Yesterday’s Problem:
You have two glasses, one exactly half full of tea, the other exactly half full of milk. Take a teaspoon of milk from the glass and stir it into the tea. Then take a teaspoon of the tea-milk mixture and stir that into the glass with the milk.
Is there now more milk in the tea than there is tea in the milk? Or, is there more tea in the milk and milk in the tea? [This one is tricky, eh?]
Answer:
As tricky as the problem sounds, there is exactly the same amount of milk in the tea as there is tea in the milk.
Today’s Problem:
Two glasses filled with water are balanced on a scale. What happens to the scale when you stick your finger in one of the glasses? Will that side of the balance tip as it it were heavier?
How would the result change if your finger were made or heavy metal or wood?
