I went to Island a few years ago and everyone should visit this wonderful place.
Below is a video of the famous Strokkur geyser which erupts every 4-8 mins.
Strokkur Facts

-Stopped working, but active again since 1963
-The geyser is 23 metres deep
-Water temparature is 120 degrees celcius, but because of the pressure it doesn't boil
