Our Country is in good hands

KwaZulu-Natal MEC for co-operative governance and traditional affairs, Nomsa Dube, called on the national department of science and technology to investigate the causes of lightning after seven people died in lightning strikes.   
"We will do an investigation and talk to the department of science and technology on what is the cause of the lightning, and if it only happened to the previously disadvantaged as I have never seen any white people being struck by lightning" said Dube. She was visiting Mpumazi in Eshowe where seven people from two families died after being struck by lightning on Sunday.  "Scientists from the department could perhaps help us and come up with instruments that could help community members protect themselves against lightning. The department has dealt with floods and fires, but lightning is new to us," said Dube.

Our country is clearly in excellent hands!

Ice Berg's Art

Icebergs in Lake Michigan sometimes have stripes, formed by layers of snow that react to different conditions.
Blue stripes are often created when a crevice in the ice sheet 
fills up with melt water and freezes so quickly that no bubbles form. When an iceberg falls into the lake, a layer of water can freeze to the underside. If this is rich in algae, it can form a green stripe. Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the lake.
