"Ouch! Oooch! Cold, cold cold." Sonia danced around, and Papa removed it.
Sonia frowned at the ice necklace, and then went back to play with her blocks.
"It's sad though, that water is one of the few substances to behave that way. If it
were not for this strange behaviour of water, pipes would not burst in cold
places and inconvenience the people living there." Tania lamented.
"True, but this anomalous behaviour of water makes it possible for fishes and
other aquatic animals, living in ponds, and lakes to survive the winter in very
cold places." Papa pointed out.
"How so?" Tania's frowned trying to figure out the reason.
"You remember, I told you that ice floats on water, because of the anomalous
behaviour of water?" Papa asked.
"Yes." Tania replied and waited.
"So when a lake or a pond starts freezing in cold weather, the ice floats on top.
Once the lake is covered with floating ice, the ice forms a barrier between the
air above it and the water below it. Since the cold air can't come in contact with
the water, it cannot cool it much." Papa continued.
