There are 20 people in an empty, square room. Each person has full sight of the entire room and everyone in it. If you are not allowed to move in any way (other than your eyes).
Where can you place an apple so that all but one person can see it?
You have a bowl of water. Placed in the center of it is a paraffin candle. The water level is below the top of the wax by about a few milliliters. How can you use any ONE common household object so that when the candle is lit, the wick will go below the water level with the fire still going? A lighter is provided.
I Can Move While Sitting In One Place.
I can go up to 8 places in any direction.
When I can no longer move, I have to get up and go.
Who am I?
