Officials all across the United States sound the alarm on a new TikTok trend dubbed the “Orbeez Challenge.”

This challenge consists of young people using gel blasters, which are essentially airsoft guns specially made to fire Orbeez, to shoot the squishy projectiles at unsuspecting people going about their day-to-day lives. As you can imagine, this challenge is by no means harmless, even though Orbeez are made of gel.

Earlier this month in Utah, a group of teens was driving around a parking lot and firing Orbeez at unsuspecting people. As a result, bystanders blocked the “juveniles” in, with one man even drawing his firearm and demanding that the teens hand over their gel gun. Another person on the scene also allegedly punched one of the teens multiple times before retrieving the gel blaster.

Similar incidents occurred within the same state earlier this week. One March 15 occurrence involved two masked men entering a restaurant and firing the gel gun at diners—who weren’t aware that the projectiles were nonlethal until after being shot.

A “drive-by Orbeez shooting also accosted further southeast, a Florida mother and her young child,” Similar incidents in the Sunshine State led to an Amazon delivery driver and a 10-year-old child getting pelted. Sean McMullen, 19, was ultimately arrested for the latter two occurrences.
