The Tornado, Hawaiian Waters Adventure Park's newest 4.5-story tube ride, is ready to roll, just in time for summer's peak.

Four people can ride together down the funnel-like tube, which cost about $2 million to install. It's included in park admission; full price is $37.99, but check the Web site and big-box clubs for promotions.
