The actual ball is called an 'Orb' and the activity is called 'Zorbing' or 'Globe-riding', 'Sphereing' or 'Orbing'.
Zorbing first began in New Zealand and was created by David and Andrew Akers. It is a recreational activity, and is great fun. It involves getting inside a big ball through a small hole in the side and then rolling down a hill while inside it. The runs usually run for about half a mile and the slope is usually gentle, but extreme Zorbing is done on much steeper slopes. Zorbing can also occur on flat ground when the person inside controls the orb by leaning against the sides. The longest ever ride recorded by the Guinness World Records in 2006 was by a man named Steve Camp who traveled 570 meters inside an orb. Another record was set by Keith Kolver who reached the fastest speed ever inside an orb when he reached 52km, 32.2mph.
Orbs can hold up to three people and it is possible to be harnessed or non-harnessed. The orbs have two sections, an outer ball and an inner wall. There is a thick layer of air between the two balls to protect the person inside. The air works as a shock absorber and is particularly necessary when the orb hits anything or takes flight.
For an added thrill, water is sometimes added to the orb and the people inside will get splashed when the orb rolls.
You can watch the Zorbing adventure on the Toyota advert on Youtube by following
