1. Find a direct path of going from A1 to A2, B1 to B2, and C1 to C2, without crossing lines or touching any border. This one is one of my favorites:

2. You have two sand watches, one of 7 minutes and the other one of 4 minutes, now you want to measure 9 minutes, how do you do it?
3. You have two ropes and a lighter, each rope burns in exactly 60 miutes, and not lineraly (meaning that some parts of the rope burn faster than another part), you want to measure 45 minutes, how do you do it? This one is beautiful, it took me some time to solve it.. the answer suddenly popped in my mind when i was driving my car toward home!
4. You have three cups, one of 5 liters, one of 3 liters, and one of unlimited place (assume we live on an extraterrestial planet where such cups exists), we also have an unlimited supply of water. We want to have exactly 4 liters in the unlimited cup, how do you do it? This one is quite easy but still nice.
5. You have 8 bags full of pieces of gold. In 7 of the bags, each piece weight exactly 1 gram, while in the other bag, each piece weight exactly 0.9 gram. You don't know which bag is which (of course), how do you find out which bag is the one with the lighter pieces when you have only one possibility of weighting using an electronic weighting device. -
