Fireworks are no longer just for the Fourth of July. In recent years, cities around the world have boasted impressive fireworks displays to ring in the new year, and some of the most incredible can be found in Las Vegas, Dubai, Sydney and Rio. The four cities saw massive crowds on New Year's Eve ring in 2016 by watching the shows.

Las Vegas shuts down its entire bustling strip each year to make way for its $500,000 fireworks display. Financed by the Las Vegas Convention and Visitors Authority, fireworks are launched from the rooftops of seven hotels, including the MGM Grand, Aria, Planet Hollywood Resort, Caesars Palace, Treasure Island, the Venetian and the Stratosphere. Last year, around 300,000 people gathered to watch the fireworks, according to the Las Vegas Review-Journal, and this New Year's is expected to draw even larger crowds. The eight minute and 11-second choreographed show includes around 80,000 fireworks.

Massive crowds gather each year in Dubai beneath the world's tallest building, the Burj Khalifa, to ring in the new year. Dubai broke the world record in 2014 for longest and largest fireworks display and more than 650,000 people are expected to watch the 10-minute show at midnight Saturday.

Sydney boasts two separate fireworks displays on New Year's each year: one for the early birds and children and another for night owls who make it to midnight. The first takes place at 9 p.m. when fireworks choreographed to children's music are launched from the Sydney Harbour Bridge and four barges in the harbor. The second show is at midnight, a 12-minute display in which fireworks are released from seven barges, the Sydney Harbour Bridge and the Sydney Opera House.
