The halfway glass

Question

You are in an empty room with a glass of water.  The glass is a right cylinder that looks like it is about half-full, but you are unsure.  What is the most accurate way, without spilling any water, to determine whether the glass is half-full, more than half-full, or less than half-full?

You tilt the glass as far as you can without spilling any water. If water still touches any part of the bottom of the glass, the glass is more than half full. Otherwise less. If the water just touches the edge of the bottom, it's exactly half full.

You're right. I botched it. rodomac's wordless pics were in my mind, but they never made it to the keyboard.

"any part of" should be "all of."
