yea. i did too after 5 mins. you push the cork in all the way and shake the coin out. simple. logical.

Or you could heat the bottle so the cork goes in like I said. Either way works mine just takes a little more effort.

You could do it scientificly and heat the bottle causeing convection currents and expanding the glass. which causes the cork to be sucked down into the bottle. Thus you have not removed the cork but have gotten to the money. oh sorry i didn't read yours all the way through. but yea yours works as well!

Because cigars cannot be entirely smoked, a hobo who collects cigar butts can make a cigar to smoke out of every 5 butts that he finds. Today, he has collected 25 cigar butts. How many cigars will he be able to smoke?

x+y doesn't = y, so therefore 2 does not = 1

and the hobo can smoke 5 cigars (maybe this is one of the riddles where the answer is so easy people second guess themselves)

Karl - he divided both sides of the equation by (x-y) that is how he got that answer.
I didn't really look at the problem, but I'm pretty sure the trick has to do with you are disregarding a possibly solution with imaginary number (i). No Karl - not a figment of you imagination, in the math world their is actually points in mathematics called "imaginary" but not in the same sense you think of it.

yeah, i know about i....learned it in algebra 2....but i dont see how that could be applied here, because there are no negative radicals involved

heres one from that berkely site...i actually knew the answer:
________________________ / \ | 0 0 0 0 0 0 0 0 0 | | | | | |___/---\_________/---\______| 0 0
This is a picture of a bus (drawn symmetrically). The bus is moving forward. Which way is the bus moving, to the right or to the left? You may ask as many questions as you need to determine the answer.
(it didn't copy right, but imagine that it IS symmetrical)

karl about mine, you're wrong
x=y x^2=xy x^2-y^2=xy-y^2 (x+y)(x-y)=y(x-y) x+y=y 2y=y 2=1

and the hobo can smoke 5 cigars (maybe this is one of the riddles where the answer is so easy people second guess themselves) Acyually the anwser is 6 because he can make another from the 5 that he just smoked.

At least he took a guess... that's better then you did.
