Fireworks enthusiasts will be able to feast their eyes on the colours of the rainbow when more than 4,000 shells will be fired in synch to music during the feast of The Transfiguration of Our Saviour in Lija tomorrow.

The St Michael’s Fireworks Factory, which is celebrating its 85th anniversary, has been working on the two-hour fireworks display for the past year. It will in all use over 6,000 shells which will be let off from the Iklin valley between 9.30 p.m. and 11.30 p.m.

The highlight of the evening will be a 19-minute synchronised musical display – split into parts lasting six and 13 minutes – that will use up around 4,000 shells.

The six minutes of fireworks will be let off to a soundtrack from the famous blockbuster Pirates of the Caribbean while the remaining 13 minutes, wrapping up the show, will be accompanied by the 2002 Fifa track by Vangelis and the melodic Gregorian Chants.

The synchronised fireworks are let off remotely through a system called Fire One, which allows the enthusiasts to match the configuration and colours of the shells to the music. The computer synchronises the music and the time when the fireworks are let off.

The remote system cost thousands of euros and members of St Michael’s Fireworks Factory were the first to set it up.
