Thats steam ;) .

REAL electric trains dont burn anything in order to propell themselves so there is no smoke.

how was it steam if there was no water?????????????????

and no one said 2 REAL trains

Here's a riddle.

There's a table with an infinate amount of quarters. 100 of those quarters are tails-side up, the rest are heads-side up. You're blind and you have mittens on (you can't feel the faces of the quarters). How can you seperate the quarters into two piles so that both piles have the same amount of quarters tails-side up (the two piles do NOT need the same amount of quarters, just the same amount of quarters with the tails-side up)?

lick the quarters to feel which side is which :P

or just take the dumb mittens off.. what fool (even if your blind) attempts to handle change with mittens on..

and who the hell wears mittens anymore to begin with...

tho since theres an infinite number of quarters.. youll be making 2 piles for infinity anyways

it doesn't matter if there're infinate quarters, all that matters is how many quarters are tails up in each pile. duh.

just flip all the quarters over... the 100 tails will turn to heads, but the rest will be tails.. i forgot where i was going with this...

well then i must ask...

why would a blind person care if his change is heads up or tails up

close, but then you'd have a pile w/ 100 heads, and a pile w/ infinate tails.

and blind people like riddles too.

This is not a good way to phrase this riddle. First of all, you're taking the abstract concept of infinity and applying it to the concrete example of quarters on a table. That doesn't make any sense, so of course you're going to lead to confusion like diamond's (who did present a valid point). Instead, pick an arbitrary large number. Here's an easier-to-use version of the riddle:

Frozen Fingers Problem:

You are lost on the Arctic Tundra. And, unfortunately, you have been stricken blind. You meet a stranger who says he will help you find your way home if you can solve this problem. There are 100 quarters lined up on the frozen ground. Twenty of those quarters are "heads" up. The rest are "tails" up. You have to figure out how to make 2 groups of quarters that both have the same number of up turned "heads". But remember you cannot see the quarters because you are blind. And you cannot feel the quarters because your fingers are frozen.

There are still some logical issues with this one though. For example, if you're blind and numb, how do you pick up the quarters to begin with. Still, it's a little easier to wrap your head around. The answer that the riddle is looking for (barring balancing them sideways or anything like that) is a certain flipping pattern that I won't describe in case someone else wants to solve it.

wow good job reviving a thread thats 4 years old hahaha
