When the piranhas invade your lakeside family reunion this year, guess who’s gonna be the only person to high-pressure hose his way to safety? Nooo, not former NASCAR great Dick Trickle (good/weird guess, though). You will be! Yes, you will able to evade those tiny teeth with the use of the Jetovator ($9,000); a water-powered (via personal watercraft) bikeish vehicle that goes up to 25 mph and 30 feet high. It also plunges you 10 feet below the surface, so once you escape the piranhas, you can drop back under the water to give them the finger (figuratively).
