Slipping on ice

            December month. An afternoon, just after the white Christmas in Aarhus. I, with some other friends, was roaming around on the street. It was white everywhere with snow. We had holidays till the 3rd of January and were free. All the water bodies around us except the water of Kattegat sea were solid. I didn't realize what happened to me suddenly and I ran alone to the solid water beside the street from our group. It was solid water and we can walk but I didn't know the slippery surface. I slipped and fall down on the surface of the solid ice and could not stand, I was already a bit far from the street due to sliding. From there I crawled back to the street. All my friends were laughing at my situation of how I was coming back. Oops, a horrible experience as I was really frightened in the middle of the ice surface.

The Science behind: The surface of ice always have a thin layer
 of water. It is known fact that water on a smooth surface is slippery due to low viscosity of the water. It is similar like when water spilled on the tiles floor makes the tiles slippery. I did not know that before. Luckily nothing happened to me that day but it could be really dangerous.
We need to be careful....
