What happens when two black holes come in close proximity to each other? Will they "swallow each other up?

My younger cousin (9 yrs old) asked me this seemingly innocent question and I found it beyond my knowledge to give him a complete answer. I'd appreciate it if the community could provide one that would satisfy the questions of so young a "scientist".

why do rivers flow from north to south and not the other way around?

I have always observed that a river always flows from north to south before finally joining an ocean.. has this got something to do with the angle at which the north rotates or the magnetic fields of earth?

What % of the new money played on a slot machine is paid back assuming a stated 90% payback on each pull?

The payback percentage of a slot machine on a single play is usually around 90. This means that if 100 people play a dollar slot machine, on one pull $90 will be given as winnings. Now for subsequent plays part of the money played is won money. My question is, in the long run what is the percentage of the total new money spent that is casino profit? Don't forget that most players will keep putting their money back in until they have lost their limit. Very few walk away with the jackpot.

If it takes so much energy to move a person so far, does it take the same amount to walk as to ride a bike?

I thought that the same amount of energy was needed to move a something no matter how you move it, the energy just gets displaced. Where does it get displaced when you ride a bike?
Sorry, my headphones died on my morning walk so I had time to think about this.

Do you think a colony should be set up on another planet to ensure the survival of the human race?

Would you volunteer to leave Earth and become a member of an extra-terrestrial colony? Is the potential for global nuclear war on Earth a compelling reason to establish the colony? Would there be any guarantee that the colony would not repeat Earth's nuclear mistake? Aren't human beings their own worst enemies?

Is water kind of like energy, can't be created, can't be destroyed?

I remember from my youth a big "have to conserve water" campaign (during the Acid Rain scare) but I always wondered because don't we drink water and then either urinate or sweat it out and then it evaporates and then become clouds which rain and then we drink it again.
Doesn't the amount of water (overall in all forms) stay pretty much the same?
