 Posted: Thu Mar 01, 2001 1:56 am    Post subject: 2 Can anyone show a digram? Here's mine: wrap your legs around the column and (assuming you're a contortionist) attempt to turn upside down. Once you've done that, flip the switches like this, 0 an even number of flips, 1 an odd: code:``` 0000, 0001, 0011, 0010, 0110, 0111, 0101, 0100``` or you could simply check one switches position, flip it back, and then put all the switches in the position it had been in, and finally get off and flip the first switch. If you can feel the position the switches do #2, if you can't, do #1. ------------------ My sister knows the difference between a cantelope and a melon. True, there isn't a difference, but she knows what the difference is.

Move 1, you get the first 2 digits: 1001 After your solution we should get 1001 Move 2, so happen you still get the first 2 digits but you don't know it. After your solution we will still get 1001. And clearly Move 3 will not solve it.

 Posted: Sun Mar 04, 2001 2:07 pm    Post subject: 4 Ok, I've solved it now. 1st Move Put your hands into any 2 adjacent hole. Switch them both up or down and if the chamber still doesn't open, put the left one down and the right one up. Now we're left with only 2 possibilies: 0101 or 0110 - always assuming we put our hands into the left digits. 2nd Move Put your hand into a hole. Feel it. If it's a down, putting a hand into the hole on the right and finding a up switch won't make any sense as you've already know that. So put your hand into the hole on the left (remember you can put your arm around the pillar). If the left hole is a down too, then flip it and the chamber will open. If not then the arrangement must be a 0101 pattern, go on to Move 3. Now if the first hole in Move 2 was up, then you put your other hand in the right hole. If it's the same then flip them to open the chamber else leave them alone and proceed to Move 3. Move 3. The only arrangement left is 0101, alternating switches. All you have to do is put your hand in opposite holes and open the chamber. And yes, move 3 and 2 are interchangable just as Darius has said. But i think darius failed to mention in his solution that you should take careful note of the positions of the switches after Move 1 and decide carefully which holes to put your other hand into in Move 2. Other than that it's somewhat similar.
