jovana lara of kabc to strap on with shall we say mixed results. check it out. blast off. reporter: thrill-seekers, this is the toy for you. just imagine soaring over the ocean at 25 miles an hour. nearly 30 feet in the air. flying out in and out of the water, even checking in on folks on nearby boats. let me tell you, once you fly it, it is very addictive. reporter: jet-lev master and instructor steven gray shows you how it s done. we have arms we use to control it. pull down on the arms, we go forward. pull up on the arms we go back. reporter: the jet-lev water-propelled jet pack is the first of its kind and now available for the adventurist in southern california to take for a spin. seems so easy i gave it a try. once, twice i m flying, i m flying! three times. and almost had it. some of us just need a little more time. how bad was i? you weren t bad, you were great.
