Everyone knows that Scottish people are the most creative in the world (Alexander Graham Bell, James Watt, Thomas Telford…more here). Naturally, you might assume that those in Nova Scotia are also quite creative and, judging from the students at Dalhousie University in Halifax, this would appear to be the case.

Clever students from Dalhousie invented this wheel with grass growing on the inside. It enables one to walk on grass around the city in bare feet, while simultaneously avoiding (compressing) nasty things like dog doodoo and small children. Well done guys!
