The waterfall in Dubai Mall is 24 meters tall and has a circular shape; its diameter is over 30 meters. It is usually referred to as the Human Waterfall in Dubai Mall, due to the sculptures of men diving in. The falling of the water is designed to create a visual illusion, making it seem that the divers are moving instead of the water. The figures are sculpted in fiberglass and represent pearl divers jumping into the water. Pearl diving was the main source of livelihood in the UAE, and the basis for the founding of Dubai and Abu Dhabi.
