If you’re sitting there mouthing ‘Up, up and WTF?’ whilst fumbling about for your popped-out eyeballs, prepare to be totally blown away as we tell you about this amazing water-powered jetpack. The result of years of painstaking R&D, the precision-made JetLev allows you to achieve stable, controlled flight as you soar 10 metres above the water at speeds of up to 35km/h. Best of all you’ll look like some kind of unhinged superhero. Jetskis and paragliders? How passé.
