I know that the title raises some eyebrows and may sound somewhat non-hygienic, but the video below will make you think otherwise.
This is a great contraption that combines a sink on top of the toilet. As you flush the toilet, the sink turns on and provides clean water for you to wash your hands with. The water continues to run for as long as the toilet is filling up.
What an imaginative way that does not require hi-tech and scary devices. It truly lives up to the 2 in 1 slogan that many products claim to fulfill.
