Corker (Posted on 2006-10-02) Difficulty: 2 of 5
Take a glass that is partially filled with water and drop a cork into it. The cork won't float in the center, but keeps drifting to one side and attaching itself to the side of the glass.

Without swirling the water, how can you make the cork float in the center?
