Observation of the coin at the bottom of a beaker lying below the line of sight

Method
  • Take a steel glass, a coin and some water.
  • Put the beaker on a table and drop a coin into the beaker.
  • Shift your head in the backward direction until the coin lies outside the line of sight, that is, until it is not visible.
  • Keep your head still at that point and ask a friend to pour water into the beaker without disturbing the coin.
Discussion
  • Does the coin reappear as the level of water rises?
