The UK television series Strictly Come Dancing and US counterpart Dancing with the Stars award competition winners a "Glitter Ball Trophy". Records English rock band Pink Floyd used a glitter ball on their A Momentary Lapse of Reason Tour of 1987 and The Division Bell Tour of 1994. The glitter ball used on the former was somewhat larger than normal but nowhere near as large as the glitter ball used on the 1994 tour. This particular glitter ball is one of the largest in the world: 4.90 metres in diameter, it rises to a height of 21.3 metres before opening to a width of 7.3 metres, revealing a 12 kilowatt Phoebus HMI lamp. Both can be seen on the video of each tour, Delicate Sound of Thunder and Pulse, during the song "Comfortably Numb". American singer-singwriter Madonna has used glitter balls in several of her tours. During The Girlie Show in 1993, she descended while sitting on one before performing "Express Yourself", and later in 2006, she used a 2-ton glitter ball that was embellished by 2 million dollars' worth of Swarovski crystals, which used an hydraulic system to open like flower petals for her entrance during her Confessions Tour. Despite claims that the world's largest disco ball can be found on the promenade in Blackpool, United Kingdom, it is smaller than the Guinness World Record holder. The ball was made for the 2014 Bestival event in England, and is in diameter. References Lighting Mirrors Dance equipment Ball
