Put your thinking cap!

In the long nights of autumn, why donft you solve a couple of puzzles? Ifve found some through the Internet that allow us to use freely. Then Ifll show you easy ones, so please try to solve them.


Marine
The captain of a ship was telling this interesting story. gWe traveled the sea far and wide. At one time, two of my sailors were standing on opposite sides of the sip. One was looking west and the other one east. At the same time, they could see each other clearly.h How can that be possible?



Bulbs
There are three switches downstairs. Each corresponds to one of three light bulbs in the attic. You can turn the switches on and off and leave them in any position. How would you identify which corresponds to which light bulb, if you are only allowed one trip upstairs?


Can you come up with the solutions?

It seems like no one could solve these two puzzles. I think there should be some answers. Ifll give you a sample solution for each one.


Marine-solution
The two sailors were standing back to the edge of the ship, and they were looking at each other. It does not matter where the sip is, but of course it does not apply to the North and South Pole.


Bulbs- solution
Keep the first bulb switched on for a few minutes. It gets warm. Then switch it off and switch another one on. After that, walk into the attic and make sure which bulb is on. So you can easily tell which bulb connects to the second switch. You can also touch the other two bulbs, then tell which one was switched on as the first one (the warm one) and the third one can be easily identified.


I hope you can understand my explanations. ;D
