The Magnificent Bastard Rep: 69Joined: 28 Dec 2006 Posts: 19,620 | heres a few to get you started.
Imagine you are in a room with 3 switches. In an adjacent room there are 3 bulbs (let’s say in lamps which are on a regular table), each switch belongs to one bulb. All are off at the moment. It is impossible to see from one room to another. No help from anybody else is allowed.
How can you find out which switch belongs to which bulb, if you may enter the room with the bulbs only once?

A table tennis ball (= a ping pong ball) fell into a tight deep pipe - it is about 30 cm long, buried in concrete pavement, having firm metal bottom, only 1 cm of the pipe is above the ground so it can not be moved. The pipe was only a bit wider then the ball, so you can not use your hand.
How would you take it out, with no damage?

A man lives on the tenth floor of a building. Every morning he takes the elevator down to the lobby and leaves the building. In the evening, he gets into the elevator, and, if there is someone else in the elevator - or if it was raining that day - he goes back to his floor directly. Otherwise, he goes to the seventh floor and walks up three flights of stairs to his apartment. How come?

How can you throw a ball as hard as you can and have it come back to you, even if it doesn’t hit anything, there is nothing attached to it, and no one else catches or throws it?

Let’s say some primitive organisms divide themselves every minute in two equal parts that are the same size as the original organism, and which also divide the next minute and so on. The saucer in which we started observing this process was full at 12.00.
When was it half full?

There were 4 angels on a Christmas tree (besides other frou-frou). Two had a blue aureole and two yellow, however none of them can see behind his head. Angel A is on the highest place and he can see angels B and C, which hang below him. Below hangs angel B, who can see only angel C under him. Angel C can’t see anybody, because angel D hangs under a twig (nobody can see him and he can not see anyone either).
Which one of them will be the first to speak his guess out load (deduce and say) what his own aureole is?

Well I sat here for awhile..
Thinking..
About maybe turning one on, leaving it on for awhile to let it warm, turn it off quickly, turn another one on and leave one off..
The one that’s warm belongs to the first switch, the one that’s on belongs to the switch you turned on before entering the room, and the one that’s off is the last switch you didn’t touch..
OR!
Just bring the lights into the room through the door.. (They are lamps on cords, right? Lol.)

Maybe you throw it so hard it gets stuck in the atmosphere and circles around the world.

Angel A. He can see the other two angels and make the best guess. Unless Angel B and C had different colors, than B, because he’d know (If he was smart enough.) That he didn’t have the same color as angel C.
BTW. This one is really close to a cannibal one I once did in school.

A possible solution but not the easiest one as it relies on power to get the vacuum cleaner to work, tis real easy and absolute answer requires no electricity

fill it with water, assuming it is closed at the bottom, which it would have to be for the ball to still be in there.

Which one of them will be the first to speak his guess out load (deduce and say) what his own aureole is?
i don’t know if i’m looking at this wrong, but i would think that it depends. if b and c have the same color, then a would know instantly what his is. if not, then b would be the first to guess because he only has one color influencing him, so he would automaticaly just pick the other.
