Fun Stuff #5

Welcome to yet another edition of fun stuff!
Here’s some more logic puzzles:

Magnet
You are in a room where there are no metal objects except for two iron rods. Only one of them is a magnet.
How can you identify this magnet?

Castle
A square medieval castle on a square island was under siege. All around the island, there was a 10 metre wide water moat. But the conquerors could make foot-bridges only 9.5 metres long. Nevertheless a wise man was able to figure out how to get over the water.
What do you think was his advice?
(There’s a place on the other side to put the bridge against, not just a sheer wall. the water moat has square corners – that section of the moat is about 14.1 metres wide.)

Biology
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?

Answers on Sunday!
