This is probably one of the most popular questions everyone is asking after the show! From flooded stage to completely dry in the matter of 1 minute! As well as the 65 performers involved in the show, there is 70 to 80 technical staff involved at any given time (including 5 scuba divers in the tank ready to assist with speakers and cameras so they can see what is happening above!). The larger pool that covers the who stage can in fact drain in just 90 seconds! The floor around the pool is a sponge that has holes in it so that water can drain through. "There is an SFX (special effects) pump room that has two 300 HP pumps pumping 1,000 litres of water per minute. There are four big 600 mm pipes that carry out the quick drain operation from the main performer pool. We have the ability to fill the pool 30 cms and drain the pool 30 cms. There is also an in-between storage tank, where the water is temporarily stored". - Julian Zazzaretta, technical director of La Perle (quoted in an interview from MEP Middle East)
