With only days left until 2019, influencers are trying to raise awareness that it is important to practice champagne toast boomerangs ahead of time.

“We’re tired of seeing sloppy boomerangs,” said Fleur MacKenzie, Instagram model and artisan butter churner from Brooklyn. “People haven’t practiced the timing, the lighting, the angle. They’re insulting our profession, and we’ve had enough.”

It is recommended to try at least one per day in preparation for New Year’s. The Hamster reminds users to please boomerang responsibly this New Year’s Eve.
