you may break the surface tension, but it will not save your life because water is still too viscous to move out of the way quickly."

Haven't seen the actual movie, but if the jump is high enough to kill you when you hit the water, it will still kill you if you throw something in the water.

Is leap of faith possible?

Originally Answered: Is it possible to perform "a leap of faith"? No. Not only would your velocity and speed be too great, but hitting anything too hard can kill you, like water. Water feels like smacking onto concrete when hit from a high enough altitude.

Answer 2

Aguilar falls for around 8 seconds, which means (I am unable to know for sure, given that he falls in multiple positions), that he would be falling at 90% of terminal velocity. He would probably not survive. However, he would have fallen about 1029 feet, nearly a quarter mile. As far as I can tell, there was no such bridge in Spain, as the highest i can find is around 120 feet (at least that is in a similar location (it is in Rhonda)). Therefore, the jump was either cinematically slowed to accentuate Aguilar's acrobatics, or it is just ignoring historical construction. Either way, it is an epic sequence, which I enjoy very much. Perhaps the filmmakers made the jump farther in order to make the audience feel more of an impact while watching, as falls in movies seem less consequential.
