Ah... I've been neglecting my puzzles, haven't I? I hope this one will be entertaining.
You have a glass with fluid inside, about half full. Without using any instruments, how can you tell if it is exactly half, more than half, or less than half full?
yay puzzles

If it's a rectangle, you can tip it on it's side and look to see the diagonal line. If it's perfectly straight then it's half full!
If it's not a rectangle, then I'm not sure.

It would be awfully hard to see if the bottle is exactly half full if the bottle isn't square or rectangular, Professor. There are no corners on a cylindrical bottle, so it would be hard to see if they lined up. I know you can still tell, though.
