A group of Norwegians have invented an entirely new sport that has to be seen to be believed: Bubble Football/Soccer.

The game sees players run around the pitch wearing what could be loosely
described as giant, inflatable hamster balls on their heads. It
obviously impairs their movement and agility, but they simply bounce
safely whenever they take a spill.

The game is the brainchild of Henrik Elvestad and Johan Golden.
