conversations.value: The coach has 8 liters * 1000 ml/liter = 8,000 ml of water.
  She pours 200 ml/player x 30 players = 6,000 ml of water in total for all the athletes.
  The water spill means 6,000 ml + 250 ml = 6,250 ml of water was used.
  There was 8,000 ml - 6,250 ml = 1,750 ml of water left.
