Dunk Tank in Green Bay

A dunk tank is a classic carnival attraction where a volunteer perches on a hinged bench above a tank of water and players throw balls at a target to release the seat and send the rider splashing in. Perfect for fundraisers, school carnivals, picnics and backyard parties, it’s an easy-to-run crowd favorite that creates instant excitement and funny photo moments. Rentals typically include the tank with safety cage and target, throw balls, and require level ground, a garden hose to fill a few hundred gallons, and an attendant to supervise; allow about 30–60 minutes to set up and roughly a 10–12 ft by 8–10 ft footprint. Safety first: one person on the seat at a time, no standing or diving, follow posted weight limits, supervise children, and empty/clean the tank after use.
