It won't be long until Times Square will be packed with spectators eager to say goodbye to 2019, and usher in a new year and a new decade.

The ball drop is the iconic moment, but the confetti falling from the sky also plays a big part in the city's New Year's Eve celebration.

That's why on Sunday, the Times Square Alliance organized the often overlooked but nonetheless important confetti test.

“It’s incredibly important to have every piece of the event go well, including the confetti because the world is watching, over a billion people world-wide,” said Tim Tompkins, the president of the Times Square Alliance.

Crowds gathered under a marquee on Broadway to see the colorful pieces of paper swirling in the wind. Many say it's like getting a preview of the upcoming party.

“I love confetti for birthdays and big celebrations. It’s my favorite part,” said Suhina Sharma, a Virginia resident.

 “[It’s] very cool to experience something that will happen on New Year’s Eve without being here that night, to kind of get a little taste of it is really cool and great for the kids,” said Sheryl Wilson.

Every year, groups of volunteers are perched along the surrounding buildings to toss handfuls of confetti on the massive crowd. This year, 100,000 of the vibrant hues also had wishes and resolutions on them, the most of any prior celebration. Some will miss out on the main event in Manhattan, but say the confetti test makes them feel like they're part of it.

“It gives off a vibe like a really good vibe,” said one woman. “It makes everyone happy and together,” said another.

There’ll be a lot more confetti during the celebration on Tuesday. Just come down to Times Square. The show kicks off at 6 p.m.
