The Science of Senses

The piece of information that caught my attention, was that the coldest day in New Zealand was in Central Otago -21.6 degrees. It was warmer for them to hop in to their freezers then to stay outside! And the coldest day was in Marlborough Rangiora, and the temperature was 42.4 degrees.

Secondly, one of the organisers had a blow torch and blasted a hole through a zinc covered piece of metal. Green and white flames burst in to the air with a gasp of amazement from the crowd.In the end the back of it was a dark velvet purple, in the front it was white. He explained that the zinc was burnt off and the metal was rusting quite fast. It was very fascinating. It made me wonder a whole lot more about the world of science...
