FLYING TIGER: A balloon of Derpy Tiger from KPop Demon Hunters appeared in the 2025 parade.

Every November, millions gather to watch larger-than-life balloons, fantastical floats, and live performers travel down the streets of New York City as part of the Macy’s Thanksgiving Day Parade. The event began in 1924 to ring in the holiday shopping season and quickly became a beloved tradition. Because the parade was briefly suspended during World War II, this year will mark the 100th time the event has been held!

Pulling off this parade involves thousands of people, dozens of balloons, and one special element: helium (He). This odorless, colorless gas has a lower density, or mass per unit volume, than air. That’s why helium-filled balloons float! Handlers on the ground use ropes to steer each massive parade balloon. Many balloons are shaped like popular characters from cartoons like KPop Demon Hunters, Pokémon, and One Piece.

Every November, millions gather to watch a spectacle on the streets of New York City. It includes larger-than-life balloons, fantastical floats, and live performers. This is the Macy’s Thanksgiving Day Parade. The event began in 1924 to welcome the holiday shopping season. It quickly became a beloved tradition. During World War II, the parade was briefly suspended. So it will be held for the 100th time this year!

This parade requires thousands of people and dozens of balloons. It also needs one special element: helium (He). This element is an odorless, colorless gas. It has a lower density, or mass per unit volume, than air. That’s why helium-filled balloons float! Handlers work on the ground. They use ropes to steer each massive parade balloon. Many balloons are shaped like popular characters. They’re from cartoons like KPop Demon Hunters, Pokémon, and One Piece.

Each year, the parade uses about 400,000 to 700,000 cubic feet of helium—enough to fill at least 800,000 party balloons!

Designers must consider a balloon’s shape, weight, and aerodynamics—how air flows around the object—to ensure it doesn’t spin or tip on parade day. They must also calculate exactly how much helium is needed to safely lift each heavy balloon.

“When our artists and engineers design the balloons, they’re balancing creativity with science from the very start,” says Will Coss, the parade’s executive producer. The result is a fun-filled spectacle that wows audiences watching in person and on their TVs at home.

Designers don’t want a balloon to spin or tip on parade day. So they must think about its shape, weight, and aerodynamics. That’s how air flows around an object. They must also calculate the exact amount of helium to use. Then each heavy balloon can be lifted safely.
