TULALIP — Imagine a game being played in “huge bubble tanks.”

“They’re like tank suits,” Tulalip youth worker Deyamonte Diaz said. “Huge impacts happen.”

The game exists, and it’s called “knockerball.” Contestants organize into two teams wearing inflatable torsos.

Different variants of the game can be played, similar to soccer or football, but all involve full contact.

The Tulalip Youth Services has been working to organize knockerball leagues to take place every Tuesday at 4 p.m. at the field adjacent to the Don Hatch Youth Gymnasium at the 6700 Totem Beach Road.

“The goal is to have five-on-five soccer,” youth services worker Kyle Cullum said.

Participants can basically disregard all concerns of personal harm while colliding into each other at full speed, as the suits absorbs a tremendous amount of punishment.

“It definitely knocks you off your feet,” Diaz said.

Right now, the Tulalip youth have been enjoying wearing the suits and running into each other inside while playing pick-up games.

Youth services eventually wants to take the game outside as the weather improves and leagues form, Cullum said.

Outside of recreational use, the bubble suits have also serve educational purposes. They were used to educate youth on the effects of prolonged tobacco use. Because of the tubes’ encasement around the head, breathing can be somewhat difficult, simulating cigarette use, Cullum said.
