Two holes were cut in a lid of the box. A small coin was placed inside the box . Task was to see the coins through the holes.
Observation - It was completely dark inside the box and nothing was visible .
Then a strong beam of light was allowed to pass through one of the hole and coin could be seen through the other hole .
Observation - coin was clearly seen .
