National Day celebrations also include fireworks celebrations. They feature several local and foreign teams which launch fireworks displays on different nights. First held in 2004 at Marina Bay, the event was initially known as the Singapore Fireworks Festival and organised by Unusual Productions. The amount of fireworks used has grown in magnitude over the past three years, from 4,000 rounds used in 2004 to over 9,000 in 2006. In 2012, a Mentos commercial encouraged procreation during the same time as the fireworks celebration.[1]
