Brain teaser 1:

You have to get to point B from point A of a field. Travelling from points A and/or B to the centre of the field takes exactly 5 minutes and 01 second. There is a monster in the middle, which wakes up exactly 5 minutes the moment somebody steps on the field, and will throw the person to the point where he is nearer to.

Question: How do you get from point A to B or B to A?

I know this is an ugly pic.



Brain teaser 2:

Four friends- A, B, C and D - meet up for sauna sessions every Saturday morning. One morning however, D was discovered dead in the middle of the sauna room, with a stab wound in his chest. Police searched the crime scene, and only found a thermos flask, and a small puddle of water nearby where D lay dead. The thermos flask was found to be A's, but no evidence of a murder weapon was ever found.

Question: What was the murder weapon A used to kill D?

Answer 1: Walk towards the monster from point A. At exactly 4:59, turn around and walk back to point A. The monster will think that the person came from point B, and will proceed to "throw him back to point A".

Answer 2: The murder weapon was an icicle, hidden in A's thermos flask. That explains the puddle of water around the dead D.
